Description

"Cosmetic agents with increased fragrance intensity and persistence"

The present invention relates to cosmetic compositions for the treatment of the skin and / or scalp and / or hair and / or oral and dental hygiene, in particular deodorant or antiperspirant compositions containing certain silicic acid esters.

The controlled release of ingredients in a variety of preparations, often referred to as "controlled release", is the subject of numerous publications and patent applications. Of great importance in the field of cosmetics is the release of fragrances, since both the product and the substrates treated with the product, such as the skin and / or hair, are to be intensively and long-lasting scented. In addition to the methods of applying perfumes to substrates and coating the perfumed vehicles, or encapsulating perfumes or incorporating into compounds (eg, cyclodextrin-perfume complexes), there is the possibility of chemically binding the perfumes to carrier media, thereby slowly cleaving the chemical bond and the perfume is released. This principle has been realized, for example, in the esterification of perfume alcohols, with a broad state of the art on this group of substances.

There are some proposals in the prior art to bind fragrant alcohols to nonvolatile siloxanes, from which they are slowly released by hydrolysis. Although there is a broad state-of-the-art for siloxane esters of perfume alcohols, there are problems with the use of said compounds in cosmetics. Thus, many of the known compounds in aqueous-based or water-containing cosmetics can not be used, since they already hydrolyze in the product and the delayed release due to this later no longer occurs.

Monomeric orthosilicic esters of perfume alcohols are described, for example, in US 3,215,719 (Dan River Mills). This document also mentions the delayed release of fragrant alcohols from mixed esters such as bis (eugenoxy) diethoxysilane or bis (cinnamoyloxy) diethoxysilane, where the central Si need not necessarily be bound to oxygen only. Oligomeric siloxane esters are not described in this document.

Liquid or pasty soap compositions containing "fragrance-conferring" silicon compounds are described in GB 2041964 (Dow Corning). Also in this document, oligomeric Si compounds having more than one perfume alcohol ester group are not described. Aroma-giving, non-volatile siloxanes of the general formula M _a M ^_'a D _b ^D' _b T _c T ^_'c Q _d where M and ^M' = R ¹ R ² R ³ SIOI _Z2, D and D ^'= R ⁴ R ⁵ SiO _2Z2 , T and T ^' = R ⁶ Si0 _3/2 and Q = SiO _4/2 , wherein R ¹ to R ^{6 are} independently selected from C _1-40 alkyl or alkoxy and aryl or aryl oxy radicals and the indices a, a ^'are positive and one or more of the indices b, b ^' , c, c ^' and d are positive or 0 are described in GB2319527 (General Electric). Formally fall also oligomeric Si compounds with four perfume alcohol ester groups under the general formula, but only compounds are explicitly disclosed in this document, in which at least two carbon atoms are bonded directly to a Si atom. The use of fragrance-giving siloxanes in cosmetics is also not mentioned in this document.

It was therefore still the task to provide siloxane esters of perfume alcohols, which are on the one hand so hydrolyzed that they can be incorporated into aqueous or water-containing cosmetics, without already be subject in the product excessive hydrolysis, but on the other hand are not too resistant to hydrolysis to prevent the consumer from experiencing any fragrance at all during the normal period of use. The substances to be produced should give both the product and the substrates treated with the product (eg skin or hair) a pleasant and long-lasting fragrance. The hydrolysis behavior of the siloxane esters of perfume alcohols is difficult or impossible to predict based on the chemical structure of the perfume alcohols. A further object of the present invention was therefore to enrich the state of the art with a broader range of perfume alcohol siloxane esters having a hydrolysis behavior which is suitable for use.

It has now been found that silicic acid esters containing at least one alcohol radical of a perfume alcohol selected from the group formed by the hexene-1-ols, cinnamyl alcohol, 3-phenylpropan-1-ol (hydrocinnamyl alcohol), 3R (-) - Linalool, 3S (+) - linalool, (-) - menthol, (+) - neo-menthol, α-terpineol, ß-terpineol, γ-terpineol, δ-terpineol, (-) - bomeol, (+) - isobomeol , (-) - Lavandulol, (Z) -4-hepten-2-ol, eugenol, 2-methoxy-4 - ((Z) -1-propenyl) phenol ((Z) -isoeugenol), 2-meth - oxy-4 - ((e) -1-propenyl) phenol ((e) -Isoeugenol), 4-hydroxy-2,5-dimethyl-3 (2H) -furanone (Fura- neol ^®), 4-hydroxy 3-methoxybenzaldehyde (vanillin), 4- (4-hydroxyphenyl) -2-butanone (raspberry ketone), (Z, Z) -3,6-nonadien-1-ol, 3,7-dimethyl-7-octene 1-ol (rhodinol) and (Z) -3-octen-1-ol, which meet the application-technically necessary requirements. In the investigations of these substances it was further surprisingly found that in combination with customary fragrances they also give the fragrances a longer-lasting effect which is not esterified with the oligosilicic acids. Regardless of the chemical composition of the fragrances, the compounds according to the invention can therefore be used in perfume mixtures in order to give the entire perfume composition a prolonged release of fragrance. According to the invention, hexene-1-ols include (Z) -2-hexene-1-ol, (E) -2-hexene-1-ol, (Z) -3-hexene-1-ol (foliar alcohol), (E) 3-hexen-1-ol, (Z) -4-hexen-1-ol, (E) -4-hexen-1-ol and 5-hexen-1-ol understood.

