Description

Alkoxylated fragrance alcohols and their use

The present invention relates to alkoxylated fragrance alcohols. In particular, the present invention relates to fragrance alcohols, especially terpene alcohols, with a defined number of ethσxy and / or prσpoxy groups in the molecule. The present invention further relates to the production of alkoxylated fragrance alcohols, in particular alkoxylated terpene alcohols, and their use in washing, rinsing, cleaning or conditioning agents or cosmetic preparations.

Terpenes and their osmophore-bearing derivatives play a central role among the fragrances, i.e. those regularly volatile substances that trigger a pleasant sense of smell in humans. Terpene alcohols in particular play an important role as fragrances: They were previously obtained from plant sources and are part of many essential oils, but are now also accessible synthetically.

Fragrance alcohol esters and especially terpene alcohol esters with inorganic acids or (optionally lower alkoxylated) carboxylic acids, namely fragrance alcohol-atherpene alcohol sulfonates, sulfates, phosphates etc. as precursors for fragrances in cosmetic preparations are described in WO 97/30687 (Givaudan -Roure International SA). The publication describes that the esters are odorless at room temperature and normal pressure, but under suitable conditions, for example on the Body surface when used as a deodorant, split and release the alcohols, which then show their organoleptic properties.

Czech Patent No. 253,437 describes the alkoxylation of linalool and dihydrolinalool and the use of the resulting products as low-foaming, nonionic surfactants in cosmetic preparations and “home care products”. Evidently, this patent utilizes the knowledge that the lipophilic molecules of the Linalools and dihydrolinalools can be rendered water-soluble by an alkoxylation and consequently show surfactant properties. Defined alkoxylates of the two terpene alcohols are not disclosed. A release of linalool or dihydrolinalool from the reaction products with ethylene oxide or propylene oxide is not postulated.

Fragrances have long been used in detergents, dishwashing detergents, cleaners or cosmetics as well as in cosmetic preparations. Nowadays, they serve less - as in earlier times - to mask unpleasant smells of the components contained in the above-mentioned agents or preparations, but are primarily used to treat both the products themselves and the objects or agents treated with the agents To give surfaces or the body or part of the body treated with the preparations a pleasant and long-lasting fragrance beyond the treatment. In addition, product identification is also achieved by the consumer via the fragrance of the product or the fragrance transmitted by the product to the object being treated; the advertising of the fragrance ("April freshness";"lemonscent") makes use of this product identification and is used to promote sales. The fragrance note is given a special place in advertising, and thus also in consumer presentation, especially for avivage products. As a result, there is a problem with both the manufacturers of detergents, dishwashing detergents, cleaning agents, and cosmetics as well as the manufacturers of cosmetic preparations Need for a way to fix fragrances on treated objects on the one hand and thus only to enable fragrances to be released after the treatment, but on the other hand also to extend the time for the release of the fragrances after the treatment.

The controlled release of fragrances in a wide variety of preparations in the washing, rinsing, cleaning and personal care sector, often referred to as "controlled release", is the subject of numerous publications and patent applications. This reflects the fact that the release of fragrances is of outstanding importance in this technical field, because - for the reasons mentioned above - both the product and the washing, rinsing, cleaning or finishing agent solution and those using these agents treated objects should be scented intensively and long-lasting. In addition to the methods of applying fragrances to carrier materials and coating the scented carriers or encapsulating or encapsulating fragrances or storing them in compounds (for example cyclodextrin-perfume complexes), there is the possibility of chemically binding the fragrances to carrier media, the chemical bond slowly being broken down and the fragrance is released. This principle has been implemented, for example, in the esterification of fragrance alcohols - as already mentioned above - a broad state of the art exists for this group of substances in addition to the publication WO 97/30687: for example, it is proposed to bind fragrant alcohols to non-volatile siloxanes which they are slowly released by hydrolysis. Furthermore, the older patent application DE 198 41 147.2 (Henkel KGaA) discloses esters of oligosilicic acids with scented alcohols, which enable objects (including the human body or parts thereof such as the hair) to be scented for a long time. However, problems arise when using the compounds of the prior art mentioned in detergents and cleaning agents and also in cosmetic preparations. For example, many of the known compounds cannot be used in aqueous detergents and cleaning agents, since they already hydrolyze in the product and thus delay the release. does not happen later. This is all the more the case since conventional washing and cleaning agents often have pH values which promote the hydrolysis of fragrance esters. However, incorporation of the previously known siloxane esters, for example, is also unsuccessful in powder detergents. Under normal manufacturing conditions of densified particle mixtures such as granulation or press agglomeration, the siloxane esters also tend to release the fragrance alcohol already during manufacture, ie prematurely. There is therefore a need to provide fragrance forms which scent both the product and the washing, cleaning or aviva solution or the cosmetic preparation, the fragrance on the objects treated, in particular on textiles, being intended to last as long as possible.

Surprisingly, it has been found that alkoxylated fragrance alcohols, in particular alkoxylated terpene alcohols, achieve the above objects. This is all the more surprising since ethers - and these include alkoxylated fragrance alcohols and alkoxylated terpene alcohols - have a comparatively high stability to hydrolysis in an aqueous environment. The alkoxylated fragrance alcohols or terpene alcohols according to the invention are notable for good adhesive strength. In addition, the alkoxylated terpene alcohols are excellent as fragrance boosters. A fragrance booster is to be understood as a substance that is able to give the olfactory impressions of the components of a multi-substance system, i.e. a mixture of two or more fragrances to intensify sustainably.

The invention therefore relates to alkoxylated fragrance alcohols of the general formula (I)

R ¹ 0 - [CH (R ² ) -CH (R ^{2 '} ) -O-] _n - R ³ (I) wherein

- R ^{1 represents} the scent alkyl radical of a scented alcohol of the formula R ¹ OH;

- R ² and R ^{2 '} independently of one another are hydrogen or a CH ₃ radical, at least one of the radicals R ² and R ^{2' being} hydrogen; - R ^{3 represents} hydrogen, an alkyl radical having 1 to 60 carbon atoms, a radical - (C = O) R ^{3 '} , in which R ^{3' represents} hydrogen or an alkyl radical having 1 to 60 carbon atoms, or R ¹ ; and

- R ^{3 represents} hydrogen, an alkyl radical having 1 to 60 carbon atoms, a radical - (C = O) R ^{3 '} , in which R ^{3' represents} hydrogen or an alkyl radical having 1 to 60 carbon atoms, or R ¹ ; and

- n stands for an integer from 1 to 100,

with narrow distribution of the number of ethoxy and / or propoxy groups.

The invention also relates to a process for the preparation of the above-mentioned alkoxylated fragrance alcohols of the general formula (I) by reacting a fragrance alcohol of the general formula

R ¹ OH,

wherein R ^{1 has} the meaning given above, with one or more alkylene oxide (s) of the general formula

OR ² - CH - CH - R ² wherein R ² and R ^{2 have} the meanings given above, in the molar ratio of fragrance alcohol: alkylene oxide in the range from 1: 1 to 1: 100 in the presence of an alkoxylation catalyst at a temperature in the range from room temperature to 200 ° C. and a pressure in the range from normal pressure to 10 Mpa, especially 1 Mpa, in the presence or absence of a solvent for a time until all of the alkylene oxide has been taken up, for example for a time in the range from 0.1 to 5 h, deactivating the catalyst and optionally isolating the product.

Finally, the invention also relates to the use of alkoxylated scented alcohols of the general formula (I) in washing, rinsing, cleaning and finishing agents or in cosmetic preparations.

The present invention thus comprises alkoxylated fragrance alcohols of the general formula (I)

R ¹ O - [CH (R ² ) -CH (R ^{2 '} ) -O-] _n - R ³ . (I)

In the above general formula (I), the radical R ^{1 is} selected from the group of fragrance alcohol residues R ¹ of fragrance alcohols R ¹ OH. In the context of the present invention, the term “fragrance alcohols” is understood to mean fragrance molecules which have free hydroxyl groups which can be etherified, regardless of how the molecule is further structured. Salicylic acid ethers are also conceivable as fragrance alcohol alkoxylates. Preferred representatives can be named from the large group of fragrance alcohols, so that alkoxylated fragrance alcohols of the general formula (I) in which R ^{1 is} selected from the group of the following fragrance alcohol residues: 10-undecene-1 are preferred in the context of the present invention -yl, 2,5-dimethylhept-2-yl, 2,6-dimethylhept-2-yl, 2-methylbutyl, 2-methylpentyl, 2-phenoxyethyl, 2-phenylpropyl, 2-tert-butylcyclohexyl, 3.5 , 5-Trimethylcyclohexyl, 3-Hexyl, 3-Methyl-5-phenylpentyl, 3-Oct- yl, 3-phenylpropyl, 4-heptenyl, 4-isopropylcyclohexyl, 4-tert-butylcyclohexyl, 6,8-dimethyl-2-nonyl, 6-nonen-1-yl, 9-decen-1-yl, alpha-methylbenzyl, alpha-terpinyl, amylsalicyl, benzyl, benzylsalicyl, beta-terpinyl, butylsalicyl, citronellyl, cyclohexylsalicyl, decanyl, dihydromyrcenyl, dimethylbenzyl, dimethylheptyl, dimethyloctyl, ethylsalicyl, hexylylylnesyl, gerylylylylnesyl, gerylylyllynesyl, gerylylyllynesyl, geryl Isoeugenyl, isononyl, isopulegyl, lavendulyl, linaloyl, menthyl, myrcenyl, myrtenyl, n-hexyl, neryl, nerodilyl, nonyll, octyl, para-menthan-7-yl, phenylethyl, phenyl, phenylsalicyl, tetrahydrogeranyl, tetrahydroloyl, tetrahydroloyl, tetrahydroloyl, tetrahydrylyll trans-2-cis-6-nonadicnyl, trans-2-nonen-1-yl, trans-2-octenyl, undecyl, vanillyl and cinnamyl. In a case in which a residue can occur in several isomers (for example farnesyl, nerolidyl), in principle all isomers or their mixtures are suitable, but preferred are those whose alcohol R ¹ OH leads to particularly good fragrance results.

In a preferred embodiment of the invention, the radical R ¹ in the general formula (I) is an isononyl radical. According to the invention, alkoxylated isononyl alcohols of the general formula (I) show outstanding properties in connection with the desired properties as long-lasting fragrances.

In a further embodiment which is likewise preferred according to the invention, the radical R ¹ in the general formula (I) represents a terpene radical of a terpene alcohol R ¹ OH. Particularly preferred according to the invention are alkoxylated terpene alcohols of the above general formula (I), in which R ^{1 is} selected from the group geranyl, citronellyl, tetrahydrogeranyl, linaloyl, dihydrolinaloyl, tetrahydrolinaloyl, neryl, myrcenyl, dihydromyrcenyl, lavendulyl, farnesyl, isolidophenylulentyl, menthyl Terpinyl, tetrahydromuguyl, thymyl, 2,5-dimethylhept-2-yl and phenylethyl. With alkoxylated fragrance alcohols of the general formula (I), in which R ^{1 has} one of the meanings given above, Apply long-lasting intensive fragrance notes to a wide variety of objects in dishwashing, cleaning or anti-aging agents or in cosmetic preparations.

