Abstract

The invention discloses the use of diols as biocides, said diols having one cycloaliphatic group.

Description

Use of cycloaliphatic diols as biocides The invention relates to the use of diols with a cycloaliphatic group (also referred to below as diols for short) as a biocide.

Biocidal agents kill microorganisms such as bacteria, fungi, yeasts, algae or viruses or at least prevent their reproduction and / or growth.

With a wide variety of substrates there is the desire or often the need for biocidal equipment. It is e.g. for substrates for medical applications, sanitary or sanitary applications, in the food sector, especially in food packaging, or substrates for a variety of industrial applications, in particular filters, e.g. for air conditioners.

Biocides are also used as preservatives. Of particular importance here is the use as a preservative for liquid preparations which are used for medical, hygienic, cosmetic or dermatological purposes.

Biocidal effects were found with different chemical compounds. In connection with alcohols, it is known that 1, 2-alkanediols have a good biocidal activity, as also by Gerhard Schmaus, Antje Pfeiffer, Sabine Lange and Aurelie Trunet in Cosmetics & Toiletries, VoI 123, No 10, October 2008, page 53 bis 64 will be described.

For the manifold uses of biocidal active ingredients, alternative solutions are constantly being sought.

Object of the present invention were therefore biocidal agents that have a good biocidal activity against as many microorganisms, are easy to handle and can be used in many ways. Accordingly, the use defined above was found.

The diol used in the invention is a diol having a cycloaliphatic group. The cycloaliphatic group preferably consists of 5 to 10 C atoms. It may be a monocyclic or bicyclic group. Most preferably it is a bicyclo [2.2.1] heptane group; Bicyclo [2.2.1] heptane is also called Norbornan.

The two hydroxyl groups of the diol may be bonded to the cycloaliphatic group directly or as a hydroxyalkyl group, preferably as a C1 to C5 hydroxyalkyl group. In a particularly preferred embodiment, it is a hydroxymethyl group, hydroxyethyl group, hydroxy-n-propyl group, hydroxy isopropyl group. The diols, apart from the two hydroxyl groups, preferably have no further functional groups. The cycloaliphatic group may be substituted by further aliphatic groups, especially alkyl groups, more preferably C1 to C4 alkyl groups. Suitable diols preferably have a molecular weight of at most 250 g / mol, in particular 200 g / mol.

Particularly suitable diols are substituted by two hydroxyalkyl groups, in particular C 1 -C 3 hydroxyalkyl groups, substituted bicyclo [2.2.1] heptanes (norbornanes).

Hereinafter, suitable diols are named:

A) 3- (4-hydroxymethylcyclohexyl) -propan-1-ol (CAS: 109942-23-6)

From 20 to 25% by weight of 2- (3-hydroxymethylcyclohexyl) propan-1-ol, the sum being 100% by weight.

The CHA diols are preferably used as a mixture, in particular with the above-mentioned compositions.

The ENB diols are formed in particular as a mixture in the hydroformylation of 5-ethylidene-norbornene (also 5-vinyl-bicyclo [2.2.1] hept-2-ene, CAS: 3048-64-4) and subsequent hydrogenation. 5-Etyliden-norbornene example, manufactured by the company. Ineos.

The ENB diols are preferably used as a mixture.

The synthesis of 2,3-dimethylol norbornane is carried out by the Diels-Alder reaction of di-cyclopentadiene and fumaric acid diester or fumaric acid. Preferably, dicyclopentadiene is reacted with fumaric acid diester, in particular dimethyl fumarate. The reaction takes place in a manner known to the person skilled in the art. The reaction product of dicyclopentadiene and fumaric acid provides 5-norbornene-2-endo, 3-exo-dicarboxylic acid (CAS: 1200-88-0), which can be obtained, for example, from Aldrich. By means of subsequent hydrogenation, the reaction products of dicyclopentadiene and fumaric acid or fumaric acid can be converted to 2,3-dimethylol norbornane.