As "other alcohols" which may be present in the transesterification mixture, there are, in particular, perfume alcohols which are different from the group formed by the hexene-1-ols, cinnamyl alcohol, 3-phenylpropan-1-ol (hydrocinnamyl alcohol), 3R (-) - linalool, 3S (+) - linalool, (-) - menthol, (+) - neomenthol, α-terpineol, ß-terpineol, γ-terpineol, δ-terpineol, (-) - borneol, (+ ) -soborneol, (-) - lavandulol, (Z) -4-hepten-2-ol, eugenol, 2-methoxy-4 - ((Z) -1-propenyl) phenol ((Z) -isoeugenol), 2- methoxy-4 - ((e) -1-propenyl) phe nol ((e) -Isoeugenol), 4-hydroxy-2,5-dimethyl-3 (2H) -furanone (furaneol ^®), 4-hydroxy-3 -methoxybenzaldehyde (vanillin), 4- (4-hydroxyphenyl) -2-butanone (raspberry ketone), (Z, Z) -3,6-nonadien-1-ol, 3,7-dimethyl-7-octene-1 -ol (rhodinol) and (Z) -3-octen-1-ol, or biocide alcohols, wherein both individual perfume or biocide alcohols and perfume or Bizidalkoholgemische can be used Depending on the reaction time and conditions, the lower alcohols and an alcohol selected from the group formed by the hexene-1-ols, cinnamyl alcohol, 3-phenylpropan-1-ol (hydrocinnamyl alcohol), 3R (-) - linalool, 3S (+) - linalool, (- ) - Menthol, (+) - neomenthol, α-terpineol, β-terpineol, γ-terpineol, δ-terpineol, (-) - borneol, (+) - isobomoleol, (-) - lavandulol, (Z) -4-heptene 2-ol, eugenol, 2-methoxy-4 - ((Z) -1-propenyl) phenol ((Z) -isoeugenol), 2-methoxy-4 - ((E) -1-propenyl) -phenol ((E) -Isoeugenol), 4-hydroxy-2,5-dimethyl-3 (2H) - furanone (furaneol ^®), 4-hydroxy-3-methoxy-benzaldehyde (vanillin), 4- (4-hydroxyphenyl) -2-butanone non (raspberry ketone), (Z, Z) -3,6-nonadien-1-ol, 3,7-dimethyl-7-octen-1-ol (rhodinol) and (Z) -3-octen-1-ol, and optionally the fragrance or biocide alcohols other than this group, wherein the alcohols are more easily exchanged along Si-O-Si chains or rings than the terminal alcohols. Such transesterifications can be carried out, for example, as described in the publication H. Steinmann, G. Tschernko, H. Hamann, Z. Chem. 3, 1977, pp. 89-92. The content of this publication is expressly considered to be a disclosure of this application for the preparation of silicic acid esters. Usually, the starting materials used are the commercially available silicic acid esters. In particular, the ethanol ester is mentioned here, which can be obtained, for example, from Wacker, Burghausen. The transesterification can be controlled exclusively by increasing the temperature and distilling off the volatile by-products. However, it is preferred if catalysts are used for the transesterification. These are usually Lewis acids, preferably aluminum tetraisopropylate, titanium tetraisopropoxide, silicon tetrachloride or basic catalysts or else preparations such as, for example, aluminum oxide with potassium fluoride. The oligomeric silicic acid esters thus formed then have at least partially perfume alcohol residues and / or biocide alcohol residues or a combination of both. However, the resulting esters usually also contain radicals of lower C 1 -C ₄ -alcohols, such as methanol, ethanol, n-propanol, isopropanol, n-butanol, isobutanol and tert-butanol. As far as small amounts of water or other H-acidic compounds are present in the production of silicic acid esters, an exchange of alcohol residues against OH groups also takes place. Accordingly, the silicic acid ester mixtures according to the invention usually also contain, as radical R, some hydrogen.

Oligokieselsäureester lower C _r C ₄ alcohols such as methanol, ethanol, n-propanol, iso-propanol, n-butanol, iso-butanol and tert-butanol are commercially available, with usually methanol, ethanol, n-propanol, iso-propanol , n-butanol, isobutanol and tert-butanol were used for the esterification. The preparation of not completely transesterified oligosilicic ester leads to silicic acid ester mixtures in which a part of the radicals R is selected from the group methyl, ethyl, n-propyl, iso-propyl, n-butyl, iso-butyl and tert-butyl. Such compounds are preferred in the context of the present invention.