According to the invention, the meaning of R ³ in the general formula can be hydrogen, an alkyl radical having 1 to 60 carbon atoms, a radical - (C = O) R ^{3 '} , in which R ^{3' represents} hydrogen or an alkyl radical having 1 to 60 carbon atoms, or R ¹ be where R ^{1 has} one of the meanings mentioned above. R ³ in the general formula (I) is particularly preferably hydrogen. The alkoxylated fragrance alcohols according to the invention, in particular the alkoxylated terpene alcohols, are therefore particularly preferably the non-derivatized direct reaction products of an alkoxylation of the corresponding fragrance or terpene alcohols.

According to the invention, in the general formula (I) the meaning of R ² and of R ^{2 '} independently of one another can be hydrogen or methyl (CH ₃ ), at least one of the radicals R ² and R ^{2' being} hydrogen. The alkoxylated fragrance alcohols or terpene alcohols are thus ethoxylates or propoxylates or alkoxylated derivatives of the corresponding fragrance alcohols or terpene alcohols which contain both ethoxy groups and propoxy groups. The above general formula (I) is to be understood in such a way that the group - [CH (R ² ) -CH (R ^{2 '} ) -O-] _n - in the molecule can only represent ethoxy groups (in this In this case, R ² and R ² only represent hydrogen) or exclusively propoxy groups (in this case R ² or R ^{2 stands} for CH ₃ ) or for the coexistence of ethoxy groups and propoxy groups in the alkoxylated fragrance alcohol. The number of alkoxy groups in the molecule - indicated by the index n - can vary within wide ranges and is, according to the invention, in the range from 1 to 100, preferably in the range from 3 to 50, more preferably in the range from 5 to 30 and most preferably in the range from 5 to 20. It is clear to the person skilled in the art in the field of alkoxylated derivatives of fragrance alcohols that although a general formula such as formula (I) is given, the value of n is an integer; practically arise However, as products of an alkoxylation, products with a distribution of the number of alkoxy groups over a certain range regularly so that a product for a product of an alkoxylation reaction carried out under certain conditions results in a general formula according to the pattern of the general formula (I) which However, the number n of the alkoxy groups actually present in the product is reflected in an average number, which can also differ from an integer in the range defined above.

In the case where in the molecule of the alkoxylated fragrance alcohols according to the invention, in particular the alkoxylated terpene alcohols according to the invention, both ethoxy groups and propoxy groups can be present as alkoxy groups, general formula (I) includes both alkoxylated fragrance alcohols in which ethoxy groups and propoxy groups are randomly arranged in the alkoxy chain (“random polymers”), as well as those alkoxylated fragrance alcohols in which blocks of several ethoxy groups in addition to blocks of several propoxy groups in the Chain are arranged ("block copolymers"). The latter alkoxylated fragrance alcohols, preferably alkoxylated terpene alcohols, can also be represented by the following general formula (Ia), which is a special case of the general formula (I):

R ¹ O - [CH ₂ -CH ₂ -O-] _k - [CH (R) -CH (R ^{2 '} ) -O-] _m - R ³ (la).

In the general formula (Ia), R ¹ , R ² , R ² and R ^{3 have the} same meaning as in the general formula (I), k is an integer from 1 to 99, m is an integer from 1 to 99 and the sum of k and m represents an integer from 2 to 100. The above formula (Ia) is to be understood such that a scent alkoxy radical / terpene alkoxy radical R ¹ O- is attached to an ethoxy block as well can also be bound to a propoxy block and the block bound to R ¹ O is then followed in each case by a block of the other type. Of course, a block of the other type can then be connected again, if necessary, even if this does not result directly from the general formula (Ia). The stipulations for the total number of blocks of the respective type as well as the total number of all blocks are the above-mentioned ranges of the numbers for k and m and their sum, which is in any case at or above 2 and should not exceed 100.

A particularly preferred embodiment of the invention corresponds to alkoxylated fragrance alcohols, in particular alkoxylated terpene alcohols, of the general formula (I) and of the general formula (Ia)

R ¹ O - [CH (R ² ) -CH (R ^{2 '} ) -O-] _n - R ³ (I)

R ¹ O - [CH ₂ -CH ₂ -O-] _k - [CH (R ² ) ^ CH (R ^{2 '} ) -O-] _m - R ³ (la)

wherein

- R ² and R ^{2 '} independently of one another are hydrogen or a CH ₃ radical, at least one of the radicals R ² and R ^{2' being} hydrogen;

- n is an integer from 1 to 100;

k is an integer from 1 to 99, m is an integer from 1 to 99 and the sum of k and m is an integer from 2 to 100;

with narrow distribution of the number of ethoxy and / or propoxy groups.

Such "narrow rank alkoxylates" - comparable compounds with a narrow alkoxylation range are also known in other fields of technology - lead to fragrance alcohol alkoxylates, in particular terpene alcohol alkoxylates, with particularly advantageous properties, for example in the controlled release of fragrance over a long time, and thus solve those of the invention set task in a surprising and convincing way. Particularly preferred in this context are those alkoxylated scented alcohols or alkoxylated terpene alcohols of the general formula (I) in which n is an integer in the range from 5 to 20 and by at most ± 3, preferably at most ± 2, by a certain numerical value fluctuates or k and m in the general formula (la) stand for integers in the range from 5 to 20 and fluctuate by at most ± 3, preferably at most ± 2, by a certain numerical value. For example, scented alcohol alkoxylates are particularly preferred according to the invention in which 3, 6, 7, 10 or 20 alkoxy radicals are bonded to a scented alkoxy radical or terpene alkoxy radical and the number of ethoxy groups present statistically in a large amount of the product Residues or propoxy residues in the abovementioned cases vary, for example, only between 1 and 5 or between 4 and 8 or between 4 and 9 or between 7 and 13 or between 17 and 23. Products with a narrow distribution of the number of alkoxy groups result in particularly good properties in terms of fragrance adhesion and release.

Particularly preferred but non-limiting examples of fragrance alcohol alkoxylates which can be used advantageously according to the invention on account of the good fragrance properties are the compounds represented by the following formulas (1.1.) To (I.8.):

Isononyl - O - [CH (R ² ) -CH (R ² ) -O-] _n - H (1.1.)

Geranyl - O - [CH (R ² ) -CH (R ^{2 '} ) -O-] _n - H (I.2.)

Terpinyl - O - [CH (R ² ) -CH (R ^{2 '} ) -O-] _n - H (I.3.)

Citronellyl - O - [CH (R ² ) -CH (R ^{2 '} ) -O-] _n - H (I.4.)

Farnesyl - O - [CH (R ² ) -CH (R ^{2 '} ) -O-] _n - H (I.5.)

Tetrahydromuguyl - O - [CH (R ² ) -CH (R ^{2 '} ) -O-] _n - H (I.6.)

2,5-dimethylhept-2-yl - O - [CH (R ² ) -CH (R ^{2 '} ) -O-] _n - H (I.7.)

Phenylethyl - O - [CH (R ² ) -CH (R ^{2 '} ) -O-] _n - H (I.8.) wherein R ² and R ^{2 '} independently of one another are hydrogen or a CH ₃ radical, at least one of the radicals R ² and R ^{2' being} hydrogen; and n represents an integer ranging from 5 to 20. These compounds also have particular advantages for those in which n fluctuates by at most ± 3, preferably at most ± 2, by a certain numerical value.

The present invention also extends to a process for the preparation of alkoxylated fragrance alcohols of the general formula (I)

R ¹ O - [CH (R ² ) -CH (R ^{2 '} ) -O-] _n - R ³ (I)

wherein

- R ² and R ² independently of one another are hydrogen or a CH ₃ radical, at least one of the radicals R ² and R ^{2 being} hydrogen;

- n stands for an integer from 1 to 100.

The method comprises reacting a fragrance alcohol of the general formula

R ¹ OH,

OR ² - CH - CH - R ² wherein R ² and R ^{2 'have} the meanings given above, in the molar ratio of fragrance alcohol: alkylene oxide in the range from 1: 1 to 1: 100 in the presence of an alkoxylation catalyst at a temperature in the range from room temperature to 200 ° C. and a pressure in the range of normal pressure up to 10 MPa, in particular at 1 MPa in the presence or absence of a solvent for a time until all the alkylene oxide has been completely absorbed, in particular for a time in the range from 0.1 to 5 h, deactivating the catalyst and optionally isolating the product.

The starting material for the first process step are fragrance alcohols or terpene alcohols of the general formula R ¹ OH. In this general formula, R ^{1 can have} all those meanings which have already been mentioned above in connection with the introduction of the new alkoxylated fragrance alcohols or alkoxylated terpene alcohols. Particularly preferred are fragrance alcohols or terpene alcohols from the group isononanol, geraniol, citronellol, tetrahydrogeraniol, tetra- hydrolinalool, nerol, myrcenol, dihydromyrcenol, Lavendulol, farnesol, neroli dol, menthol, isopulegol, terpineol, thymol, phenylethanol, tetrahydromuguol and Dimetol® ^R (2,5-dimethylheptan-2-ol), more preferably isononanol, geraniol, terpineol, thymol, farnesol, citronellol, tetrahydromuguol, 2,5-dimethylheptan-2-ol and phenylethanol. In a case in which an alcohol can occur in several isomers (for example farnesol, nerolidol), in principle all isomers or mixtures thereof are suitable, but those which lead to particularly good fragrance results are particularly preferred.

The scented alcohol R ¹ OH is combined with one or more alkylene oxides of the formula

R ² - CH Λ- CH - R ² wherein R ² and R ^{2 'have} the meanings given above, that is to say can be H or CH ₃ , where at least one of the radicals R ² and R ^{2 is} H. A reaction with only one alkylene oxide leads to alkoxylated fragrance alcohols or terpene alcohols with only one type from the group - [CH (R ² ) -CH (R ^{2 '} ) -Oj _n -, ie to fragrance alcohol ethoxides or fragrance alcohol propoxides, while the simultaneous reaction with ethylene oxide and propylene oxide leads to alkoxylation products in which ethylene oxide groups and propylene oxide groups are randomly distributed in the molecule (“random alkoxylates”), and the successive reaction with the two alkylene oxides to give alkoxylation products with successive blocks of ethylene oxide (EO) or propylene oxide (PO) leads, for example those as represented by the following formula (la)

R ¹ 0 - [CH ₂ -CH ₂ -O-] _k - [CH (R ² ) -CH (R ^{2 '} ) -O-] _m - R ³ (la)

wherein R ¹ , R ² , R ^{2 '} and R ^{3 have} the meanings defined above, k is an integer from 1 to 99, m is an integer from 1 to 99 and the sum of k and m is an integer Number from 2 to 100 stands.

