USE OF RLILIC ALCOHOL PERFUMES AS REDUCTION AGENTS OF ODOR ODOR FIELD OF THE INVENTION The present invention relates to perfumes of ALOYAL ALCOHOL as reducing agents of the MLLOR. More particularly, it relates to the use of said components to reduce the large amount of smoke coming from the smoke and / or the cooking odors; and / or its precursors to reduce the large amount that comes from perspiration, smoke, and / or kitchen odors.

BACKGROUND OF THE INVENTION Acceptance of Cleaning Products and Laundry for the consumer, is determined not only by the performance achieved by these products, but also by the aesthetics associated with them. Therefore, perfume systems are an important aspect of the successful formulation of such a commercial product. They guarantee the provision of a character of freshness and cleanliness to the cleaned surface or to the washing. In WO 95/04809; A method is described that provides delayed release of an odoriferous alcohol, aldehyde or ketone by hydrolysis of an ester compound. It is guaranteed that said method provides a clean and fresh character to the washed tits. In EP 0,404,470, perfume fragrances are described which reduce the large amount arising from perspiration. US pending application No. 08 / 277,558, describes cleaning and laundry compositions containing a nonionic or anionic ester of a perfume of aLolic acid, to provide perfume release for a longer period than through the use of perfume by itself in the Laundry / Cleaning compositions. THE SOLICITOR HAS NOW FOUND THAT ANOTHER IMPORTANT ASPECT OF THE SUCCESSFUL FORMULATION OF THE COMMERCIAL PRODUCT IS DETERMINED BY THE MAXIMUM RESULTING SURFACE OF THE SURFACE.

Clean and / or La teLa Lavada; SPECIALLY AFTER HIS EXPOSURE TO STRONG HEADS, SUCH AS THE OILS OF PERSPIRATION, THE SMOKE, AND / OR THE KITCHEN. THESE OILS are among the most persistent odors on tits and / or clean and dry surfaces. THE SOLICITOR HAS NOW FOUND THAT THE USE OF ALLOYAL ALCOHOL FRUIT PREDICTERS, WHOSE ALCOHOL IS SELECTED FROM GEAR, NEREL AND MIXED THEM, EXCEEDS THE PROBLEM. Therefore, it is an object of the invention to provide the use of said perfume precursors of aLolic aLcohol to reduce the greater odors that come from perspiration, smoke and / or cooking. Another object of the invention is to provide the use of a perfume of aLiCal alcohol selected from geranium, neroL and mixtures thereof, in order to reduce the selected values of the smoke, cooking, and mixtures thereof.

BRIEF DESCRIPTION OF THE INVENTION The present invention relates to the use of perfume precursors of aLicoL alcohol, whose perfume of aLicoL alcohol is selected from geranium, neroL and mixtures thereof, in order to reduce the selected values of the perspiration, smoke and cooking temperature. , and mix them. Preferably, said precursors are nonionic or anionic esters of said perfumes of aLolic aLcohol. The present invention also relates to the use of a perfume of aLiCoL aLiCiOl selected from geranium, neroL and mixtures thereof, in order to reduce the selected oLLes of the smoke, cooking and mixture oLLs. In another preferred embodiment of the invention, the aforementioned precursor / perfume is incorporated into a cleaning or laundry composition.