For the purposes of the present invention, the term "perfume alcohols" is understood as meaning fragrances which have free hydroxyl groups which are esterifiable, regardless of how the molecule is developed further. Salicylic acid esters can also be used as perfume alcohols. Under a perfume according to the invention those fragrances, Understood essences and flavors that cause a pleasant sensation of smell in humans and therefore find a variety of uses for the perfuming of technical and sanitary items, soaps, cosmetics, toiletries and the like. According to the invention, the term "fragrances" is understood to mean uniform, defined chemical compounds having an odor and / or taste, ie all substances or mixtures thereof that are perceived by humans and animals as odor meet certain molecular requirements: low molecular weight (max 300) with correspondingly high vapor pressure, surface activity, minimal water and high lipid solubility and weak polarity A strongly hydrophobic and a weakly polar moiety are sufficient to trigger the sensory activity.Also plays the stereochemistry, ie the spatial configuration of the molecules, for the properties of a substance as a fragrance an important role.From the large group of perfume alcohols may be mentioned preferred representatives, in particular (Z) -2-hexen-1-ol, (E) -2-hexene 1-ol, (Z) -3-hexen-1-ol (leaf alcohol), (E) -3-hexen-1-ol, (Z) -4-hexen-1-ol, (E) -4-hex en-1-ol, 5-hexen-1-ol, cinnamyl alcohol, 3-phenylpropan-1-ol (hydrocinnamyl alcohol), 3R (-) - linalool, 3S (+) - linalool, (-) - menthol, (+) -Nomentothol, α-terpineol, β-terpineol, γ-terpineol, δ-terpineol, (-) - borneol, (+) - isoborneol, (-) - lavandulol, (Z) -4-hepten-2-ol, eugenol , 2-methoxy-4 - ((Z) -1-propenyl) phenol ((Z) isoeugenol), 2-methoxy-4 - ((E) -1-propenyl) -phenol ((E) -isoeugenol), 4-hydroxy-2,5-dimethyl-3 (2H) -furanone (furaneol ^®), 4-hydroxy-3-methoxy-benzaldehyde (vanillin), 4- (4-hydroxyphenyl) -2-butanone (raspberry ketone), ( Z, Z) -3,6-nonadien-1-ol, 3,7-dimethyl-7-octen-1-ol (rhodinol), (Z) -3-octen-1-ol, 10-undecene-1 ol, 2,6-dimethylheptan-2-ol, 2-methylbutanol, 2-methylpentanol, 2-phenoxyethanol, 2-phenyl-propan-1-ol, 2-tert-butycyclohexanol, 3,5,5-trimethylcyclohexanol, 3 Hexanol, 3-methyl-5-phenylpentanol, 3-octanol, 4-heptenol, 4-isopropylcyclohexanol, 4-tert-butylcyclohexanol, 6,8-dimethyl-2-nonanol, 6-nonen-1-ol, 9-decene-1-ol, α-methylbenzyl alcohol, amyl salicylate, benzyl alcohol, Ben cylsalicylate, butyl salicylate, citronellol, cyclohexyl salicylate, decanol, dihydromyrcenol, dimethylbenzylcarbinol, dimethylheptanol, dimethyloctanol, ethyl salicylate, ethylvanillin, farnesol, geraniol, heptanol, hexyl salicylate, isoborneol, isopulegol, menthol, myrtenol, n-hexanol, nerol, nona nol, octanol, para-menthane-7-ol, phenylethyl alcohol, phenol, phenyl salicylate, tetrahydrogeraniol, tetrahydrolinalool, thymol, trans-2-cis-6-nonadienol, trans-2-nonen-1-ol, trans-2-octenol and undecanol.

For the purposes of this invention, the lower C 1 -C ₄ -alcohols which have already been mentioned above as customary radicals of the silicic acid esters are not considered to be biocidal alcohols. They are explicitly methyl, ethyl, n-propyl, iso-propyl, n-butyl, isobutyl and tert-butyl alcohol, which are not considered to be biocidal alcohols according to the invention. On the other hand, classical biocides with alcohol functions are expressly regarded as biocide alcohols according to the invention, even if their effect is attributable to other functional groups. For example, various bromphenols and biphenylol, triclosan, chlorothymol, α- (2-ethylhexyl) glycerol ether, 2-methyl-4-phenylbutan-2-ol and quaternary ammonium compounds having at least one long alkyl radical and at least one alkyl radical which is a hydroxy Group bears, to name.