The synthesis of 2,5- and / or 2,6-dimethylol norbornane is carried out by the skilled person from the Diels-Alder reaction of dicyclopentadiene and acrolein or acrylic acid or acrylic acid esters, especially methyl and -etylester. The reaction of dicyclopentadiene and acrylic acid gives 5-norbornene-2-carboxylic acid (CAS: 120-74-1).

Preferably, dicyclopentadiene is reacted with acrolein to give 5-norbornene-2-carbaldehyde (CAS: 5453-80-5). Norbornene-2-carboxylic acid and norbornene-2-carbaldehyde can be obtained, for example, from Aldrich. The reaction products of dicyclopentadiene and acrolein or acrylic acid or acrylic acid esters, in particular methyl and -etylester are then subjected to a hydroformylation with subsequent hydrogenation. In the synthesis, an isomeric mixed from 2,5- and 2,6-dimethylol norbornane. Preferably, the mixture is not separated, but used in this form as 2,5-, 2,6-Dimethylolnorbornan.

Esterase inhibitors may also be added to the preparations mentioned, as further deodorant. Such inhibitors are especially trialkyl citrates, such as trimethyl citrate, tripropyl citrate, triisopropyl citrate, tributyl citrate and especially triethyl citrate (Hydagen CAT, Henkel). They inhibit enzyme activity and thereby reduce the formation of body odors. Furthermore, as esterase inhibitors and sterol sulfates or phosphates, such as lanosterol, cholesterol, dicarboxylic acids and their esters. In some preparations, such ingredients may enhance or qualitatively alter the antimicrobial activity of the diols described herein.

The diols can be used alone or in mixtures for the treatment of acne. It can e.g. Combinations of the diols described herein with other substances such as phenoxyethanol, phenoxypropanol, benzalkonium chloride, cetrimonium bromide, benzethonium chloride or salicylic acid may be used. If the mixture is applied to a skin area affected by acne, the mixture will have an anti-acne effect.

A wide variety of anionic surfactants may be useful in presentations of this invention. Non-limiting examples of anionic surfactants can be selected from the group of alkyl and alkyl ether sulfates or from the group consisting of sulfonated monoglycerides, sulfonated olefins, alkylaryl sulfonates, primary or secondary alkanesulfonates, alkyl sulfosuccinates, acyl taurates, acyl isethionates, alkyl glyceryl ether sulfonates, sulfonated methyl esters, sulfonated fatty acids, alkyl phosphates, acyl glutamates, acyl sacosinates, alkyl sulfoacetates, acylated peptides, alkyl ether carboxylates, acyl lactylates, anionic fluorinated surfactants, and mixtures thereof. Anionic surfactants can be used effectively for some representations of this invention. The present invention includes personal care and household applications consisting of one or more nonionic surfactants. Some nonionic surfactants are condensation products of ethylene oxide with very different components that have reactive hydrogen atoms and long hydrophobic chains (C12-C20). Such products (ethoxamers) contain long hydrophilic polyoxyethylene subunits, such as condensation products of poly (ethylene oxide) with fatty acids, fatty alcohols, fatty amides, polyhydric alcohols and polypropylene oxide. Polyoxamers include, for example, block copolymers of polyoxyethylenes and polyoxypropylene having an average molecular weight of 3,000 to 5,000 and a preferred average molecular weight of 3,500 to 4,000. They contain about 10 -80% hydrophilic polyoxyethylene groups based on the weight of the block copolymer (eg, Pluronic F127 ). Other non-ionic surfactants are, for example, alkyl polyglucosides, alkanolamides, ethers of fatty acids with ethylene oxide or propylene oxide, aminosides, eg cocamidopropylamine oxide.