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to the use of a perfume precursor of aLicoL aLcohol, whose perfume of aLicoL aLcoL is selected from geranium, neroL and mixtures thereof, to reduce the selected oLLes oF the perspiration, smoke, cooking odors , and mix them, preferably smoke such as cigarette smoke and fire smoke, on clean and dry surfaces and / or tits, washed and dried, which are then exposed to these types of smoke. The present invention is also directed to the use of aLiCoL aLcohol perfumes to reduce the selected loWs oF smoke oLores, cooking, and mix them. Perfume of aLiCal alcohol An essence component for the purpose of the invention, is a perfume of aLiCal alcohol selected from geranium, neroL and mixtures thereof. Geranium and neroL are trans / cis structural isomers (in position 2.3 of the double layer) of the molecules that have the form: H0-CH5a-CH = C (CH3 >); -CH? A-CH1 «! - CH = C (CH3) a. Another essential component of the invention is the precursor of said perfume of aLolic aLcohol. The precursor is preferably a non-ionic or anionic ester of said perfume of aLolic aLcohol. Non-unique ester of perfume from the perfume of aLolIcAl alcohol. The non-ionic or anionic ester of said aLic acid perfume for use in the present is an ester of formula: 0 R - [C-0-CHa-CH - == C (CHa> -CHaCHaCH = - - = C (CHa,) a!] R, in which n is an integer of 1 or greater, and in which the R is selected from an alLquiLo, aLqueniLo, aLquiniLo, alLquiLariLo or ariLo group, nonionic or anionic, substituted or unsubstituted, straight chain, branched or cyclic, of d.-CaO, and represents the group attached to the carboxylic acid carboxylic acid function used to make the perfume ester.The product or products, and the hydrolysis rate of the ester. can be controlled by the selection of R. More specifically, although it is not limited by theory, it is believed that when R is an electron donor group (such as nickel), the hydrolysis product will tend to be the redistributed aLcoholic aLcohol. , whereas the electron-attracting groups (such as phenol) will tend to liberate the perfume alcohol not redistributed by hydrolysis. Also included are acid esters that have more than one acid entity per molecule (eg, diesters, triesters) within the alcoholic acid esters. Preferably, R is selected from an alkylic group of C2-C2 or C3-C2, C3-C2, C3-C2, C3-C2, C3-C2, C3-C3, C3-C2, C3-C2, C3-C2, C3-C2, C3-C2 or cyclicals. As mentioned above, the R entity may be unsubstituted or substituted with one or more nonionic and / or anionic substituents. These substituents may include, for example, halogens, nitro, carboxyl, carbonyl, suLp, suLphonate, hydroxy, and alkoxy, and mixtures thereof. Preferred esters for use in the present are: referred to herein as "digeranyl succinate" and referred to herein as "geraniLo phenylacetate" and referred to in the present as "Laurato de geraniLo", as well as neriLo esters corresponding to these geraniLo esters, including the mixed ester of geraniLo succinate and neriLo, and especially mixtures of the corresponding geraniLo and neriLo esters. Preferred esters for use in the present are selected from digeranyl succinate, dinerol succinate, geranium succinate and nerium, and mixtures thereof. Also provided herein is the use in accordance with the invention of said esters in products of Cleaning or Laundry, which are typically used to wash tits and clean hard surfaces such as vase and other surfaces in need of cleaning and / or disinfection. Laundry compositions that elicit the contact of the ester perfume of aLicoL aLicoL with Theta are preferred, as described above. It is understood that this includes, not only detergent compositions that provide benefits of cleansing, but also laundry compositions such as blender softening compositions added in the rinse, and aggregate dryers compositions (eg, foils) that provide benefits of softness and / or antistatic. The allylic perfume ester or esters typically comprise from about 0.01% to about 10%, preferably from about 0.05% to about 5%, and from about 0.1% to about 2% by weight of the composition is most preferred. The optional ingredients to formulate such laundry and cleaning compositions include one or more of the following. Tissue softening agents. The blister softening agents suitable for use herein are selected from cationic, nonionic, and mixed blended teat softening agents. The preferred fabric softening agents for use in the present compositions are quaternary ammonium compounds or amine precursors having the following formula (I) or (II): (I) (II) Q is selected from -0-C (0) -, -C (0) -0-, -0-C (0) -0-, NR ^ -CÍO) -, -C < 0) -NR; R * is < CHA! > P1-Q-T »or T3; Ra is (CHa!) M-Q-Tv * or Ts OR R3 Ra is aCLOSuite of C ..