In addition to the silicic acid ester (s), the cosmetic compositions according to the invention may contain at least one further fragrance. As perfume oils or perfumes, according to the invention, individual fragrance compounds, for. As the synthetic products of the ester type, ethers, aldehydes, ketones, alcohols and hydrocarbons are used. Fragrance compounds of the ester type are, for example, benzyl acetate, phenoxyethyl isobutyrate, p-tert-butylcyclohexyl acetate, linalyl acetate, dimethylbenzylcarbinyl acetate (DMBCA), phenylethyl acetate, benzyl acetate, ethylmethylphenylglycinate, allylcyclohexylpropionate, styrallylpropionate, benzylsalicylate, cyclohexylsalicylate, floramate, melusate and jasmecyclate , The ethers include, for example, benzyl ethyl ether and ambroxane, to the aldehydes, for example, the linear alkanals having 8 - 18 carbon atoms, citral, citronellal, citronellyloxy-acetaldehyde, cyclamen aldehyde, lilial and bourgeonal, to the ketones eg the Jonone, alpha-lsomethyl to the alcohols anethole, citronellol, eugenol, geraniol, linalool, phenylethyl alcohol and terpineol, the hydrocarbons mainly include the terpenes such as limonene and pinene. Preferably, however, mixtures of different fragrances are used, which together produce an attractive fragrance.

Such perfume oils may also contain natural fragrance mixtures as are available from vegetable sources, e.g. Pine, citrus, jasmine, patchouly, rose or ylang-ylang oil. Also suitable are Muskateller sage oil, chamomile oil, clove oil, lemon balm oil, mint oil, cinnamon leaf oil, lime blossom oil, juniper berry oil, vetiver oil, olibanum oil, galbanum oil and laudanum oil and orange blossom oil, neroliol, orange peel oil and sandalwood oil.

By dividing the total perfume content in perfume, which is esterified with silicic acid ester, and perfume, which is present without esterification, a variety of product characteristics can be realized. Thus, for example, it is conceivable and possible to divide the total perfume content of the agents according to the invention into two portions x and y, wherein the proportion x of adherent, i. less volatile and the proportion y consists of more volatile perfume oils.

The general description of the perfumes that can be used (see above) generally represents the different substance classes of fragrances. To be perceptible, a perfume must be volatile, wherein besides the nature of the functional groups and the structure of the chemical compound also the molecular weight plays an important role , For example, most odorants have molecular weights up to about 200 daltons, while molecular weights of 300 daltons and above are more of an exception. Due to the different volatility of fragrances, the smell of a perfume or fragrance composed of several fragrances changes during evaporation, whereby the odor impressions in "top note", "middle note or body" As the smell perception is based to a large extent on the odor intensity, the top note of a perfume or fragrance consists not only of volatile compounds, while the base note for the most part from less volatile , ie adherent fragrances stands. For example, in the composition of perfumes, more volatile fragrances can be bound to certain fixatives, preventing them from evaporating too quickly. In the subsequent classification of the fragrances in "more volatile" or "adherent" fragrances so nothing about the olfactory impression and whether the corresponding fragrance is perceived as a head or middle note, nothing said.

Adhesion-resistant fragrances which can be used in the context of the present invention are, for example, the essential oils such as angelica root oil, aniseed oil, arnica blossom oil, basil oil, bay oil, bergamotte oil, Champacablütenöl, Edeltannenöl, Edeltannenzapfen oil, Elemiöl, eucalyptus oil, fennel oil, Fichtennadelöl, galbanum oil, geranium oil, Ginger grass oil, Guajac wood oil, Gurjunbalsam oil, Helichrysum oil, Ho oil, ginger oil, iris oil, cajeput oil, calamus oil, chamomile oil, camphor oil, kananga oil, cardamom oil, cassia oil, pine needle oil, Kopaϊvabalsamöl, coriander oil, spearmint oil, caraway oil, cumin oil, lavender oil, lemongrass oil, lime oil, Tangerine oil, Melissa oil, Musk grain oil, Myrrh oil, Clove oil, Neroli oil, Niaouli oil, Olibanum oil, Orange oil, Origanum oil, Palma pink oil, Patchouli oil, Peru balsam oil, Petitgrain oil, Pepper oil, Peppermint oil, Pimento oil, Pine oil, Rose oil, Rosemary oil, Sandalwood oil, Celery oil, Spiked oil, star aniseed oil, turpentine oil, thuja oil, thymia nöl, verbena oil, vetiver oil, juniper berry oil, wormwood oil, wintergreen oil, ylang-ylang oil, hyssop oil, cinnamon oil, cinnamon oil, lemon oil, lemon oil and cypress oil.

Depending on the field of application of the cosmetic agents, these may contain a large number of further ingredients. These are described below. If the term "agent according to the invention" is used below, this always means the cosmetic agent.

The silicic acid esters according to the invention have their positive effects, in particular during the hair treatment. Usually, in personal care, the skin is cleaned more often than the hair, especially because the hair is expensive to dry and to clean after cleaning. From a hair care product, the consumer therefore wishes a particularly long-lasting care effect. Long-lasting perfuming also signals to the user a lasting effect of the entire product.