When the fragrance alcohol R ¹ OH is reacted with the alkylene oxide (s), the molar ratio of fragrance alcohol to alkylene oxide (s) largely depends on the desired alkoxylation number of the fragrance alcohol or terpene alcohol and is preferably in the range from 1: 1 to 1: 100, even more preferably in the range of 1: 1 to 1:50.

An alkoxylation catalyst is used for the alkoxylation reaction, which can be carried out in the presence or absence of a solvent. An alkaline alkoxylation catalyst has proven particularly useful, preferably an alkali metal hydroxide. If a so-called "narrow-rank alkoxylation" catalyst is used, preferably a catalyst from the group of calcined talcites, the reaction leads to alkali oxylated fragrance alcohols or alkoxylated terpene alcohols with the particularly preferred narrow distribution of the number of ethoxy and / or propoxy groups.

According to the invention, the alkoxylation reaction is carried out at a temperature in the range from room temperature to 200 ° C., preferably in the range from 50 to 170 ° C., and at a pressure in the range from normal pressure to 10 MPa, preferably in the range from 0.1 to 1 MPa long until the alkylene oxide has been completely taken up, preferably over a time in the range from 0.1 to 5 hours.

After the intended reaction time has expired, the catalyst used is destroyed. This is done in a manner known per se to the person skilled in the art, for example by acidifying the reaction mixture to the neutral point. The product obtained can then be used for the desired purpose without any problems or, if appropriate, in a manner known per se, for example by distillation under controlled conditions, of starting materials which have not reacted, or of products whose degree of alkoxylation is not in the range desired for the product lies, separated and so isolated.

The invention also includes the use of alkoxylated fragrance alcohols, in particular alkoxylated terpene alcohols, of the general formula (I)

R ¹ O - [CH (R ² ) -CH (R ² ) -O-] _n - R ³ (I)

It has been surprisingly found that the task of providing cosmetic preparations and washing, rinsing, cleaning and finishing agents with a longer-lasting fragrance and of the agents on the treated objects or on the human body or parts thereof - transferred, can be solved if alkoxylated fragrance alcohols, in particular alkoxylated terpene alcohols according to the present invention are used in the respective compositions or preparations. In this way it is achieved in particular that the fragrance is intensified and lasts for a long time. The use of the following alkoxylated fragrance alcohols (1.1.) To (I.8.)

The surfactant-containing preparations according to the invention contain one or more alkoxylated scented alcohols of the general formula (I) in an amount of 0.001 to 10% by weight, preferably in an amount of 01 to 5 wt .-%, particularly preferably in an amount of 0.02 to 3 wt .-% and in particular in an amount of 0.05 to 2 wt .-%, based on the surfactant-containing washing, rinsing, cleaning - or finishing agent preparation. In addition to the alkoxylated fragrance alcohols mentioned, the surfactant-containing preparations according to the invention contain one or more substances from the group of surfactants, surfactant compounds, builders, bleaching agents, bleach activators, enzymes, foam inhibitors, dyes and - in the event that the surfactant-containing preparations are at least partly as moldings available - binding and disintegration aids. These classes of substances are described below.

To develop the washing performance, the surfactant-containing preparations according to the invention can contain surface-active substances from the group of anionic, nonionic, zwitterionic or cationic surfactants, anionic surfactants being clearly preferred for economic reasons and on the basis of their performance spectrum.

For example, anionic surfactants of the sulfonate and sulfate type are used. Suitable surfactants of the sulfonate type are preferably Cg.-13 alkyl benzene sulfonates, olefin sulfonates, ie mixtures of alkene and hydroxyalkanesulfonates and also disulfonates, as obtained, for example, from C _12-i ₈ monoolefins with an internal or terminal double bond by Sulfonation with gaseous sulfur trioxide and subsequent alkaline or acid hydrolysis of the sulfonation products is obtained. Also suitable are alkanesulfonates obtained from C _2-18 alkanes, for example by sulfochlorination or sulfoxidation with subsequent hydrolysis or neutralization. The esters of 2-sulfofatty acids (ester sulfonates), for example the 2-sulfonated methyl esters of hydrogenated coconut, palm kernel or tallow fatty acids, are also suitable.

Other suitable anionic surfactants are sulfated fatty acid glycerol esters. Fatty acid glycerol esters are to be understood as the mono-, di- and triesters as well as their mixtures as they are produced by esterification of a mono- glycerol with 1 to 3 moles of fatty acid or in the transesterification of triglycerides with 0.3 to 2 moles of glycerol can be obtained. Preferred sulfated fatty acid glycerol esters are the sulfonation products of saturated fatty acids having 6 to 22 carbon atoms, for example caproic acid, caprylic acid, capric acid, myristic acid, lauric acid, palmitic acid, stearic acid or behenic acid.

As alk (en) yl sulfates are the alkali and in particular the sodium salts of the sulfuric acid semiesters of the C ₂ -C ₈ fatty alcohols, for example from coconut fatty alcohol, tallow fatty alcohol, lauryl, myristyl, cetyl or stearyl alcohol or the C ₁ -C ₂ o-oxo alcohols and those half-esters of secondary alcohols of this chain length are preferred. Also preferred are alk (en) yl sulfates of the chain length mentioned which contain a synthetic, straight-chain alkyl radical prepared on a petrochemical basis and which have a degradation behavior analogous to that of the adequate compounds based on oleochemical raw materials. The Ci ₂ -C ₆ alkyl sulfates and C ^ -C ^ alkyl sulfates and C ₄ -C ₁₅ alkyl sulfates are preferred for washing technology reasons. In addition, 2,3-alkyl sulfates, which are produced for example in accordance with US Patent No. 3,234,258 or 5,075,041 and can be obtained as commercial products from Shell Oil Company under the name DAN ^®, are suitable anionic surfactants.

Also, the Schwefelsäuremonoester of linear or branched C ethoxylated with 1 to 6 mol ethylene oxide ₇ - ₂ i-alcohols such as 2-methyl-branched Cg-n-alcohols containing on average 3.5 mol ethylene oxide (EO) or Cι ₂ -i ₈ -Fatty alcohols with 1 to 4 EO are suitable. Because of their high foaming behavior, they are used in cleaning agents only in relatively small amounts, for example in amounts of 1 to 5% by weight.

Other suitable anionic surfactants are also the salts of alkylsulfosuccinic acid, which are also known as sulfosuccinates or as sulfosuccinic acid esters, and the monoesters and / or diesters of sulfosuccinic acid with alcohols, preferably fatty alcohols and especially ethoxylated fatty acids. represent alcohols. Preferred sulfosuccinates contain Cβ-iβ fatty alcohol residues or mixtures thereof. Particularly preferred sulfosuccinates contain a fatty alcohol residue which is derived from ethoxylated fatty alcohols, which in themselves are nonionic surfactants (description see below). Again, sulfosuccinates whose fatty alcohol residues are derived from ethoxylated fatty alcohols with a narrow homolog distribution are particularly preferred. It is also possible to use alk (en) ylsuccinic acid with preferably 8 to 18 carbon atoms in the alk (en) yl chain or salts thereof.

Soaps are particularly suitable as further anionic surfactants. Saturated fatty acid soaps are suitable, such as the salts of lauric acid, myristic acid, palmitic acid, stearic acid, hydrogenated erucic acid and behenic acid, and in particular from natural fatty acids, e.g. Coconut, palm kernel or tallow fatty acids, derived soap mixtures.

The anionic surfactants, including the soaps, can be in the form of their sodium, potassium or ammonium salts and also as soluble salts of organic bases, such as mono-, di- or triethanolamine. The anionic surfactants are preferably in the form of their sodium or potassium salts, in particular in the form of the sodium salts. In a further embodiment of the invention, surfactants are used in the form of their magnesium salts.

In the context of the present invention, surfactant-containing preparations are preferred which each contain 5 to 50% by weight, preferably 7.5 to 40% by weight and in particular 15 to 25% by weight, of one or more anionic surfactant (s) based on the surfactant-containing preparation.

When selecting the anionic surfactants that are used in the surfactant-containing preparations according to the invention, there are no restrictions to be observed in the freedom of formulation. Preferred surfactant Preparations according to the invention, however, have a soap content which exceeds 0.2% by weight, based on the total weight of the surfactant-containing preparation. The preferred anionic surfactants are the alkylbenzenesulfonates and fatty alcohol sulfates, preferred surfactant-containing preparations being 2 to 20% by weight, preferably 2.5 to 15% by weight and in particular 5 to 10% by weight of fatty alcohol sulfate (s), each based on the weight of the present surfactant-containing preparation according to the invention

The nonionic surfactants used are preferably alkoxylated, advantageously ethoxylated, in particular primary alcohols having preferably 8 to 18 carbon atoms and an average of 1 to 12 moles of ethylene oxide (EO) per mole of alcohol, in which the alcohol radical can be linear or preferably methyl-branched in the 2-position or may contain linear and methyl-branched radicals in the mixture, as are usually present in oxo alcohol radicals. However, alcohol ethoxylates with linear residues of alcohols of native origin with 12 to 18 carbon atoms, for example from coconut, palm, tallow or oleyl alcohol, and an average of 2 to 8 EO per mole of alcohol are particularly preferred. The preferred ethoxylated alcohols include, for example, -C ₂ alcohols with 3 EO or 4 EO, C _9-11 alcohol with 7 EO, C ₃ - ₅ alcohols with 3 EO, 5 EO, 7 EO or 8 EO, Cι ₂ -i ₈ alcohols with 3 EO, 5 EO or 7 EO and mixtures of these, and mixtures of Cι _2- ι ₄ alcohol with 3 EO and Cι _2-18 alcohol with 5 EO. The degrees of ethoxylation given represent statistical averages, which can be an integer or a fraction for a specific product. Preferred alcohol ethoxylates have a narrow homolog distribution (narrow range ethoxylates, NRE). In addition to these nonionic surfactants, fatty alcohols with more than 12 EO can also be used. Examples of this are tallow fatty alcohol with 14 EO, 25 EO, 30 EO or 40 EO.

Another class of preferred nonionic surfactants that are used either as the sole nonionic surfactant or in combination with other nonionic surfactants are alkoxylated, preferably ethoxy lated or ethoxylated and propoxylated fatty acid alkyl esters, preferably having 1 to 4 carbon atoms in the alkyl chain, in particular fatty acid methyl esters, as described, for example, in Japanese patent application JP 58/217598 or preferably according to that described in international patent application WO-A-90/13533 Process are made.

Another class of nonionic surfactants that can be used advantageously are the alkyl polyglycosides (APG). Alkypolyglycosides that can be used satisfy the general formula RO (G) _z , in which R represents a linear or branched, in particular methyl-branched, saturated or unsaturated, aliphatic radical having 8 to 22, preferably 12 to 18, C atoms and G is Is symbol which stands for a glycose unit with 5 or 6 carbon atoms, preferably for glucose. The degree of glycosidation z is between 1.0 and 4.0, preferably between 1.0 and 2.0 and in particular between 1.1 and 1.4.

Linear alkyl polyglucosides, ie alkyl polyglycosides, in which the polyglycosyl radical is a glucose radical and the alkyl radical is an n-alkyl radical are preferably used.