- C- * or hydroxysLL of C.t.-Ct + or H; Rw is H or aLQUER of d.-C. + or hydroxylLquiLo of d-Ci *; T1, T '? , T: a, T, TB are (The same or different) aLquiLo or aLqueniLo of Cn-Ca-a .; n and m are integers from 1 to 4; and X ~ is a compatible anion with the softener, such as chloride, methylsulphate, etc. The chain T *, T58, T3, T1 *, Tß of aLquiLo or aLqueniLo, must contain at least 11 carbon atoms, preferably at least 16 carbon atoms. The chain can be straight or branched. Sebum is a convenient and inexpensive source of long-chain material and long-chain products. Particularly preferred are the compounds in which Tx, T '?, Ta, T' *, TB represent the mixture of long chain materials typical of tallow. Specific examples of quaternary ammonium compounds suitable for use in the present invention are the following: 1) N, N-di (seboyl-L-oxyethyl) -N, N-dimethyl-ammonium chloride; 2) N, N-di (seboiLoxietiL) -N-methyl-N- (2-hydroxyethyl) ammonium chloride; 3) N, N-di (2-seboiLoxi-2-oxoetiL) -N, N-dimethylammonium chloride; 4) N, N-di (2-seboiLoxietiLcarboniL-oxietiL) -N, N-dimetiLamonium chloride, 5) N- (seboiLoxi-2-etiL) -N- (2-seboiLoxi-2-oxo-etiD-N, N-dimethylammonium; 6) N, N, N, -tri (seboiLoxietiL) -N-methyl-ammonium chloride; 7) N- (2-seboxy-Oxo-2-oxoetiL> -N- (seboyl) -N jN-Dimeti-Lamonium chloride; 8) 1,2-Disodioxy-3-trimethyl-propane-L-propane; and mix of any of the previous materials. Of these, Compounds 1-7 are examples of compounds of Formula (I); Compound 8 is a compound of Formula (II). Particular preference is given to N, N-di (2-seboiLoxi-etiL) -N, N-dimetiLamonium, where Sebum chains are at least partially unsaturated. The level of unsaturation of the tallow chain can be measured by means of the iodine value (IY) of the corresponding fatty acid, which in this case should preferably be in the range of 5 to 100, distinguishing two categories of compounds, those having a IY below 25, and Those who have it above 25. In reality, for the Formula (I) compounds made from tallow fatty acids having an IY of 5 to 25, preferably 15 to 20, has been found that a weight ratio of the cis / trans isomer greater than about 30/70, preferably greater than about 50/50 and preferably greater than about 70/30, provides optimum concentration ability. For Formula (I) compounds made from tallow fatty acids having an IY above 25, it has been found that the ratio of cis to trans isomers is less critical, unless very high concentrations are required. Other examples of quaternary ammoniums of Formula (I) and (II) are obtained, for example: - replacing the "sebum" in the above compounds with, for example, coco, pamma, LauriL, oLeiL, ricinoLeiL, steariL, paLmitiLo, or Similar; said acyl chains are either fully saturated or preferably at least partially unsaturated; REPLACING THE "METHOD" IN THE PREVIOUS COMPOUNDS WITH ETHYL, ETOXY, PROPYLO, PROPOXY, ISOPROTIL, BUTYLO, ISOLUTYL OR T-BUTYL; - Replacing the "chloride" in the above compounds with bromide, methylsulphate, formate, sulate, nitrate, and simiLares. In fact, the anion is present only as a counter ion of positively charged quaternary ammonium compounds. The nature of the contraction is not in abso- lute criticism for the practice of the present invention. The scope of this invention is not considered to be limited to any particular anion. By "amine precursors of the same" means The secondary or tertiary amines corresponding to the quaternary ammonium compounds, said amines are substantially protonated in the compositions present due to the claimed pH values. The quaternary ammonium compounds or amine precursors of the present are at levels of 1% to 80% of the compositions present, depending on the embodiment of the composition which may be digested with a preferred level of active agent of 5% to 15%. %, or concentrate, with a preferred level of active agent from 15% to 50%, preferably 15% at % For the preceding tea-softening agents, the pH of the compositions present is an essential parameter.