Particularly preferred cosmetic compositions according to the invention are characterized in that they are a composition for the treatment of keratin fibers, in particular human hair. Shampoos, conditioning agents, conditioners, hair conditioners, hair tonics, hair lotions, hair gels, hair sprays, etc. are particularly suitable as such. Other important representatives of this group are the hair dyes, especially the oxidation hair dyes.

A further subject of the present invention is therefore the use of a cosmetic composition which, in a suitable cosmetic carrier, comprises silicic acid esters of the formulas I and / or II and / or III and / or IV

each at least one radical R is derived from at least one alcohol selected from the group consisting of (Z) -2-hexen-1-ol, (E) -2-hexen-1-ol, (Z) - 3-hexen-1-ol (leaf alcohol), (E) -3-hexen-1-ol, (Z) -4-hexen-1-ol, (E) -4-hexen-1-ol, 5-hexene 1-ol, cinnamyl alcohol, 3-phenyl-propan-1-ol (hydrocinnamyl alcohol), 3R (-) - linalool, 3S (+) - linalool, (-) - menthol, (+) - neomenthol, α-terpineol, β-terpineol, γ-terpineol, δ-terpineol, (-) - borneol, (+) - isoborneol, (-) - lavandulol, [Z) -A-hepten-2-ol, eugenol, 2-methoxy-4- ((Z) -1-propenyl) phenol ((Z) isoeugenol), 2-methoxy-4 - ((E) -1-propenyl) phenol ((E) -isoeugenol), 4-hydroxy-2,5- dimethyl-3 (2H) -furanone (furaneol ^®), 4-hydroxy-3-methoxy-benzaldehyde (vanillin), 4- (4-hydroxyphenyl) -2-butanone (raspberry ketone), (Z, Z) -3,6 - Nonadien-1-ol, 3,7-dimethyl-7-octene-1-ol (rhodinol) and (Z) contains 3-octene-1-ol, and the other radicals R are each independently selected from the group which is a hydrogen atom, the straight-chain or verzwei GTEN, saturated or unsaturated, substituted or unsubstituted Ci _-6 contains hydrocarbon radicals and the 2-phenoxyethyl radical, and m assumes values from the range 1 to 20 and na value of 2 to 100, and mixtures thereof, for the treatment of Keratin fibers, especially human hair.

Hair shampoos (shampoos) as well as body cleansers (shower baths, shower gels, bath bath compositions, liquid soaps, syndets) may contain (more or less strongly) foaming anionic, zwitterionic, ampholytic and nonionic surfactants. Hair rinse agents, softeners and conditioning skin and body cleansers (2-in-1 shower gels) preferably contain cationic surfactants and / or water-soluble polymers with quaternary ammonium groups to reduce the static chargeability and to improve the combability of the hair or to improve the feel of the skin. Hair and skin cleansers essentially differ only in the amount of surfactant. Because of the lower sensitivity of the hair to the skin, shampoos and similar compositions usually contain more surfactants, in particular more cation surfactants, as skin cleansers. Skin cleansing agents preferably contain 0-2% by weight, more preferably 0-1% by weight, of cationic surfactants. In addition, the mild, less degreasing surfactants are preferably used in skin cleansers. Other hair treatment products contain additives which are rather unsuitable for skin treatment products. For example, permanent wave fixatives preferably contain oxidizing agents, such as. As potassium bromate or hydrogen peroxide. Hair dye shampoos contain direct hair colorants or oxidation dye precursors. Hair fixatives and hair dressings as well as other hair styling preparations usually contain film-forming polymers which are soluble in aqueous or aqueous-alcoholic media, optionally together with cationic surfactants or cationic polymers.

The use of surfactants (E) in the compositions according to the invention has proved to be particularly advantageous. In a further preferred embodiment, the compositions according to the invention therefore contain at least one surfactant. The term surfactants is understood to mean surface-active substances which form adsorption layers on the upper and boundary surfaces or which can aggregate in volume phases to give micelle colloids or lyotropic mesophases. A distinction is made between anionic surfactants consisting of a hydrophobic radical and a negatively charged hydrophilic head group, amphoteric surfactants which carry both a negative and a compensating positive charge, cationic surfactants which, in addition to a hydrophobic radical, have a positively charged hydrophilic group, and nonionic surfactants, which have no charges but strong dipole moments and are highly hydrated in aqueous solution.