The surfactant-containing preparations according to the invention can preferably contain alkyl polyglycosides, with APG contents of more than 0.2% by weight, based on the preparation as a whole, being preferred for washing, rinsing or cleaning purposes. Particularly preferred surfactant-containing preparations contain APG in amounts of 0.2 to 10% by weight, preferably in amounts of 0.2 to 5% by weight and in particular in amounts of 0.5 to 3% by weight.

Nonionic surfactants of the amine oxide type, for example N-coconut alkyl-N, N-dimethylamine oxide and N-tallow alkyl-N, N-dihydroxyethylamine oxide, and the fatty acid alkanolamides can also be suitable. The amount of this non- Ionic surfactants are preferably not more than that of the ethoxylated fatty alcohols, in particular not more than half of them.

Other suitable surfactants are polyhydroxy fatty acid amides of the formula (II),

I R-CO-N- [Z] (II)

in which RCO stands for an aliphatic acyl radical with 6 to 22 carbon atoms, R ^ for hydrogen, an alkyl or hydroxyalkyl radical with 1 to 4 carbon atoms and [Z] for a linear or branched polyhydroxyalkyl radical with 3 to 10 carbon atoms and 3 to 10 hydroxyl groups. The polyhydroxy fatty acid amides are known substances which can usually be obtained by reductive amination of a reducing sugar with ammonia, an alkylamine or an alkanolamine and subsequent acylation with a fatty acid, a fatty acid alkyl ester or a fatty acid chloride.

The group of polyhydroxy fatty acid amides also includes compounds of the formula (III)

R ⁵ -OR ⁶

I

R-CO-N- [Z] (III)

in which R represents a linear or branched alkyl or alkenyl radical having 7 to 12 carbon atoms, R ^{5 represents} a linear, branched or cyclic alkyl radical or an aryl radical having 2 to 8 carbon atoms and R ^{6 represents} a linear, branched or cyclic alkyl radical or an aryl radical or an oxy- Alkyl radical having 1 to 8 carbon atoms, where or phenyl radicals are preferred and [Z] stands for a linear polyhydroxyalkyl radical, the alkyl chain of which is substituted with at least two hydroxyl groups, or alkoxylated, preferably ethoxylated or propylated, derivatives of this radical.

[Z] is preferably obtained by reductive amination of a reduced sugar, for example glucose, fructose, maltose, lactose, galactose, mannose or xylose. The N-alkoxy- or N-aryloxy-substituted compounds can then be converted, for example according to the teaching of international application WO-A-95/07331, by reaction with fatty acid methyl esters in the presence of an alkoxide as catalyst into the desired polyhydroxy fatty acid amides.

It may furthermore be preferred to use cationic surfactants in addition to anionic and nonionic surfactants. They are preferably used as washing performance boosters, whereby only small amounts of cationic surfactants are required. If cationic surfactants are used, they are preferably present in the preparations in amounts of from 0.01 to 10% by weight, in particular from 0.1 to 3.0% by weight.

In cases where the surfactant-containing preparations according to the invention are detergents, these usually contain one or more surfactant (s) in total amounts of 5 to 50% by weight, preferably in amounts of 10 to 35% by weight, partial or large portions of the preparations according to the invention may contain surfactants. In other words: the amount of surfactant is not the same in all portions; rather, partial portions with a relatively larger and partial portions with a relatively smaller surfactant content can be provided.

In cases in which the surfactant-containing preparations according to the invention are cleaning agents, in particular dishwashing agents, They usually contain one or more surfactant (s) in total amounts of 0.1 to 10% by weight, preferably in amounts of 0.5 to 5% by weight, surfactants in larger or smaller amounts in partial portions of the preparations according to the invention could be. In other words, the amount of surfactant is not the same in all portions, even with detergents or dishwashing detergents; rather, partial portions with a relatively larger and partial portions with a relatively smaller surfactant content can be provided.

In addition to the surfactants, builders are the most important ingredients in detergents and cleaning agents. The surfactant-containing preparations according to the invention can usually contain builders used in washing and cleaning agents, in particular thus zeolites, silicates, carbonates, organic cobuilders and - where there are no ecological prejudices against their use - the phosphates.

Suitable crystalline, layered sodium silicates have the general formula NaMSi _x O ₂ + ι 'H ₂ O, where M is sodium or hydrogen, x is a number from 1, 9 to 4 and y is a number from 0 to 20 and preferred values for x 2, 3 or 4. Such crystalline layered silicates are described, for example, in European patent application EP-A-0 164 514. Preferred crystalline layered silicates of the formula given are those in which M represents sodium and x assumes the values 2 or 3. In particular, both β- and δ-sodium disilicate Na ₂ Si ₂ O ₅ - yH ₂ O are preferred, with β-sodium disilicate being able to be obtained, for example, by the process described in international patent application WO-A-91/08171.

Amorphous sodium silicates with a Na ₂ O: SiO ₂ modulus of 1: 2 to 1: 3.3, preferably 1: 2 to 1: 2.8 and in particular 1: 2 to 1: 2.6, can also be used are delayed in dissolving and have secondary washing properties. The dissolution delay compared to conventional amorphous sodium silicates can be done in different ways, for example by surface treatment, compounding, compacting / compression or caused by overdrying. In the context of this invention, the term “amorphous” is also understood to mean “X-ray amorphous”. This means that the silicates in X-ray diffraction experiments do not provide sharp X-ray reflections, as are typical for crystalline substances, but at most one or more maxima of the scattered X-rays, which have a width of several degree units of the diffraction angle. However, it can very well lead to particularly good builder properties if the silicate particles deliver washed-out or even sharp diffraction maxima in electron diffraction experiments. This is to be interpreted as meaning that the products have microcrystalline areas of size 10 to a few hundred nm, values up to max. 50 nm and in particular up to max. 20 nm are preferred. Such so-called X-ray amorphous silicates, which also have a delay in dissolution compared to conventional water glasses, are described, for example, in German patent application DE-A-44 00 024. Compacted / compacted amorphous silicates, compounded amorphous silicates and over-dried X-ray amorphous silicates are particularly preferred.

An optionally used finely crystalline, synthetic and bound water-containing zeolite is preferably zeolite A and / or P. Zeolite P-type is particularly preferred as zeolite MAP (e.g. commercial product: Doucil A24 from Crosfield). However, zeolite X and mixtures of A, X and / or P are also suitable. Commercially available and can preferably be used in the context of the present invention, for example a co-crystallizate of zeolite X and zeolite A (about 80% by weight of zeolite X) ), which is sold by CONDEA Augusta SpA under the brand name VEGOBOND AX ^® and by the formula

nNa ₂ O ^• (1-n) K ₂ O ^• AI ₂ O ₃ ^• (2 - 2.5) SiO ₂ '(3.5 - 5.5) H ₂ O can be described. Suitable zeolites have an average particle size of less than 10 μm (volume distribution; measurement method: Coulter Counter) and preferably contain 18 to 22% by weight, in particular 20 to 22% by weight, of bound water.

It is of course also possible to use the generally known phosphates as builders in detergents, provided that such use should not be avoided for ecological reasons. The sodium salts of orthophosphates, pyrophosphates and in particular tripolyphosphates are particularly suitable.

Usable organic builders are, for example, the polycarboxylic acids which can be used in the form of their sodium salts, polycarboxylic acids being understood to mean those carboxylic acids which carry more than one acid function. For example, these are citric acid, adipic acid, succinic acid, glutaric acid, malic acid, tartaric acid, maleic acid, fumaric acid, sugar acids, aminocarboxylic acids, nitrilotriacetic acid (NTA), as long as their use is not objectionable for ecological reasons, and mixtures of these. Preferred salts are the salts of polycarboxylic acids such as citric acid, adipic acid, succinic acid, glutaric acid, tartaric acid, sugar acids and mixtures of these. The acids themselves can also be used. In addition to their builder action, the acids typically also have the property of an acidifying component and thus also serve to establish a lower and milder pH of surfactant-containing preparations according to the invention. In this context, citric acid, succinic acid, glutaric acid, adipic acid, gluconic acid and any mixtures of these should be mentioned in particular.

Polymeric polycarboxylates are also suitable as builders. These are, for example, the alkali metal salts of polyacrylic acid or polymethacrylic acid, for example those with a molecular weight of 500 to 70,000 g / mol.

In the context of the present invention, the molar masses given for polymeric polycarboxylates are weight-average molar masses M _{w of} the particular acid form, which were determined in principle by means of gel permeation chromatography (GPC), a UV detector being used. The measurement was made against an external polyacrylic acid standard, which provides realistic molecular weight values due to its structural relationship to the polymers investigated. This information differs significantly from the molecular weight information for which polystyrene sulfonic acids are used as standard. The molecular weights measured against polystyrene acids are generally significantly higher than the molecular weights specified in the context of the present invention.

Suitable polymers are, in particular, polyacrylates, which preferably have a molecular weight of 2,000 to 20,000 g / mol. Because of their superior solubility, the short-chain polyacrylates with molecular weights of 2,000 to 10,000 g / mol, particularly preferably 3,000 to 5,000 g / mol, can in turn be preferred from this group.

Also suitable are copolymeric polycarboxylates, in particular those of acrylic acid with methacrylic acid or of acrylic acid or methacrylic acid with maleic acid. Copolymers of acrylic acid with maleic acid which contain 50 to 90% by weight of acrylic acid and 50 to 10% by weight of maleic acid have proven to be particularly suitable. Their relative molar mass, based on free acids, is generally 2,000 to 70,000 g / mol, preferably 20,000 to 50,000 g / mol and in particular 30,000 to 40,000 g / mol.

The (co) polymeric polycarboxylates can be used either as a powder or as an aqueous solution. The content of the surfactant-containing The preparation of (co) polymeric polycarboxylates is preferably 0.5 to 20% by weight, in particular 3 to 10% by weight.

To improve water solubility, the polymers can also contain allylsulfonic acids, such as, for example, in EP-B 0 727 448, allyloxybenzenesulfonic acid and methallylsulfonic acid as a monomer.

Also particularly preferred are biodegradable polymers composed of more than two different monomer units, for example those which, according to DE-A 43 00 772, are salts of acrylic acid and maleic acid as well as vinyl alcohol or vinyl alcohol derivatives or according to DE-C 42 21 381 contain as monomers salts of acrylic acid and 2-alkylallylsulfonic acid and sugar derivatives.

Further preferred copolymers are those described in German patent applications DE-A 43 03 320 and DE-A 44 17 734 and preferably contain acrolein and acrylic acid / acrylic acid salts or acrolein and vinyl acetate as monomers.

Also to be mentioned as further preferred builder substances are polymeric aminodicarboxylic acids, their salts or their precursor substances. Particularly preferred are polyaspartic acids or their salts and derivatives, of which it is disclosed in German patent application DE-A 195 40 086 that, in addition to co-builder properties, they also have a bleach-stabilizing effect.