In fact, it influences the stability of quaternary ammonium compounds or amine precursors, especially under conditions of prolonged storage. The pH, as defined in the present context, is measured in pure compositions at 20 ° C. For optimum hydrolytic stability of these compositions, the pH in pure form, measured under the conditions mentioned above, should be in the range of 2.0 to 4.5, preferably 2.0 to 3.5. The pH of these compositions can be regulated by the addition of a Bronsted acid.

Examples of suitable acids include inorganic mineral acids, carboxylic acids, in particular low molecular weight carboxylic acids (C __-C3), and alkylsulfonic acids. Suitable inorganic acids include HCL, HaSOf, HN03 and H3P0f. Suitable organic acids include formic, acetic, citric, methylsulphonic and ethyl sulphonic acids. Preferred acids are citric, hydrochloric, phosphoric, formic, ethylsulphonic, and benzoic acids. The useful softening agents are also non-ionic tonic softening materials, preferably in combination with cationic softening agents. Typically, said nonionic fabric softener materials have an HLB of 2 to 9, typically 3 to 7. Such nonionic fabric softening materials tend to disperse easily, either on their own or when combined with other materials, such as a Long single chain alkyl cationic surfactant described in detail below. The dispersion capacity can be improved by using more Long single chain cationic alkyl surfactant, mixing with other materials as indicated below, use of warmer water, and / or further stirring. In general, the selected materials should be relatively crystalline, high melting point, (e.g.,> 40 ° C) and relatively insoluble in water. The optional non-ionic softener level in the present compositions typically is from about 0.1% to about 10%, preferably about 1% to about 5%. Preferred nonionic softeners are partial fatty acid esters of polyhydric alcohols, or anhydrides thereof, in which the alcohol, or anhydride, contains from 2 to 18, preferably from 2 to 8 carbon atoms, and each portion of fatty acid contains from 12 to 30, preferably from 16 to 20 carbon atoms. Typically, these softeners contain from 1 to 3, preferably 2 fatty acid groups per molecule. The polyhydric alcohol moiety of the ester can be ethylene glycol, glycerol, poly (eg, di-, tri-, tetra-, penta-, and / or hexa-) glycerol, xylitol, sucrose, erythritol, pentaerythritol, sorbitol or sorbitan. . Particularly preferred are sorbitan esters and poLigLiceroL monostearate. The fatty acid portion of the ester is usually derived from fatty acids having from 12 to 30, preferably from 16 to 20, carbon atoms; Typical examples of said fatty acids are tauric acid, myristic acid, palmitic acid, stearic acid, oleic and behenic acid. The highly preferred optional nonionic softening agents for use in the present are the sorbitan esters, which are esterified dehydration products of sorbitol, and the glycerol esters.

Commercial sorbitan monostearate is a suitable material. Also useful are mixtures of sorbitan stearate and sorbitan palmitate having weight ratios of stearate / palmitate ranging from about 10: 1 to about 1:10, and 1,5-sorbitan esters. Preferred in the present are glycerol and polyglycerol esters, especially mono- and / or di-esters of glycerol, diglycerol, triglycerol, and polyglycerol (eg, polyglycerol monostearate) under a trade name of Radiasurf 7248). Useful glycerol and polyglycerol esters include monoesters with stearic, oleic, palmitic, tauric, isostearic, myristic, and / or behenic acids, and diesters of stearic, oleic, palmitic, tauric, isostearic, behenic, and / or myristic acid. It is understood that the typical monoester contains some di- and tri-ester, etc. The "glyceryl esters" also include the polyglycerol esters, for example diglycerol to octaglycerol. The polyglycerol polyols are formed by condensation of glycerin or epichlorohydrin together to bind the glycerol entities by ether linkages. The mono- and / or di-esters of the polyglycerol polyols are preferred, the fatty acyl groups typically being those described hereinabove for the sorbitan and glycerol esters. Additional fabric softening agents useful in the present are described in U.S. 4,661,269; 4,439,335; U.S. 3,862,870; 4,308,151; 3,886,075; 4, 233, 64; 4, 401, 578; 3,974,076; 4,237,016; and EP 472,178. Fully formulated fabric softening compositions preferably contain, in addition to the components described above, one or more of the following ingredients. Concentrated compositions may require organic and / or inorganic concentrating aids, to reach even higher concentrations and / or to satisfy a higher standard of stability, depending on the other ingredients. The surfactant concentration aids are typically selected from the group consisting of long single chain cationic alkyl surfactants; nonionic surfactants; amine oxides; fatty acids; or mixtures thereof, typically used at a level of 0 to about 15% of the composition. Inorganic viscosity control agents that can also act in a similar manner or increase the effect of the surfactant concentration