The invention also includes personal care and household product formulations containing one or more amphoteric surfactants. Nonlimiting examples of amphoteric surfactants are: secondary or tertiary aliphatic amine derivatives in which the aliphatic chain, linear or branched, has at least 8 to 22 C atoms and an anionic group such as carboxylates, sulfonates, sulfates, phosphates or phosphonates, acyl / Dialkylethylenediamines, acylamphoacetates, disodium acylamphodipropionates, sodium acylamphohydroxypropylsulfonates, disodium acylamphoacetates, sodium acylamphopropionates in which the acyl group represents either an alkyl or an alkenyl group, N-alkylamino acids or imino acids, such as aminopropylalkylglutamide, alkylaminopropionic acid, sodium alkyliminopropionate, alkylglycinate and carboxyglycinates or Sodium cocoglycinates, Cs-Cis-betains, Cs-ds-sulfobetains, C8-C24-alkylamido-C 1 -C 4 -alkylenbetaines, imidazolinecarboxylates, alkylamphocarboxycarboxylic acids, alkylamphocarboxylic acids (eg, lauroamphoglycinate) and N-alkyl-β-aminopropionate or iminodipropionate ,

The invention includes personal care and household product formulations consisting of a combination of anionic, nonionic and amphoteric surfactants.

The diols may also be formulated together with "mildness-enhancing" agents in personal care or household products. cationic and nonionic polymers, co-surfactants, moisturizing substances or mixtures thereof.

In the formulations described stabilizers are also incorporated in most cases in order to lead to improved stress and storage stability. In some It is preferred to use representations of stabilizers comprising hydroxyl groups, for example 12-hydroxystearic acid, 9,10-dihydroxystearic acid, tri-9,10-dihydroxystearin and tri-12-hydroxystearin (hydrogenated castor oil consists for the most part of tri-12-hydroxystearin).

In some presentations, the stabilizers that are added to the antimicrobial preparations consist of polymeric thickeners. A thickener is a substance that can increase the viscosity of a liquid preparation. Thickeners can be divided into two groups: those that have the best effect in water-based formulations and those that have the best effect in oil-based formulations.

Thickeners can also be divided according to their origin, e.g. synthetic polymers, natural polymers and their derivatives, mineral polymers or according to their ionic character (anionic, cationic, nonionic or amphoteric thickeners).

Another class of stabilizers that may be included in some antimicrobial formulations of the present invention include dispersed amorphous silica: e.g. evaporated silica, precipitated silica and mixtures thereof. The term

"Dispersed amorphous silica" refers to finely divided, non-crystalline silica having an average particle size of silica agglomerates of less than 100 microns.

In some representations, where amorphous silica is used as the stabilizer, it is added in the range of 0.1 to 10%, preferably in the range of 0.25-8%, and more preferably in the range of 0.5-5%.

Another class of stabilizers used in the antimicrobial formulations of the present invention are the dispersed smectide clay from the group of bentonites and hectorites and mixtures thereof. Bentonite is a colloidal aluminum sulphate-containing clay. Hectorite is a clay consisting of sodium, magnesium, lithium, silicon, oxygen, hydrogen and fluorine. When disperse clay-containing soils are used in detergents, they are usually incorporated in the formulation from 0.1 to 10%, preferably from 0.25 to 8%, and more preferably from 0.5 to 5%.

In the representations of the present invention it is also possible to use passivation agents for stabilization, for example hectorite, bentonite, montmorollonite, nontronite, saponite, sauconite, beidellite, allevardite, illite, halloysite, attapulgite, sepiolite and / or talcum. These substances are often used in Deoprodukten, aerosols or sticks to keep contained antiperspirants in solution. Other stabilizers, such as fatty acids or fatty alcohols, may also be used in some of the formulations mentioned herein.

In addition, further ingredients may also be included in the diols in antimicrobial preparations. These ingredients can i.a. are assigned to the following functional classes: abrasives, anti-acne agents, anticaking agents, antioxidants, binders, biological additives, bulking agents, complexing agents, chemical additives, dyes, cosmetic astringents, cosmetic biocides, denaturants, emulsifiers, emollients, film formers, perfumes , Moisturizers, opaque pigments, preservatives, propellants, reducing agents, skin bleaching agents, skin-repelling agents, skin protection agents, anti-wrinkle agents, adjuvants, solvents, foam boosters, hydrotropic agents, solubilizers, dispersants, gelling agents, sun protection agents, UV light filters, viscosity enhancers or reducers, antibiofilm agents, antiplaque agents, antiginitis agents, antiperiodontitis agents, flavoring agents, sweeteners, fluorinating agents, enzymes, peptides.