Suitable anionic surfactants (E1) in the compositions according to the invention are all anionic surfactants suitable for use on the human body. These are characterized by a water-solubilizing, anionic group, such as. Example, a carboxylate, sulfate, sulfonate or phosphate group, and a lipophilic alkyl group having about 8 to 30 carbon atoms. In addition, glycol or polyglycol ether groups, ester, ether and amide groups and hydroxyl groups may be present in the molecule. Examples of suitable anionic surfactants are, in each case in the form of the sodium, potassium and ammonium as well as the mono-, di- and trialkanolammonium salts having 2 to 4 C atoms in the alkanol group, linear and branched fatty acids having 8 to 30 C atoms (Soap), Ethercarbonsäuren the formula RO- (CH ₂ -CH ₂ O) _x -CH ₂ -COOH ₁ in the R is a linear alkyl group having 8 to 30 carbon atoms and x = O or 1 to 16,

Zwitterionic surfactants (E2) are surface-active compounds which contain in the molecule at least one quaternary ammonium group and at least one -COO * ^'' - or -SO ₃ ^'wear' 'group. Particularly suitable zwitterionic surfactants are the so-called betaines such as N-alkyl-N, N-dimethylammonium glycinates, for example cocoalkyl dimethyl ammonium glycinate, N-acylaminopropyl N, N-dimethylammonium glycinates, for example Kokosacylaminopropyl-dimethylammoniumglycinat, and 2-alkyl-3-carboxymethyl-3-hydroxyethyl imidazoline having in each case 8 to 18 carbon atoms in the alkyl or acyl group and cocoacylaminoethylhydroxyethylcarboxymethylglycinat. A preferred zwitterionic surfactant is the fatty acid amide derivative known by the INCI name Cocamidopropyl Betaine.

Ampholytic surfactants (E3) are understood as meaning those surface-active compounds which contain, in addition to a C ₈ -C ₂₄ -alkyl or -acyl group, at least one free amino group and at least one -COOH or -SO ₃ H group in the molecule and for forming internal Salts are capable.

They can be obtained by the relevant methods of preparative organic chemistry. The alkyl and alkenyl oligoglycosides can be derived from aldoses or ketoses having 5 or 6 carbon atoms, preferably glucose. The preferred alkyl and / or alkenyl oligoglycosides are thus alkyl and / or alkenyl oligoglucosides. The index number p in the general formula (E4-II) indicates the degree of oligomerization (DP), ie the distribution of mono- and oligoglycosides and stands for a number between 1 and 10. While p in the individual molecule must always be integer and here before For all given values p = 1 to 6, the value p for a given alkyloligoglycoside is an analytically determined arithmetic variable, which usually represents a fractional number. Preference is given to using alkyl and / or alkenyl oligoglycosides having an average degree of oligomerization p of from 1.1 to 3.0. From an application point of view, those alkyl and / or alkenyl oligoglycosides are preferred whose degree of oligomerization is less than 1.7, and in particular between 1.2 and 1.4. The alkyl or alkenyl radical R ⁴ can be derived from primary alcohols having 4 to 11, preferably 8 to 10 carbon atoms. Typical examples are butanol, caproic alcohol, caprylic alcohol, capric alcohol and undecyl alcohol and their technical mixtures, as obtained, for example, in the hydrogenation of technical fatty acid methyl esters or in the hydrogenation of aldehydes from Roelen's oxo synthesis.

Sugar surfactants of the fatty acid N-alkylpolyhydroxyalkylamide type, a nonionic surfactant of the formula (E4-III),

R ⁵ CO-NR ⁶ - [Z] (E4-III)

R ^{5 is} CO for an aliphatic acyl radical having 6 to 22 carbon atoms, R ^{6 is} hydrogen, an alkyl or hydroxyalkyl radical having 1 to 4 carbon atoms and [Z] is a linear or branched polyhydroxyalkyl radical having 3 to 12 carbon atoms and 3 to 10 hydroxyl groups stands. The fatty acid N-alkyl polyhydroxyalkylamides are known substances which are usually 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. Preferably, the fatty acid N-alkylpolyhydroxyalkylamides are derived from reducing sugars having 5 or 6 carbon atoms, especially glucose. The preferred fatty acid N-alkylpolyhydroxyalkylamides are therefore fatty acid N-alkylglucamides as represented by the formula R ⁷ CO-NR ⁸ -CH ₂ - (CHOH) ₄ -CH ₂ OH (E4-IV). Glucamides of the formula (E4-IV) in which R ^{8 is} hydrogen or an alkyl group and R ⁷ CO for the acyl radical of caproic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, palmitoleic acid, are preferably used as the fatty acid N-alkylpolyhydroxyalkylamides. Stearic acid, isostearic acid, oleic acid, elaidic acid, petroselinic acid, linoleic acid, linolenic acid, arachidic acid, gadoleic acid, behenic acid or erucic acid or those technical mixtures. Particular preference is given to fatty acid N-alkylglucamides of the formula (E4-IV) which are obtained by reductive amination of glucose with methylamine and subsequent acylation with lauric acid or C 12/14 coconut fatty acid or a corresponding derivative. Furthermore, the polyhydroxyalkylamides can also be derived from maltose and palatinose.