aids, include water soluble ionizable salts which can also be optionally incorporated in the compositions herein. A large variety of ionizing salts can be used. Examples of suitable salts are the halides of the metals of group IR and IIR of the Periodic Table of the Elements, for example, calcium chloride, magnesium chloride, sodium chloride, potassium bromide, and lithium chloride. Ionizable salts are particularly useful during the process of mixing the ingredients to make the compositions present, and then to obtain the desired viscosity. The amount of ionizable salts used depends on the amount of active ingredients used in the compositions, and can be adjusted according to the conveniences of the formulator. Typical levels of salts used to control the viscosity of the composition are from about 20 to about 20,000 parts per million (ppm), preferably about 20 to about 11,000 ppm, by weight of the composition. Alkylene polyammonium salts may be incorporated into the composition to provide viscosity control in addition to, or in place of, the above water-soluble ionizable salts. In addition, these agents can act as scavengers, forming ion pairs with the anionic detergent carried in the main wash, in the rinse, and on the tits, and can improve the performance of softness. These agents can stabilize the viscosity on a wider scale of temperature, especially at low temperatures, compared to inorganic electrolytes. Specific examples of alkylene polyammonium salts include l-lysine monohydrochloride and 1,5-diammonium-2-methylpentane dihydrochloride. Another optional, but preferred, ingredient is a Liquid vehicle. The liquid vehicle used in the present compositions is preferably the least water mainly, due to its low cost, relative availability, safety and compatibility with the environment. The water level in the liquid vehicle is preferably at least about 50%, preferably at least about 60% by weight of the vehicle. Mixtures of water and organic solvents of low molecular weight, for example, less than about 200, for example, lower alcohols such as ethanol, propanol, isopropanol or butanol, are useful as the liquid carrier. Low molecular weight alcohols include dihydric (glycol, etc.), trihydric (glycerol, etc.), and higher polyhydric alcohols (polyols). Other optional ingredients are soil-removing polymers, bactericides, colorants, perfumes, preservatives, optical brighteners, anti-ionization agents, anti-foaming agents, and the like. Fully formulated cleaning or laundry compositions, such as detergent compositions, preferably contain, in addition to the components described above, one or more of the following ingredients selected from: builders, bleaching agents with or without bleach activators, enzymes, enzyme stabilizers, detersive surfactants, chelating agents and mixtures thereof. An exemplary description of said components can be found in IO 94/03572 and WO 94/03552. Other preferred optional ingredients include polymeric soil release agents, materials effective to inhibit the transfer of dyes from one teat to another during the cleaning process (i.e., dye transfer inhibiting agents), polymeric dispersing agents, suds suppressors, brighteners. optical or other brightening agents or bleaching agents, quetatadores agents, fabric softening clay, anti-static agents, other active ingredients, vehicles, hydrotropes, processing aids, dyes or pigments, solvents for liquid formulations, solid fillers for bar compositions, etc. The liquid detergent compositions may contain water and other solvents as carrier. Suitable are low molecular weight alcohols, primary or secondary, exemplified by methanol, ethanol, propanol and isopropanol. Monohydric alcohols are preferred for solubilizing the surfactant, but polyols such as those containing from 2 to about 6 carbon atoms, and from 2 to about 8 hydroxy groups (for example, 1,3-propanediol, ethylene glycol, glycerin and 1,2-propanediol). The compositions may contain from 5% to 90%, typically from 10% to 50%, of said vehicles. Granular detergents can be prepared, for example, by spray drying (density of the final product approximately 520 g / L) or agglomeration (density of the final product above approximately 600 g / t) of the base granule. The rest of the dry ingredients can then be mixed in granular or powder form with the base granule, for example, in a rotating mixing drum, and the liquid ingredients can be applied by spraying (for example, non-ionic surfactant and perfume) . The detergent compositions herein will preferably be formulated so that during use in aqueous cleaning operations, the Wash water has a pH of between about 6.5 and about 11, preferably between about 7.5 and 10.5. The laundry products are typically at a pH of 9 to 11. The techniques for controlling the pH at the recommended use levels include the use of pH regulators., alkalis, acids, etc., and are well known to the person skilled in the art. The invention will be illustrated in the following non-limiting example, in which all percentages are based on weight, unless otherwise indicated.