For the use of the diols as preservatives in liquid preparations in particular preparations of importance, the water as a solvent, either as the sole solvent or in admixture with other solvents.

The liquid preparations may be low-viscosity to high-viscosity preparations.

The content of the 1,3-diols in the preparations should preferably be at least 0.001, particularly preferably at least 0.01 and very particularly preferably at least 0.05 part by weight of 1,3-diol per 100 parts by weight of the preparation. For the intended effect, it is generally meaningless to use more than 2 parts by weight or more than 1 part by weight of 1,3-diol per 100 parts by weight of the preparation.

When using the 1, 3-diols as biocide, be it in the above preparations or for the biocidal finishing of moldings, a single, defined 1, 3-diol or a mixture of 1, 3-diols can be used. In particular, 1, 3 diols can always be used in combination with other biocides and thus support the action of other biocides.

The 1, 3-diols as biocides have excellent activity against microorganisms, such as viruses, yeasts, fungi, algae and especially against bacteria, are gram-negative or gram-positive bacteria. They are therefore suitable for biocidal finishing of moldings and for the preservation of liquid preparations, sprays, foams or Gels to protect against attack and growth of various microorganisms.

The moldings equipped with the diol are in particular moldings for medical applications, for sanitary and hygiene applications, for packaging or storage of food or for industrial purposes, eg. B. filters in air conditioners.

The diols are also suitable as preservatives in liquid preparations, in gaseous preparations, sprays, foams or gels.

In particular, aqueous preparations containing organic compounds are often a good breeding ground for microorganisms and should be preserved by the addition of biocides.

The liquid preparations generally contain at least one solvent and at least one further chemical compound, be it an organic compound, e.g. also a polymer, or an inorganic compound. Generally, such formulations contain a variety of other different compounds that are desired or required for the particular application of the formulation.

The solvents used are water or organic solvents or mixtures of water and organic solvents, eg. As alcohols, into consideration; in the latter case they may be homogeneous mixtures or emulsions of water in organic solvents or vice versa (water in oil or oil in water emulsions). In the solvent, the other constituents of the preparation are dissolved, emulsified or dispersed.

The liquid preparations may be, for example, polymer dispersions or polymer solutions which optionally contain further additives, for example pigments, dyes, stabilizers, thickeners, leveling agents, emulsifiers and coemulsifiers, surfactants, oils, other preservatives, perfume oils, cosmetic care products. and active substances such as AHA acids, fruit acids, ceramides, phytantriol, collagen, vitamins and provitamins, for example vitamins A, E and C, retinol, bisabolol, panthenol, natural and synthetic light stabilizers, natural substances, opacifiers, solubilizers, repellents, bleaching agents, colorants, Tanning agents, tanning agents (eg dihydroxyacetone), micropigments such as titanium oxide or zinc oxide, superfatting agents, pearlescent waxes, solubilizers, complexing agents, fats, waxes, silicone compounds, hydrotropes, dyes, pH regulators, reflectors, proteins and protein hydrolysates, salts, gelling agents, others Bodying agent, silicones, Feuchth altemers, moisturizers, UV sunscreens, antioxidants, defoamers, antistatic agents, emollients, plasticizers, peroxides, etc. For the use of the diols as preservatives in liquid preparations in particular preparations of importance, the water as a solvent, either as the sole solvent or in admixture with other solvents.

The liquid preparations may be low-viscosity to high-viscosity preparations.

High-viscosity preparations are in particular also ointments and creams.