The preferred nonionic surfactants are the alkylene oxide addition products of saturated linear fatty alcohols and fatty acids having in each case 2 to 30 moles of ethylene oxide per mole of fatty alcohol or fatty acid. Preparations having excellent properties are also obtained if they contain fatty acid esters of ethoxylated glycerol as nonionic surfactants. These connections are identified by the following parameters. The alkyl radical R contains 6 to 22 carbon atoms and may be both linear and branched. Preference is given to primary linear and methyl-branched in the 2-position aliphatic radicals. Such alkyl radicals are, for example, 1-octyl, 1-decyl, 1-lauryl, 1-myristyl, 1-cetyl and 1-stearyl. Particularly preferred are 1-octyl, 1-decyl, 1-lauryl, 1-myristyl. When so-called "oxo-alcohols" are used as starting materials, compounds with an odd number of carbon atoms in the alkyl chain predominate.

Furthermore, very particularly preferred nonionic surfactants are the sugar surfactants. These may preferably be present in the agents used according to the invention in amounts of from 0.1 to 20% by weight, based on the total agent. Amounts of 0.5-15% by weight are preferred, and most preferred are amounts of 0.5-7.5% by weight.

The compounds used as surfactant with alkyl groups may each be uniform substances. However, it is generally preferred to use native vegetable or animal raw materials in the production of these substances, so that substance mixtures having different alkyl chain lengths depending on the respective raw material are obtained.

In the case of the surfactants which are adducts of ethylene oxide and / or propylene oxide with fatty alcohols or derivatives of these addition products, both products with a "normal" homolog distribution and those with a narrow homolog distribution can be used. By "normal" homolog distribution are meant mixtures of homologs obtained in the reaction of fatty alcohol and alkylene oxide using alkali metals, alkali metal hydroxides or alkali metal alcoholates as catalysts. Narrowed homolog distributions, on the other hand, are obtained when, for example, hydrotalcites, alkaline earth metal salts of ether carboxylic acids, alkaline earth metal oxides, hydroxides or alcoholates are used as catalysts. The use of products with narrow homolog distribution may be preferred.

Cationic surfactants of the quaternary ammonium compound type, the esterquats and the amidoamines can be used according to the invention. Preferred quaternary ammonium compounds are ammonium halides, in particular chlorides and bromides, such as alkyltrimethylammonium chlorides, dialkyldimethylammonium chlorides and trialkylmethylammonium chlorides, eg. For example, cetyltrimethylammonium chloride, stearyltrimethylammonium chloride, distearyldimethylammonium chloride, lauryldimethylammonium chloride, lauryldimethylbenzylammonium chloride and tricetylmethylammonium chloride, as well as the imidazolium compounds known under the INCI names Quaternium-27 and Quaternium-83. The long alkyl chains of the above-mentioned surfactants preferably have 10 to 18 carbon atoms. According to the invention, preference is given to using QAV with behenyl radicals, in particular the substances known under the name of behentrimonium chloride or bromide (docosanyltrimethylammonium chloride or bromide). Other preferred QAV's have at least two behenyl residues, with QAV being particularly preferred, which are two behenyl residues on an imidazolinium backbone. Commercially available, these substances are, for example, under the names Genamin ^® KDMP (Clariant) and Crodazosoft ^® DBQ (Crodauza).

Esterquats are known substances which contain both at least one ester function and at least one quaternary ammonium group as a structural element. Preferred ester quats are quaternized ester salts of fatty acids with triethanolamine, quaternized ester salts of fatty acids with diethanolalkylamines and quaternized ester salts of fatty acids with 1,2-dihydroxypropyldialkylamines. Such products are marketed under the trade names Stepantex® ^®, ^® and Dehyquart® Armocare® ^®.

The alkylamidoamines are usually prepared by amidation of natural or synthetic fatty acids and fatty acid cuts with dialkylaminoamines. A compound of the invention particularly preferred from this group of substances that available under the designation TEGO amide ^® S 18 commercially stearamidopropyl dimethylamine is.

The metal ions can in principle be used in the form of any physiologically acceptable salt or in the form of a complex compound. Preferred salts are the acetates, sulfates, halides, lactates and tartrates. By using these metal salts, both the formation of the dyeing can be accelerated and the color shade can be specifically influenced. Suitable enzymes include peroxidases, which can significantly enhance the effect of small amounts of hydrogen peroxide. Furthermore, such enzymes are suitable according to the invention which directly oxidize the oxidation dye precursors with the aid of atmospheric oxygen, such as, for example, the laccases, or generate small amounts of hydrogen peroxide in situ and thus biocatalytically activate the oxidation of the dye precursors. Particularly suitable catalysts for the oxidation of the dye precursors are the so-called 2-electron oxidoreductases in combination with the specific substrates, eg

Pyranose oxidase and e.g. D-glucose or galactose,

Glucose oxidase and D-glucose, glycerol oxidase and glycerin,

Usually, coloring agents are offered as a combination pack containing a coloring cream and a separately packaged oxidizing solution. Shortly before use, both components are mixed together and the prepared mixture is applied to the hair to be dyed. The mixing ratio of the two components can be chosen freely. Conveniently, the preparation of the oxidizing agent is then mixed with the preparation with the dye precursors immediately prior to dyeing the hair. The resulting ready-to-use hair dye preparation should preferably have a pH in the range of 6 to 10. Particularly preferred is the use of the hair dye in a weakly alkaline medium. The application temperatures may range between 15 and 40 ° C, preferably at the temperature of the scalp. After a contact time of about 5 to 45, especially 15 to 30, minutes, the hair dye is removed by rinsing of the hair to be dyed. The Nachwaschen with a shampoo is omitted if a strong surfactant-containing carrier, eg. As a dyeing shampoo was used.