Further suitable builder substances are polyacetals which can be obtained by reacting dialdehydes with polyolcarboxylic acids which have 5 to 7 carbon atoms and at least 3 hydroxyl groups, for example as described in European patent application EP-A 0 280 223. Preferred polyacetals are derived from dialdehydes such as glyoxal, Glutaraldehyde, te Rephthalaldehyde and mixtures thereof and from polyol carboxylic acids such as gluconic acid and / or glucoheptonic acid.

Other suitable organic builder substances are dextrins, for example oligomers or polymers of carbohydrates, which can be obtained by partial hydrolysis of starches. The hydrolysis can be carried out by customary processes, for example acid-catalyzed or enzyme-catalyzed. They are preferably hydrolysis products with average molecular weights in the range from 400 to 500,000 g / mol. A polysaccharide with a dextrose equivalent (DE) in the range from 0.5 to 40, in particular from 2 to 30, is preferred, DE being a customary measure of the reducing action of a polysaccharide compared to dextrose, which is a DE of 100 owns. Both maltodextrins with a DE between 3 and 20 and dry glucose syrups with a DE between 20 and 37 as well as so-called yellow dextrins and white dextrins with higher molar masses in the range from 2,000 to 30,000 g / mol can be used. A preferred dextrin is described in British patent application 94 19 091.

The oxidized derivatives of such dextrins are their reaction products with oxidizing agents which are capable of oxidizing at least one alcohol function of the saccharide ring to the carboxylic acid function. Such oxidized dextrins and processes for their preparation are known in particular from European patent applications EP-A 0 232 202, EP-A 0 427 349, EP-A 0 472 042 and EP-A 0 542 496 and from international patent applications WO 92/18542 , WO 93/08251, WO 93/16110, WO 94/28030, WO 95/07303, WO 95/12619 and WO 95/20608. An oxidized oligosaccharide according to German patent application DE-A 196 00 018 is also suitable. A product oxidized to Co of the saccharide ring can be particularly advantageous. Oxydisuccinates and other derivatives of disuccinates, preferably ethylenediamine disuccinate, are further suitable co-builders. Ethylene diamine N, N'-disuccinate (EDDS), the synthesis of which is described, for example, in US Pat. No. 3,158,615, is preferably used in the form of its sodium or magnesium salts. Also preferred in this context are glycerol disuccinates and glycerol trisuccinates, as described, for example, in US Pat. Nos. 4,524,009 and 4,639,325, in European patent application EP-A 0 150 930 and in Japanese patent application JP-A 93 / 339,896 to be discribed. Suitable amounts for use in formulations containing zeolite and / or silicate are 3 to 15% by weight.

Other useful organic co-builders are, for example, acetylated hydroxycarboxylic acids or their salts, which may also be present in lactone form and which contain at least 4 carbon atoms and at least one hydroxyl group and a maximum of two acid groups. Such co-builders are described, for example, in international patent application WO 95/20029.

Another class of substances with Co-Bu / Ider properties are the phosphonates. These are in particular hydroxyalkane or aminoalkanephosphonates. Among the hydroalkane phosphonates, 1-hydroxyethane-1,1-diphosphonate (HEDP) is of particular importance as a co-builder. It is preferably used as the sodium salt, the disodium salt reacting neutrally and the tetrasodium salt alkaline (pH = 9). Preferred aminoalkane phosphonates are ethylenediaminetetramethylenephosphonate (EDTMP), diethylenetriaminepentamethylenephosphonate (DTPMP) and their higher homologs. They are preferably used in the form of the neutral-reacting sodium salts, for example as the hexasodium salt of EDTMP or as the hepta- and octasodium salt of DTPMP. HEDP is preferably used as the builder from the class of the phosphonates. The aminoal Kanphosphonates also have a strong ability to bind heavy metals. Accordingly, in particular if the surfactant-containing preparations according to the invention also contain bleach, it may be preferred to use aminoalkane phosphonates, in particular DTPMP, or to use mixtures of the phosphonates mentioned.

In addition, all compounds that are able to form complexes with alkaline earth metal ions can be used as co-builders.

In addition to the surfactant and builder constituents mentioned, the surfactant-containing preparations according to the invention can, in particular as detergents or cleaning agents, include other ingredients from the group of bleaching agents, bleach activators, enzymes, fragrances, perfume carriers, fluorescent agents, dyes, foam inhibitors, silicone oils, antireflective detergents or detergents. contain deposition agents, optical brighteners, graying inhibitors, color transfer inhibitors and corrosion inhibitors.

Among the compounds which serve as bleaching agents and supply H ₂ O ₂ in water, sodium perborate tetrahydrate and sodium perborate monohydrate are of particular importance. Other bleaching agents which can be used are, for example, sodium percarbonate, peroxypyrophosphates, citrate perhydrates and H ₂ O ₂ -producing peracidic salts or peracids, such as perbenzoates, peroxophthalates, diperazelaic acid, phthaloiminoperacid or diperdodecanedioic acid. If cleaning or bleaching preparations for machine dishwashing are produced, bleaching agents from the group of organic bleaching agents can also be used. Typical organic bleaching agents are the diacyl peroxides, such as dibenzoyl peroxide. Other typical organic bleaching agents are peroxy acids, examples of which include alkyl peroxy acids and aryl peroxy acids. Preferred representatives are (a) peroxybenzoic acid and its ring-substituted derivatives, such as alkylperoxybenzoic acids, but also peroxy-α-naphthoic acid and magnesium monoper phthalate; (b) the aliphatic or substituted aliphatic peroxy acids, such as peroxylauric acid, peroxystearic acid, ε-phthalimidoperoxy-caproic acid [phthaloiminoperoxyhexanoic acid (PAP)], o-carboxybenzamido-per-oxycaproic acid, N-nonenylamido operadipic acid and N-succinate; and (c) aliphatic and araliphatic peroxydicarboxylic acids, such as 1, 12-diperoxycarboxylic acid, 1, 9-diperoxyazelaic acid, diperocysebacic acid, diperoxybrassyl acid, the diperoxyphthalic acids, 2-decyldiperoxybutane-1, 4-diacid, N, N-di-terephthaloylophenoyl ) can be used.

Chlorine or bromine-releasing substances can also be used as bleaching agents in compositions for machine dishwashing. Suitable chlorine or bromine-releasing materials include, for example, heterocyclic N-bromo- and N-chloramides, for example trichloroisocyanuric acid, tribromoisocyanuric acid, dibromoisocyanuric acid and / or dichloroisocyanuric acid (DICA) and / or their salts with cations such as potassium and sodium. Hydantoin compounds such as 1,3-dichloro-5,5-dimethylhydantoin are also suitable.

In order to achieve an improved bleaching effect when washing or cleaning at temperatures of 60 ° C. and below, bleach activators can be incorporated into the surfactant-containing preparations. Bleach activators which can be used are compounds which, under perhydrolysis conditions, give aliphatic peroxocarboxylic acids having preferably 1 to 10 C atoms, in particular 2 to 4 C atoms, and / or optionally substituted perbenzoic acid. Suitable substances are those which carry O- and / or N-acyl groups of the number of carbon atoms mentioned and / or optionally substituted benzoyl groups. Preferred are multiply acylated alkylenediamines, in particular tetraacetylethylenediamine (TAED), acylated triazine derivatives, in particular 1,5-diacetyl-2,4-dioxohexahydro-1,3,5-triazine (DADHT), acylated glycolurils, in particular tetraacetylglycoluril (TAGU), N- Acylimides, especially N-nonanoyl succinimide (NOSl), acylated phenolsulfonates, especially n-nonanoyl- or isononanoyloxybenzenesulfonate (n- or iso-NOBS), carboxylic acid anhydrides, especially phthalic anhydride, acylated polyhydric alcohols, especially triacetin, ethylene glycol diacetate and 2,5-diacetoxy-2,5-di-acetoxy ,

In addition to the conventional bleach activators or in their place, so-called bleach catalysts can also be incorporated into the surfactant-containing preparations. These substances are bleach-enhancing transition metal salts or transition metal complexes such as, for example, Mn, Fe, Co, Ru or Mo salt complexes or carbonyl complexes. Mn, Fe, Co, Ru, Mo, Ti, V and Cu complexes with N-containing tripod ligands as well as Co, Fe, Cu and Ru amine complexes can also be used as bleaching catalysts.

Suitable enzymes are those from the class of proteases, lipases, amylases, cellulases or mixtures thereof. Enzymes obtained from bacterial strains or fungi such as Bacillus subtilis, Bacillus licheniformis and Streptomyces griseus are particularly suitable. Proteases of the subtilisin type and in particular proteases which are obtained from Bacillus lentus are preferably used. Enzyme mixtures, for example of protease and amylase or protease and lipase or proteases and cellulase or of cellulase and lipase or of protease, amylase and lipase or protease, lipase and cellulase, but in particular mixtures containing cellulase, are of particular interest. Peroxidases or oxidases have also proven to be suitable in some cases. The enzymes can be adsorbed on carriers and / or embedded in coating substances in order to protect them against premature decomposition. The proportion of enzymes, enzyme mixtures or enzyme granules in the surfactant-containing preparations according to the invention can be, for example, about 0.1 to 5% by weight, preferably 0.1 to about 2% by weight. According to a particularly preferred embodiment, the surfactant-containing preparations according to the invention also contain further additives as are known from the prior art as additives for detergent or cleaning agent preparations. These can either be added to one or more portions of the surfactant-containing preparations according to the invention or, if necessary, to all partial portions (detergent-active preparations) or - as described in the copending patent application No. 199 29 098.9 entitled "Active ingredient portion pack" - in water-soluble, the materials comprising detergent formulations, for example in water-soluble films, but also in capsules or coatings which can be used according to the invention, are incorporated.

A preferred group of additives used according to the invention are optical brighteners. The optical brighteners customary in detergents can be used here. These are added as an aqueous solution or as a solution in an organic solvent to the polymer solution which is converted into the film, or are added to a portion (detergent-active preparation) of a detergent or cleaning agent in solid or liquid form. Examples of optical brighteners are derivatives of diaminostilbenedisulfonic acid or its alkali metal salts. Are suitable for. B. salts of 4, 4'-bis (2-anilino-4-morpholinol, 3,5-triazinyl-6-amino-) stilbene-2,2'-disulfonic acid or compounds of similar structure, which instead of the morpholino group a Diethanolamino group, a methylamino group, an anilino group or a 2-methoxyethylamino group. Furthermore, brighteners of the type of the substituted diphenylstyryl can be contained in the partial portions (detergent preparations) of the surfactant-containing preparations according to the invention, e.g. B. the alkali salts of 4,4'-bis (2-sulfostyryl-) diphenyl, 4,4'-bis (4-chloro-3-sulfostyryl-) diphenyl or 4- (4-chlorostyryl-) 4 '- (2nd -sulfostyryl-) biphenyl. Mixtures of the aforementioned brighteners can also be used. Another group of additives preferred according to the invention are UV protection substances. These are substances which are released in the washing liquor during the washing process or during the subsequent fabric softening process and which accumulate on the fiber in order to then achieve a UV protection effect. Products from Ciba Specialty Chemicals that are commercially available under the name Tinosorb are suitable.