EXAMPLE Washing Procedure Two groups of fabrics (ie, knitted cotton shirts) were treated with a liquid fabric softener composition in cold water. The first group was treated with a fabric softening composition fl, while the second group was treated with a nipple softening composition B. The washing procedure employing Composition A constitutes one embodiment of the invention, while the Washing procedure which The composition B is from the prior art. The formulation is defined below: (1) Di- (Seboyl (soft) -oxiethyl) dimethylammonium chloride (2) Silicone DC-110R, sold by Dow-Corning (3) Rzul bright polar (4) Ester 3,7-dimethyl-2,6-octadienyl of 1,4-butanedioic acid.

Exposure procedure to the smoke odor The washed and dried fabrics were then suspended for 1 minute in a 200 liter drum that had previously been saturated with cigarette smoke. The saturation of the drum was obtained with the cigarette smoke by placing a smoking cigarette in the closed drum for 2 minutes. Then, the cigarette was removed to be replaced by the two groups of fabrics. After exposure of the fabrics to the cigarette smoke, the groups were removed from the drum and suspended in the open air for 45 seconds, wrapped in aluminum foil for 24 hours and subsequently subjected to sensory analysis. Sensory analysis After exposure to smoke, the perceived intensity of the residual odor on the teat was evaluated by a panel of 6 expert judges, trained for sensory evaluations. In this case, an expert is defined as a person who has at least 6 months in training and with proven evidence of olfactory sensitivity. The data obtained using the intensity scale of perfumes was averaged to give a consensus value for the perceived intensity of the residual odor. The perfume intensity scale is as follows: 0 - no odor, 25 - light odor, 50 - moderate odor, 75 - very strong odor, and 100 - extremely strong odor RESULTS It is noted that the use of geraniol released by hydrolysis of digeranyl succinate (3,7-dimethyl-2,6-octadienyl 1,4-butanoic acid ester) in a liquid fabric softening composition, provides an improved reduction of the smell that arises from the smoke on the clean and dry cloth. Identical results were obtained when the cloth was exposed to cooking odor in accordance with the following test: After undergoing the washing procedure mentioned above, the fabrics (ie, knitted cotton shirts) washed and dried, were exposed to odors of kitchen in accordance with the following procedure: Kitchen staff involved in the cooking operation used four groups of fabrics for 4 hours.

Afterwards, the groups were suspended outdoors for 45 seconds, wrapped in aluminum foil during 24 hours, and subsequently underwent the sensory analysis mentioned above. Similar results were obtained when cotton garments were exposed to perspiration. After having been subjected to the washing procedure mentioned above, the washed and dried garments were cut into two equal halves so that one half treated with the product A could be placed together with the complementary half treated with product B. Afterwards, this "divided article" was used by a panel of 20 people during 8 hours of normal activity (without effort) or 1 to 2 hours of sports session (with effort). Then, the divided items were evaluated on both halves according to the sensory analysis mentioned above. Similar results were obtained when sheets were treated, also cut into two equal halves, respectively with product A and product B, which were used by a panel of 20 users, based on a 5-night exposure.