Especially with hair that is difficult to dye, the preparation with the dye precursors can be applied to the hair without prior mixing with the oxidation component. After an exposure time of 20 to 30 minutes, the oxidation component is then applied, if appropriate after an intermediate rinse. After a further exposure time of 10 to 20 minutes is then rinsed and nachshampooniert if desired. In this embodiment In accordance with a first variant, in which the previous application of the dye precursors is intended to bring about a better penetration into the hair, the corresponding agent is adjusted to a pH of about 4 to 7. According to a second variant, an air oxidation is initially desired, wherein the applied agent preferably has a pH of 7 to 10. In the subsequent accelerated post-oxidation, the use of acidified peroxydisulfate solutions may be preferred as the oxidizing agent.

Examples of compositions for soaking wipes

Various viscose nonwovens were equipped with these impregnating compositions. Perforated, unperforated, dimpled, single-ply, two-ply and three-ply nonwovens were finished. The wipes were used both as wet wipes and as dry wipes (that is, after finishing, the wipes were dried to a residual water content less than 10 wt%, preferably less than 5 wt%, dried). Example 1 illustrates a lotion composition for a lotion and make-up remover wipe.

Example 2 illustrates a soak composition for a self-tanner cloth.

Example 3 illustrates a soak composition for a sunscreen cloth.

Example 4 illustrates a drenching composition for a facial cleansing and exfoliating wipe.

List of raw materials used

odor tests

For proof of efficacy, a perfume composition P3E was prepared which, in addition to fragrances, contained 1% by weight of (Z) -3-hexenylsilicic acid ester according to claim 1. A comparative perfume composition P3V was identically composed but contained instead of the (Z) -3-hexenylsilicic acid ester according to claim 1 dipropylene glycol in an amount of 1% by weight.

Simulation of fragrance retention in a warm and moist environment (similar to conditions in the forearm)

Equal amounts of each of P3E and P3V perfume compositions were placed on a filter paper. The filter paper was then placed over a half-filled petri dish with water. Care was taken to ensure that the filter paper does not sag and does not come into contact with the liquid in the Petri dish. The Petri dish was covered with a glass funnel, whose funnel tube protruded upwards and was closed. Subsequently, the test set-up at 37 ⁰ C was stored. After every 0, 2, 4, 6 and 24 hours, the cap was briefly removed from the funnel tube and the odor assessed.

At test times 2, 4, 6 and 24 hours, P3E showed a higher fragrance intensity than P3V.

consumer test

Further, deodorant sprays containing either 1% by weight of the perfume composition P3E or P3V were prepared and tested by 50 subjects for 14 days. Test recipe anhydrous deodorant spray (in% by weight)

The final assessment of the deodorant sprays according to a total of 5 criteria is shown in the following table:

Furthermore, subject tests with hair shampoos were carried out. For this purpose, the perfume compositions P4E, P4V, P5E and P5V were prepared:

P4E and P4V were a fragrance composition with a citrus-green perfume profile. P4E also contained (Z) -3-hexenylsilicic acid ester and also citronellylyl silicic acid ester and geranylsilicic acid ester. P4V contained instead of the silicic acid esters an appropriate amount of dipropylene glycol. P5E and P5V were a fragrance composition with a citrus-cosmetic perfume profile. In addition, P5E contained (Z) -3-hexenylsilicic acid ester and also citronellylyl silicic acid ester. P5V contained instead of the silicic acid esters an appropriate amount of dipropylene glycol. Subsequently, shampoos were made with 0.74 wt% P4E or 0.74 wt% P4V, further shampoos with 0.5 wt% P5E or 0.5 wt% P5V tested on 30 subjects , For this purpose, the hairs of the test persons were treated with the test shampoos according to a standardized procedure in the half-side procedure. The hairs of the 30 volunteers were moistened with water and parted to two sides. On the one hand, the formulation of the invention (shampoo with 0.74 wt .-% P4E or shampoo with 0.5 wt.% P5E) and on the other hand, the comparison formulation (shampoo with 0.74 wt .-% P4V or shampoo with 0.5 wt.% P5V). Otherwise, the subjects' hair was treated identically, that is, the shampoos were incorporated into the hair for 1 minute. Then the hair was rinsed thoroughly with water and dried. The assessment was carried out independently by 3 persons of the specialized staff.