Another group of additives preferred according to the invention are dyes, in particular water-soluble or water-dispersible dyes. Dyes are preferred here, as are usually used to improve the optical product appearance in washing, rinsing, cleaning and finishing agents. The choice of such dyes does not pose any difficulties for the person skilled in the art, in particular since such customary dyes have a high storage stability and insensitivity to the other ingredients of the detergent preparations and to light, and have no pronounced substance towards textile fibers, in order not to dye them. According to the invention, the dyes are present in the surfactant-containing preparations according to the invention in amounts of less than 0.01% by weight.

Another class of additives that can be added to the surfactant-containing preparations according to the invention are polymers. Among these polymers are, on the one hand, polymers which show cobuilder properties during washing or cleaning or rinsing, for example polyacrylic acids, also modified polyacrylic acids or corresponding copolymers. Another group of polymers are polyvinylpyrrolidone and other graying inhibitors, such as copolymers of polyvinylpyrrolidone, cellulose ether and the like. According to a further embodiment of the invention, so-called soil repellents, as are known to the person skilled in the detergent and cleaning agent and are described in detail below, are also suitable as polymers. Another group of additives are bleaching catalysts, in particular bleaching catalysts for automatic dishwashing detergents or detergents. Complexes of manganese and cobalt are used here, especially with nitrogen-containing ligands.

Another preferred group of additives in the sense of the invention are silver protection agents. These are a large number of mostly cyclic organic compounds which are likewise familiar to the person skilled in the art and which help to prevent tarnishing of silver-containing objects during the cleaning process. Specific examples can be triazoles, benzotriazoles and their complexes with metals such as Mn, Co, Zn, Fe, Mo, W or Cu.

As further additives according to the invention, the surfactant-containing preparations can also contain so-called soil repellents, that is to say polymers which build up on fibers or hard surfaces (for example on porcelain and glass), have a positive influence on the oil and fat washability from textiles and thus counteract any soiling in a targeted manner , This effect is particularly evident when a textile or a hard object (porcelain, glass) is soiled that has already been washed several times beforehand with a washing or cleaning agent according to the invention which contains this oil and fat-dissolving component. The preferred oil and fat-dissolving components include, for example, nonionic cellulose ethers such as methyl cellulose and methyl hydroxypropyl cellulose with a proportion of methoxy groups of 15 to 30% by weight and of hydroxypropoxy groups of 1 to 15% by weight, based in each case the nonionic cellulose ether, and the polymers of phthalic acid and / or terephthalic acid or their derivatives known from the prior art, in particular polymers of ethylene terephthalates and / or polyethylene glycol terephthalates or anionically and / or nonionically modified derivatives thereof. Of these, the sulfonated derivatives of phthalic acid and terephthalic acid polymers are particularly preferred. All of these additives are added to the surfactant-containing preparations according to the invention in amounts of at most 30% by weight, preferably 2 to 20% by weight. As already mentioned, the addition can also be made to a material of a water-soluble enclosure, which comprises one or more of the washing-active preparations. In order to maintain the balance of the recipe, it is therefore possible for a person skilled in the art to either increase the weight of the plastic material for the enclosure, in order to exploit the depot effect which is achieved according to the invention, or to add at least some of the additives mentioned to keep the rest of the active detergent preparation. However, this is less preferred.

This list of detergent and cleaning agent ingredients, which can occur in the surfactant-containing preparations according to the invention, provided they are detergents, dishwashing detergents or cleaning agents, is by no means exhaustive, but merely reflects the essential typical ingredients of such agents. In particular, as far as liquid or gel preparations are concerned, organic solvents can also be contained in the agents. It is preferably monohydric or polyhydric alcohols having 1 to 4 carbon atoms. Preferred alcohols in such agents are ethanol, 1, 2-propanediol, glycerol and mixtures of these alcohols. In preferred embodiments, such agents contain 2 to 12% by weight of such alcohols.

Preparations according to the invention can also be cosmetic preparations which differ in their composition from washing, rinsing, cleaning and finishing agents as described above. In particular, this applies to non-surfactant-containing cosmetic preparations according to the present invention. However, the invention also includes surfactant-containing cosmetic preparations. These cosmetic compositions preferably contain alkoxylated fragrance alcohols of the formula (I) in an amount of 0.001 to 10% by weight, preferably in an amount of 0.01 to 5% by weight, particularly preferably preferably in an amount of 0.02 to 3 and in particular in an amount of 0.05 to 2% by weight, in each case based on the cosmetic agent.

In a preferred embodiment, the cosmetic agents are aqueous preparations which may contain surfactants or surface-active substances and which are particularly suitable for the treatment of keratin fibers, in particular human hair, or for the treatment of human skin.

Fatty alcohol polyglycol ether sulfates (ether sulfates, alkyl ether sulfates) are predominantly used for the most important group of ingredients, the surface-active (surfactant) active ingredients or detergent active ingredients, in some cases in combination with other, usually anionic, surfactants. In addition to good cleaning power and insensitivity to water hardness, shampoo surfactants should be compatible with the skin and mucous membranes. According to the legal regulations, there should be good biodegradability. In addition to the alkyl ether sulfates, preferred agents may additionally contain further surfactants, such as alkyl sulfates, alkyl ether carboxylates, preferably with degrees of ethoxylation of 4 to 10, and surfactant protein-fatty acid condensates. The protein-abietic acid condensate deserves special mention here. Sulfosuccinic acid esters, amidopropyplbetaines, amphoacetates and amphodiacetates as well as alkyl polyglycosides are also preferred surfactants used in hair shampoos.

Another group of ingredients is summarized under the term auxiliaries and is very diverse: For example, additions of non-ionic surfactants such as ethoxylated sorbitan esters or protein hydrolysates increase the tolerance or have an irritant effect, eg. B. in baby shampoos; serve as moisturizers to prevent excessive degreasing when washing hair, e.g. B. natural oils or synthetic fatty acid esters; Glycerin, sorbitol, propylene glycol (see propanediols), polyethylene glycols and other polyols serve as humectants. To improve wet combability and reduction of electrostatic charge on the hair after drying can shampoo the cationic surfactants such. B. Quaternary ammonium compounds can be added. Dyes or pearlescent pigments are added for a colored, brilliant appearance. Thickeners of different substance classes can be used to adjust the desired viscosity. B. achieved on the basis of citrate, lactate or phosphate. In order to ensure sufficient durability and shelf life, preservatives such as. B. 4-hydroxybenzoic acid ester added; Oxidation-sensitive ingredients can be protected by adding antioxidants such as ascorbic acid, butyl methoxyphenol or tocopherol.

A third group of ingredients form special active ingredients for special shampoos, e.g. B. oils, herbal extracts, proteins, vitamins and lecithins in shampoos for quickly greasing, for particularly dry, for damaged or damaged hair. Active ingredients in shampoos to combat dandruff usually have a broad growth-inhibiting effect against fungi and bacteria. In particular, the fungistatic properties such. B. of pyrithione salts could be proven as the cause of good anti-dandruff effect. The hair shampoos contain perfume oils to create a pleasant fragrance. The shampoos can exclusively contain the alkoxylated fragrance alcohols according to the invention; however, it is also preferred if the hair shampoos contain not only these but also other fragrances. All the usual fragrances approved in hair shampoos can be used.

The aim of hair care products is to maintain the natural state of freshly regrown hair for as long as possible and to restore it if it is damaged. Features that characterize this natural state are silky sheen, low porosity, resilient yet soft fullness and pleasantly smooth feeling. An important requirement for this is a clean, dandruff-free and not over-greasy scalp. Today, hair care products include a large number of different products, the main representatives of which are referred to as pre-treatment agents, hair lotions, hairdressing aids, hair rinses and spa packs, and whose composition is roughly broken down into basic substances, auxiliary substances and special active substances, as is the case with hair detergents.

The basic ingredients are fatty alcohols, especially cetyl alcohol (1-hexadecanol) and stearyl alcohol (1-octadecanol), waxes such as beeswax, wool wax (lanolin), wax and synthetic waxes, paraffins, petroleum jelly, paraffin oil and, above all, solvents, ethanol, 2-propanol and water. Excipients are emulsifiers, thickeners, preservatives, antioxidants, dyes and perfume oils. The most important group of special active ingredients in hair care products today are the quaternary ammonium compounds. A distinction is made between monomeric (e.g. alkyltrimethylammonium halide with especially the lauryl, cetyl or stearyl group as the alkyl radical) and polymeric quaternary ammonium compounds [e.g. E.g .: quaternary cellulose ether derivatives or poly (N, N-dimethyl-3,4-methylene pyrrolidinium chloride)]. Their effect in hair care products is based on the fact that the positive charge of the nitrogen atoms of this compound can attach to the negative charges of the hair keratin; Damaged hair contains more negatively charged acid groups due to its higher cysteic acid content and can therefore absorb more quaternary ammonium compounds. These, also referred to as “cation-active care substances” because of their cation-active character, have a smoothing effect on the hair, improve combability, reduce electrostatic charging, improve grip and shine. The polymeric quaternary ammonium compounds adhere so well to the hair that their action is still effective after several washes. Organic acids such as citric acid, tartaric acid or lactic acid are often used to adjust an acidic environment. The water-soluble protein hydrolysates are well absorbed by the hair keratin due to their close chemical relationship. The largest group of special active ingredients in hair care products form various plant extracts and plant Oils that have mostly been used for a long time without their effectiveness on the advertised effect has been scientifically proven in all cases. Likewise, the effectiveness of vitamins used in hair care products has only been proven in individual cases. To avoid re-greasing too quickly, some hair lotions contain substances such as certain tar ingredients, cysteic acid derivatives or glycyrrhizin; the intended reduction in sebum production has also not yet been clearly proven. On the other hand, the effectiveness of anti-dandruff agents has been proven perfectly. They are therefore used in appropriate hair lotions including care products.

The aqueous preparations for the treatment of skin are in particular preparations for the care of human skin. This care begins with the cleaning for which soaps are primarily used. A distinction is made between solid, mostly lumpy and liquid soap. Accordingly, in a preferred embodiment, the cosmetic preparations are in the form of moldings which contain surface-active (surfactant) ingredients. In a preferred embodiment, the most important constituents of such shaped articles are the alkali metal salts of the fatty acids of natural oils and fats, preferably with chains of 12 to 18 carbon atoms. Since lauric acid soaps foam particularly well, the lauric acid-rich coconut and palm kernel oils are preferred raw materials for fine soap manufacture. The Na salts of the fatty acid mixtures are solid, the K salts are soft-pasty. For saponification, the dilute sodium or potassium hydroxide solution is added to the fat raw materials in a stoichiometric ratio so that an excess of alkali in the finished soap of max. 0.05% is present. In many cases, soaps are no longer made directly from fats, but from the fatty acids obtained through fat splitting. Common soap additives are fatty acids, fatty alcohols, lanolin, lecithin, vegetable oils, partial glycerides and other fat-like substances for regreasing the cleansed skin, antioxidants such as ascorbyl palmitate or tocopherol to prevent the autoxidation of the soap (rancidity), complexing agents such as Nitrilotriacetate to bind traces of heavy metals that could catalyze autoxidative spoilage, perfume oils to achieve the desired fragrance notes, dyes to color the soap bars and, if necessary, special additives.