Examples

Preparation of the diols

1. ENB-diol:

1350 g of a mixture of 5-ethylidene-2-norbornene and toluene (VoI 1: 1) were placed together with 34 mg of Rh (CO) 2 (acac) in a 2.5 liter stirred autoclave. The autoclave was first adjusted to 20 bar with oxo gas (CO / H2, 1: 1). Subsequently, the mixture was heated to 140 ⁰ C and the pressure increased by means of oxo gas to 600 bar. The reaction mixture was cooled after 12 h and relaxed. The reaction effluent contained about 90% of corresponding dialdehydes. The isomeric mixture of dialdehydes was distilled and then hydrogenated in isopropanol with Raney nickel at 170 ⁰ C and 280 bar quantitatively to ENB-diol.

2. 2,3-Dimethylolnorbornane (2,3-DMNB)

245 g of 5-norbornene-2-endo, 3-exo-dicarboxylic acid was hydrogenated in isopropanol with Raney nickel at 150 ° C and 280 ⁰ C to 2,3-Dimethylolnorbornan. The crude 2,3-DMNB was subsequently worked up by distillation (yield: 73%).

3. 2,5-, 2,6-dimethylolnorbornane (2,5-, 2,6-DMNB)

500 g of a mixture of 5-norbornene-2-carbaldehyde and toluene (VoI 1: 1) were placed together with 20 mg of Rh (CO) 2 (acac) in a 1 liter stirred autoclave. The autoclave was first adjusted to 20 bar with oxo gas (CO / H2, 1: 1). Subsequently, the mixture was heated to 120 ⁰ C and the pressure increased by means of oxo gas to 600 bar. The reaction mixture was cooled after 14 hours and relaxed. The reaction effluent contained about 75% of desired aldehydes. The crude isomeric mixture of 2,5- and 2,6-norbornane dicarboxylates was distilled and then reacted quantitatively in isopropanol with Raney nickel at 170 ° C. and 280 bar to give the 2,5-, 2,6-DMNB.

Biozidprüfungen

The diols were tested as biocides and, for comparison, propylene glycol (which was used as the solvent), 1,2-pentanediol (high biocidal effect known) and 2,4-pentanediol (low biocidal effect).

For this purpose, a 40 weight percent solution of a diol in propylene glycol at 6O ⁰ C was prepared in each case. This solution was diluted with a double starch soybean solution (double strengh Tryptone Soy Broth) as a nutrient medium in a volume ratio of 1: 1. By further dilution with soybean solution, solutions were prepared with the following concentrations: 400,000 ppm (40%), 200,000 ppm (20%), 10,000 ppm (10%), 50,000 ppm (5%), 25,000 ppm (2.5%). ), 12,500ppm (1.25%), 6,250ppm (0.625%), 3,125ppm (0.3125%)

The following microorganisms were used to test the biocidal activity against different bacteria and fungi: Bacteria:

P. aeruginosa NCIMB 10421

S. aureus NCIMB 9578

E. coli NCIMB 8545

P. vulgaris NCIMB 4175

mushrooms:

C. albicans NCPF 3179

A. niger lMI 149007 As a negative control, pure soybean solution was used. The positive control was a solution of 5 ml soya solution, which was mixed with 0.1 ml of the respective microorganism. The test solutions consisted of 5 ml of the above-described soya solutions of diols of respective concentration, which were mixed with 0.1 ml of the respective microorganism.

The samples and controls were incubated in the case of bacteria at 30 ⁰ C for 48 hours in fungi for 5 days at 25 ° C.

The MIC (Minimum Inhibitory Concentration) value was determined in each case. This value indicates the minimum concentration at which the growth of the microorganisms visibly hindered compared to the corresponding sample without the addition of the diol. The lower the MIC value, the greater the biocidal effect.

A test was considered positive if the test solution was comparable to the positive control by visual assessment. For example, this was recognizable by the appearance of turbidity or visible growth of the microorganism. A test was considered negative if the test solution had the same appearance with the negative control. The MIC value is a range between the next higher concentration of a positive test and the same and / or lower concentration of a first negative test. The last line of the tables below shows a value "Maximum", which indicates the highest measured MIC value of the series of microorganisms tested.