The most important types of fine soaps are:

- toilet soaps with 20 to 50% coconut oil in the fat mixture, up to 5% refatting agent and 0.5 to 2% perfume oil, they form the largest part of fine soaps;

- Luxury soaps with up to 5% z. T. particularly valuable perfume oils;

- Deodorant soaps with additives of deodorising agents, such as. B. 3,4,4'-trichlorocarbanilide (triclocarban);

- Cream soaps with particularly high proportions of lipid-replenishing substances that cream the skin;

- Baby soaps with good regreasing and additional nourishing components such as B. chamomile extracts, at most very slightly perfumed;

- Skin protection soaps with high proportions of moisturizing substances as well as other nourishing and protective additives such as B. proteins;

- Transparent soaps with additives of glycerin, sugar and. a., which prevent the crystallization of the fatty acid salts in the solidified soap melt and thus bring about a transparent appearance; Floating soaps with density <1, caused by air bubbles incorporated in a controlled manner during production.

Soaps can also contain abrasive additives for cleaning heavily soiled hands. When washing with soap, a pH value of 8 to 10 is set in the wash liquor. This alkalinity neutralizes the skin's natural acid coat (pH 5 to 6). This is regressed relatively quickly with normal skin, but irritation can occur with sensitive or damaged skin. Another disadvantage of soaps is their formation insoluble lime soaps in hard water. These disadvantages do not exist with Syndet soaps. They are based on synthetic anionic surfactants, which can be processed with soap substances, refatting agents and other additives into soap-like pieces. Their pH value can be varied within a wide range and is usually adjusted to pH 7 in a neutral manner or adjusted to pH 5.5 to suit the skin's acid coat. They have excellent cleaning power, foam in every water hardness, even in sea water, the proportion of lipid-replenishing additives must be significantly higher than with normal soaps due to their intensive cleaning and degreasing effect. Their disadvantage is the relatively high price.

Liquid soaps are based on both K salts of natural fatty acids and synthetic anionic surfactants. They contain less wash-active substances in aqueous solution than solid soaps, have the usual additives, optionally with viscosity-regulating components and pearlescent additives. Because of their convenient and hygienic use from dispensers, they are preferably used in public washrooms and the like. Wash lotions for particularly sensitive skin are based on mild-acting synthetic surfactants with additives of skin-care substances, pH neutral or slightly acidic (pH 5.5).

There are a number of other preparations for cleaning primarily the facial skin, such as facial tonics, cleaning lotions, milks, creams and pastes; Face packs are used e.g. T. the cleaning, but mostly the refreshment and care of the facial skin. Facial lotions are mostly aqueous-alcoholic solutions with low surfactant levels and other skin-care substances. Cleansing lotions, milks, creams and pastes are mostly based on O / W emulsions with relatively low levels of fat components with cleaning and care additives. So-called scruffing and peeling preparations contain mildly keratolytic substances to remove the top dead skin-hom layers, e.g. T. with additives abrasive powder. Which has long been used as a mild skin cleanser Even today, almond bran is still part of such preparations. Antibacterial and anti-inflammatory substances are also contained in cleansing treatments for blemished skin, since the sebum accumulation in comedones (blackheads) is a breeding ground for bacterial infections and tends to cause inflammation. The wide range of different skin cleansing products on offer varies in composition and content of various active ingredients, tailored to the different skin types and specific treatment goals.

The bath additives offered for skin cleaning in the bath or shower have found wide application. Bath salts and bath tablets are intended to soften, color and perfume the bathing water and generally do not contain any washing-active substances. By softening the bath water, they promote the cleaning power of soaps, but are primarily intended to have a refreshing effect and enhance the bathing experience. Bubble baths are of greater importance. With a higher content of lipid-replenishing and skin-care substances, one also speaks of cream baths.

In addition to bubble baths, shower baths have established themselves on the market since about 1970 and have exceeded their production volume since 1986. They are composed similarly to liquid shampoos, but contain special skin-care ingredients instead of hair-care agents. Combination products, suitable for skin and hair, have recently also appeared on the market.

The skin care that follows cleaning has two main goals: on the one hand, it should restore the skin's constituents, such as horny cells, skin lipids, acidifiers and water, which have been extracted in an uncontrolled manner, to the natural state of equilibrium; on the other hand, it should help the skin's natural aging process and possible damage counteract as much as possible by weather and environmental influences. Preparations for Skin care and skin protection are offered in large numbers and in many forms of preparation. The most important are skin creams, lotions, oils and skin gels. The basis of the creams and lotions are emulsions in O / W (oil in water) or W / O (water in oil) form. The main components of the oil, fat or lipid phase are fatty alcohols, fatty acids, fatty acid esters, waxes, petroleum jelly, paraffins and other fat and oil components of mainly natural origin. In addition to water, the aqueous phase mainly contains moisture-regulating and moisture-preserving substances as essential skin care active ingredients, and also consistency and viscosity-regulating agents. Other additives such as preservatives, antioxidants, complexing agents, perfume oils, colorants and special active ingredients are added to one of the two phases mentioned above depending on their solubility and their stability properties. The selection of the emulsifier system is essential for the type of emulsion and its properties. It can be selected according to the HLB system.

According to their area of application, the creams or lotions can be divided into "day creams" and "night creams". Day creams are mostly built up as O / W emulsions, they are quickly absorbed into the skin without leaving an oily sheen; they are therefore called z. T. also as dry creams, matt creams or vanishing creams. Night creams are mostly W / O emulsions, they are absorbed more slowly by the skin and often contain special active ingredients that are supposed to regenerate the skin during the night. Some of these preparations are also referred to as "nutritional creams", although "cell metabolism" in the skin can only be "nourished" via the bloodstream; the term "nutrient cream" is therefore controversial. So-called cold creams are mixed emulsions of the O / W and W / O type, with the oil phase predominating in quantity. With classic cold cream, the water, which in some cases was only unstably emulsified, was released during application and created a cooling effect through evaporation, which gave this preparation its name. The large number of special active ingredients used in the skin care products and the effects attributed to them cannot be discussed in detail here. Mention should be made of milk protein products, egg yolk, lecithins, lipoids, phosphatides, cereal germ oils, vitamins - in particular vitamin F and the biotin formerly known as skin vitamin (vitamin H) as well as hormone-free placenta extracts. Hormones that were sometimes used in the past are no longer used because they are classified as active pharmaceutical ingredients and may not be used in cosmetic products.

Skin oils are among the oldest forms of skin care products and are still used today. The basis is non-drying vegetable oils such as almond oil or olive oil, with additions of natural vitamin oils such as wheat germ oil or avocado oil as well as oily plant extracts from z. B. St. John's wort, chamomile u. The addition of antioxidants against rancidity is essential, desired fragrance notes are achieved by perfume oils, an addition of paraffin oil or liquid fatty acid esters serves to optimize the application properties.

Skin gels are semi-solid, transparent products that are stabilized by appropriate gel formers. A distinction is made between oleogels (water-free), hydrogels (oil-free) and oil / water gels. The type selection depends on the desired application. The oil / water gels contain high levels of emulsifier and have certain advantages over emulsions from both an aesthetic and application point of view.

Foot baths are said to have a good cleansing, refreshing, circulation-stimulating and invigorating effect, as well as deodorising and softening the cornea. Foot bath additives are available as bath salts and bubble baths. They exist e.g. B. from base mixtures of sodium carbonate, sodium hydrogen carbonate and sodium perborate or sodium hexametaphosphate, sodium sulfate, sodium perborate and 1% sodium lauryl sulfate as a foam component with antiperspirant, deodorant, optionally bactericidal and / or fungicidal additives and fragrance and Dyes. Foot powders, applied after shampooing and / or sprinkled in stockings and shoes, should have a smoothing, cooling, moisture-absorbing, antiperspirant, antiseptic, deodorising and, if necessary, softening callus. They generally consist of 85% talc with the addition of silicic acid powder, aluminum hydroxychloride, salicylic acid and possibly bactericides, fungicides, deodorants and fragrances. Foot creams or foot balms are used for skin care and for massaging the foot and lower leg muscles. Foot creams are usually O / W emulsions from z. B. 30% isopropyl myristate, 10% polysorbate, 4.2% aluminum metahydroxide and 55.8% water as the basic formulation; Foot balms are mostly water-free and. contain z. B. 85% petroleum jelly, 5% paraffin, 3% lanolin, 3% methyl salicylate, 2% camphor, 1% menthol and 1% eucalyptus oil. Corneal removing agents such as B. "Rubbing creams" are rubbed on the skin until the cornea is removed in the shape of a crumb. A frame formulation consists of 25% paraffin, 2% stearic acid, 2% beeswax, 2% walnut, 2% glycerol monostearate, 0.5% 2, 2 ', 2 "nitrilotriethanol, 1% perfume oil, 0.2% 4-hydroxybenzoic acid and 65.3% water. Nail fold tinctures are used to soften calluses in the nail folds and to keep the edges of the nails soft when the toenails grow in, mainly on the big toes. A frame formulation is made up of 10% 2,2 ', 2 "nitrilotriethanol, 15% urea, 0.5% fatty alcohol polyglycol ether and 74.5% water

Further cosmetic agents preferred according to the invention are agents for influencing body odor. In particular, deodorant agents are meant here. Such deodorants can mask, remove or destroy odors. Unpleasant body odors arise when bacteria sweat decompose, especially in the warm, moist armpits, where microorganisms find good living conditions. Accordingly, the main ingredients in deodorants are germ-inhibiting substances. In particular, those germ-inhibiting substances are preferred which have a largely selective activity compared to those responsible for body odor Own bacteria. However, preferred active ingredients only have a bacteriostatic effect and in no way completely kill the bacterial flora. In general, all suitable preservatives with a specific action against gram-positive bacteria can be directed to the germ-inhibiting agent. These are, for example, Irgasan DP 300 (trichlosan, 2,4,4'-trichloro-2'-hydroxydiphenyl ether), chlorhexidine (1, 1 '-hexamethylene bis (5- (4'-chloropheny!) - biguanide) and 3, 4,4'-trichlorocarbanilide. Quaternary ammonium compounds are also suitable in principle. Because of their high antimicrobial activity, all these substances are preferably used only in small concentrations of about 0.1 to 0.3% by weight numerous odoriferous substances also have antimicrobial properties. Accordingly, such odoriferous substances with antimicrobial properties are preferably used in deodorants. Farnesol and phenoxyethanol are particularly to be mentioned here. It is therefore particularly preferred if the deodorants according to the invention contain such themselves bacteriostatically active odoriferous substances. The odorous substances can preferably be in the form of fragrance alcohol alkoxylates, but it is also possible for antibacterial fragrances to be present together with Fragrance alcohol alkoxylates are used and are thus present in mixtures with other fragrances. Another group of essential ingredients of deodorants are enzyme inhibitors that inhibit the decomposition of sweat by enzymes, such as citric acid triethyl ester or zinc glycinate. The essential ingredients of deodorants are also antioxidants, which are intended to prevent oxidation of the sweat components.

In a further likewise preferred embodiment of the invention, the cosmetic agent is a hair setting agent which contains polymers for setting. It is particularly preferred if at least one polyurethane is contained among the polymers. In a preferred embodiment, the agents according to the invention can contain water-soluble polymers from the group of nonionic, anionic, amphoteric and zwitterionic polymers.

Water-soluble polymers are understood to be those polymers which are more than 2.5% by weight soluble in water at room temperature.

Water-soluble polymers preferred according to the invention are nonionic. Suitable nonionic polymers are, for example:

Polyvinylpyrrolidones, such as those sold under the name Luviskol ^R (BASF). Polyvinylpyrrolidones are preferred non-ionic polymers in the context of the invention.

Vinyl pyrrolidone / vinyl ester copolymers, such as those sold under the trademark Luviskol ^R (BASF). Luviskol ^R VA 64 and Luviskol ^R VA 73, each vinylpyrrolidone / vinyl acetate copolymers, are particularly preferred nonionic polymers.

Cellulose ethers, such as hydroxypropyl cellulose, hydroxyethyl cellulose and methyl hydroxypropyl cellulose, as are sold, for example, under the trademark Culminal ^ and Benecel ^R (AQUALON).

Suitable amphoteric polymers are, for example, the octylacrylamide / methyl methacrylate / tert available under the names Amphomer ^R and Amphomer ^R LV-71 (DELFT NATIONAL). Butylaminoethyl methacrylate / 2-hydroxypropyl methacrylate copolymers.

Suitable zwitterionic polymers are, for example, the polymers disclosed in German patent applications DE 39 29 973, DE 21 50 557, DE 28 17 369 and DE 37 08 451. Acrylamidopropyltrimethylammonium chloride / acrylic acid or methacrylic acid copolymers and their alkali and ammonium salts are preferred zwitterionic polymers. Other suitable zwitterionic polymers are methacroylethyl betaine / methacrylate Copolymers which are commercially available under the name Amersette (AMERCHOL).

Anionic polymers suitable according to the invention include a .:

Vinyl acetate / crotonic acid copolymers, as are commercially available, for example, under the names Resyn ^R (NATIONAL STARCH), Luviset ^R (BASF) and Gafset ^R (GAF).

Vinyl pyrrolidone / vinyl acrylate copolymers, available, for example, under the trademark Luviflex (BASF). A preferred polymer is the vinyl pyrrolidone / acrylate terpolymers available under the name Luviflex ^R VBM-35 (BASF).

Acrylic acid / ethyl acrylate / N-tert-butyl acrylamide terpolymers, which are sold, for example, under the name Ultrahold ^R strong (BASF).

In cases where the polyurethane contains ionic groups, it has proven to be advantageous if other water-soluble polymers are nonionic or of the same ionicity.

The hair treatment compositions according to the invention contain water-soluble polymers depending on the type of hair treatment composition which is not subject to any restrictions, preferably in amounts of 0.01 to 20% by weight, in particular 0.1 to 10% by weight, based on the total composition.

The polyurethanes and the water-soluble polymers are preferably present in the compositions according to the invention in a ratio of 1:10 to 10: 1. A ratio of 2: 1 to 1: 1 has proven particularly suitable in many cases.

The hair setting agents according to the invention are, in particular, hair setting agents, hair sprays and hair dryer waves. Hair sprays are a particularly preferred embodiment of the hair fixative according to the invention. In another preferred embodiment, the agents according to the invention can also be formulated as a foam aerosol using a propellant.

The preparations according to the invention, which comprise one or more alkoxylated fragrance alcohols, show an optimized fragrance impression due to the content of the alkoxylated fragrance alcohols. Preparations for which the alkoxylated fragrance alcohols produced in the way described in this application are distilled before being added to the preparation and thus freed from the fragrance-producing fragrance alcohol (the alkoxylated fragrance alcohol was almost odorless before the addition) call the alkoxylated fragrance alcohols a fragrance that already characterizes the preparation, which lasts for a long time and thus also survives a longer storage or transport time of the (possibly containing surfactant) preparation. The scent is also well transferred to the object to be treated and adheres reliably there; it is released over a longer period of time and thus reliably leads to the desired fragrance. This can be described as surprising for detergents and cleaning agents as well as for cosmetic preparations.

As already mentioned above, fragrances are added to preparations containing surfactants in particular, in order to improve the overall aesthetic impression of the products and to provide the consumer with a technical, distinctive and unmistakable product in addition to the technical performance (washing, rinsing and cleaning results). In a preferred embodiment of the present invention, in addition to the alkoxylated fragrance alcohols, one or more further components which leave a scent impression can be added to the surfactant-containing preparations. Individual fragrance compounds can be used as perfume oils or fragrances, for example the synthetic products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type. Fragrance compounds of the ester type are, for example, benzyl acetate, phenoxyethyl isobutyrate, pt-butylcyclohexyl acetate, linalyl acetate, dimethylbenzyl carboxylate, phenylethyl acetate, linalyl benzoate, benzyl formate, ethyl methylphenyl glycinate, allyl cyclohexyl hexylateylylyllylpylpropylate, melylalylylpylpropylate, melylalylylpylpropylate, melylalylatepylate, methylatelylylpylate, methylatelylylpylate, methyllalylatepylate, methylalylatepylate, methylateylateylate, methylalylateylate, methylalylateyl, Also worth mentioning here are the esters of fragrance alcohols with inorganic acids or organic acids, as disclosed in the prior art mentioned at the beginning.

The ethers include, for example, benzyl ethyl ether and ambroxan. The aldehydes include e.g. B. linear alkanals with 8 to 18 carbon atoms, citral, citronellal, citronellyloxyacetaldehyde, cyclamenaldehyde, hydroxycitronellal, lileal and bourgeonal.

The ketones include the ionones, α-isomethyl ionone and methyl cedryl ketone. Alcohols include anethole, citronellol, eugenol, geraniol, linalool, phenylethyl alcohol and terpineol. The hydrocarbons mainly include terpenes such as limonene and pinene.

Mixtures of different fragrances are preferably used which are coordinated with one another in such a way that they together produce an appealing fragrance.

Such perfume oils can also contain natural fragrance mixtures, such as are obtainable from plant sources. Natural fragrances include: extracts of flowers (lily, lavender, linden flowers, orange flowers, chamomile, roses, jasmine, neroli, ylang-ylang), stems and leaves (geranium, patchouli, petitgrain, sage, lemon balm, mint, cinnamon leaves), Fruits (anise, coriander, caraway, nutmeg, cloves, juniper), fruit peels (bergamot, lemon, oranges), roots (macis, angelica, celery, cardamom, costus, iris, Calmus, vetiver), woods (pine, sandal, guaiac, cedar, rosewood), herbs and grasses (tarragon, lemongrass, sage, thyme), needles and twigs (spruce, fir, pine, mountain pine), resins and Balsams (galbanum, elemi, benzoin, myrrh, olibanum, opoponax, labdanum). Animal raw materials, such as civet and castoreum, are also suitable.

The fragrance content is usually up to 2% by weight of the total preparation.

The fragrances can be incorporated directly into the wash-active preparations; However, it can also be advantageous to apply the fragrances to carriers which increase the adhesion of the perfume to the laundry and ensure a long-lasting fragrance for the textiles due to a slower fragrance release. Cyclodextrins, for example, have proven themselves as such carrier materials. The cyclodextrin-perfume complexes can also be coated with other auxiliaries.

Surprisingly, however, it was found in the context of the present invention that the fragrance impression of the above-mentioned fragrances additionally added to the (optionally surfactant-containing) preparations can be increased and lengthened if the optionally surfactant-containing preparations contain one or more alkoxylated fragrance alcohols of the general formula (I) with the case in which preparations containing surfactants only contain the aforementioned conventional fragrances. The alkoxylated fragrance alcohols of the general formula (I) are therefore suitable as a fragrance booster, that is to say as a substance which is capable of sustainably intensifying the olfactory impressions of the components of a multi-substance system such as a preparation containing a surfactant or a mixture of two or more fragrances , This phenomenon is also surprising for detergent or cleaning agents as well as for cosmetic preparations. The invention thus also relates to (optionally surfactant-containing) preparations according to the above description, that is to say both washing, rinsing, cleaning or softening agent preparations and also cosmetic preparation with a modified, in particular enhanced and / or extended, content by the content of one or more alkoxylated fragrance alcohols and / or qualitatively changed fragrance impression of the additionally contained fragrance (s).

The present invention further relates to a method for modifying the fragrance impression of one or more fragrance (s) contained in a multi-substance mixture by adding a quantity of one or more alkoxylated fragrance alcohols of the general formula (I) which modifies the fragrance impression

Examples 14 and 15 Improve the Tactile Properties of Hair

Shampoo formulations were produced in accordance with Table 6 below:

Table 6

Strands of hair (2 g) were pre-cleaned with an aqueous surfactant solution and then rinsed thoroughly.

Then 1 g each of the formulations of Examples 14 and 15 per gram of hair were applied to the strands of hair and also thoroughly rinsed out. After the strands of hair had dried under air-conditioned conditions, their tactile properties were examined and assessed by sensors.

The hair treated with the formulation of Example 15 containing the alkoxylated scented alcohol Geraniol + 6 EO was easier to comb and showed advantages in properties such as good smoothness and feel. The sensory profile is shown in the attached FIG. 1. It was determined by the sensory assessment method known to the person skilled in the art. In FIG. 1, “Geraniol 6 EO” is to be understood as the formulation according to Example 15, under “placebo” the formulation according to Example 14.

Example 16 Improvement of Tactile Properties of Hair

Hair rinses (rinse-off) are often used in practice to give the hair special cosmetic properties such as to give an improved grip, better combability, shine or good stylability.

In practice, there are mainly formulations containing non-ionic emulsifiers and thickeners, cationic compounds and care ingredients, e.g. Lipids and the like other cosmetic active ingredients.

A disadvantage of the formulations of the prior art is the generally more or less great strain on the hair due to the conditioning compounds used, which manifests itself in noticeable residues in the hair, a certain amount of sticking and reduced hair volume.

Table 7

In the present example, two rinsing formulations S1 and S2 were used to check whether and which additional effects result from the use of terpene alcohol ethoxylates according to the invention in hair rinses.

0.5 g / g of hair was applied from each of the present formulations S1 and S2. After an exposure time of 20 min, the rinsing was carried out with warm tap water and, after drying, the sensory properties of the strands of hair were checked by a test panel.

The hair treated with formulation S2, like the hair treated with formulation S1, had good combability, soft tips and a pleasant feel. The strands treated with formulation S2 were better assessed with regard to residues in the hair and hair volume.
