Description

 "Hair dye"

The present invention relates to the improvement of the intensity of dyeings on keratin fibers, the enhancement of the fastness properties of these dyeings, as well as scalp feel by using at least one active ingredient selected from at least one N-acylsarcosine derivative or at least one N-acyl taurine derivative, or a mixture from the aforementioned active ingredients.

Human hair is today treated in a variety of ways with hair cosmetic preparations. These include, for example, the cleansing of hair with shampoos, the care and regeneration with rinses and cures and the bleaching, dyeing and shaping of the hair with dyes, tinting agents, waving agents and styling preparations. In this case, means for changing or nuancing the color of the head hair play a prominent role. Apart from the bleaching agents that cause an oxidative lightening of the hair by degradation of the natural hair dyes, so in the field of hair coloring essentially four types of hair dyes of importance:

For permanent, intensive colorations with corresponding fastness properties, so-called oxidation colorants are used. Such hair dyes usually contain oxidation dye precursors, so-called developer components and coupler components. The developer components form the actual dyes under the influence of oxidizing agents or of atmospheric oxygen with one another or with coupling with one or more coupler components. The oxidation dyes are characterized by excellent, long-lasting dyeing results. For naturally acting dyeings but usually a mixture of a larger number of oxidation dye precursors must be used; In many cases, direct dyes are still used for shading.

As developer components are usually primary aromatic amines with another, located in the para or ortho position, free or substituted hydroxy or amino group, Diaminopyridinderivate, heterocyclic hydrazones, 4-aminopyrazolone and 2,4,5,6-tetraaminopyrimidine and its derivatives used , Specific representatives are, for example, p-phenylenediamine, p-toluenediamine, 2,4,5,6-tetraaminopyrimidine, p-aminophenol, N, N-bis (2-hydroxyethyl) -p-phenylenediamine, 2- (2,5-) Diaminophenyl) ethanol, 2- (2,5-diaminophenoxy) ethanol, 1-phenyl-3-carboxyamido -amino-pyrazolone-5, 4-amino-3-methylphenol, 2-aminomethyl-4-aminophenol, 2- Hydroxy-4,5,6-triaminopyrimidine, 2,4-dihydroxy-5,6-diaminopyrimidine, 2,5,6-triamino-4-hydroxypyrimidine and 1,3-N, N'-bis (2-hydroxyethyl ) -N, N'-bis (4-aminophenyl) -diamino-propan-2-ol.

As coupler components m-phenylenediamine derivatives, naphthols, resorcinol and resorcinol derivatives, pyrazolones and m-aminophenols are generally used. Suitable coupler substances are, in particular, 1-naphthol, 1,5-dihydroxynaphthalene, 2,7-dihydroxynaphthalene and 1,7-dihydroxynaphthalene, 5-amino-2-methylphenol, m-aminophenol, resorcinol, resorcinol monoethyl ether, m-phenylenediamine, 1 -Phenyl-3-methyl-pyrazolone-5, 2,4-dichloro-3-aminophenol, 1,3-bis (2,4-diaminophenoxy) -propane, 2-chlororesorcinol, 4-chlororesorcinol, 2-chloro-6 -methyl-3-aminophenol, 2-methylresorcinol, 5-methylresorcinol and 2-methyl-5-aminophenol.

For temporary dyeings usually dyeing or tinting agents are used which contain so-called direct drawers as a coloring component. These are dye molecules that grow directly on the hair and do not require an oxidative process to form the color. These dyes include, for example, the henna already known from antiquity for coloring body and hair. These dyeings are generally much more sensitive to shampooing than the oxidative dyeings, so that a much more undesirable nuance shift or even a visible "discoloration" occurs much more quickly.

Finally, another dyeing process has received much attention. In this method, precursors of the natural hair dye melanin are applied to the hair; These then form naturally-analogous dyes in the course of oxidative processes in the hair. Such a process with 5,6-dihydroxyindoline as dye precursor was described in EP-B1-530 229. In particular, multiple use of agents with 5,6-dihydroxyindoline, it is possible to reproduce natural hair color to people with graying hair. The dyeing can be done with atmospheric oxygen as the sole oxidant, so that no further oxidizing agent must be used. In individuals with originally medium blond to brown hair, the indoline can be used as the sole dye precursor. For use in persons with originally red and especially dark to black hair color, on the other hand, satisfactory results can often only be achieved by the concomitant use of further dye components, in particular special oxidation dye precursors.

Another way to stain keratin-containing fibers is through the use of stains containing a combination of component

A compounds containing a reactive carbonyl group with component B compounds selected from (a) CH-acidic compounds and (b) compounds having primary or secondary amino group or hydroxy group selected from primary or secondary aromatic amines, nitrogen-containing heterocyclic compounds and aromatic hydroxy compounds , The corresponding dyeing method (referred to below as oxo dyeing) is described, for example, in the publications WO-A1-99 / 18916, WO-A1 -00 / 38638, WO-A1-01/34106 and WO-A1-01 / 47483. The resulting dyeings have partially color fastness on the keratin-containing fiber, which are comparable to those of the oxidation dyeing. The Nuancenspektrum achievable with the gentle oxo staining is very broad and the color obtained often has an acceptable brilliance and color depth. The aforementioned components A and B, hereinafter referred to as Oxofarbstoffvorprodukte, are generally not themselves dyes, and are therefore each alone taken not for coloring keratin-containing fibers. In combination, they form dyes in a non-oxidative process. However, it is also possible to use corresponding developer and / or coupler-type oxidation dye precursors with or without the use of an oxidizing agent under compounds of component B. Thus, the oxo staining method can be readily combined with the oxidative staining system.

To adjust the pH or to improve the paint lift, the skilled person usually uses ammonia. However, the use of ammonia leads to an undesirable odor during use. Furthermore, the presence of ammonia adversely affects the hair structure. Thus, the skilled artisan has for some time begun to provide low-ammonia color-changing agents.

Although low-ammonia color change agents do not have the aforementioned disadvantages, they lose their tinting strength and color fastness. Therefore, it is a general endeavor to perform the achievable with the known methods dyeings as possible without ammonia and intensify in your color result. A high tinting strength contributes to the profitability of Dyes at. In addition, the dyeings obtained should have a high degree of color fastness, for example against sweat, washing, light or friction and must be compatible with other hair treatment products, in particular in the context of hair care.

It has surprisingly been found that by using at least one representative from the group of N-acylsarcosine derivatives or N-acyltaurine derivatives in color-changing agents, the intensity of hair colorations can be increased and the fastness of the dyeings can be increased. This color intensification offers a general advantage for all color-changing agents, but is particularly surprisingly suitable for low-ammonia color-change agents.

The agents according to the invention preferably contain the substantive dyes in an amount of from 0.01 to 20% by weight, based on the ready-to-use agent.

Furthermore, the preparations of the invention may also naturally occurring dyes such as henna red, henna neutral, henna black, chamomile, sandalwood, black tea, buckthorn bark, sage, bluewood, madder root, Catechu, Sedre and alkano root are included.

It is not necessary for the oxidation dye precursors or the direct dyes to be in each case homogeneous compounds. Rather, in the compositions according to the invention, due to the production process for the individual dyes, minor amounts of other components may be included, as far as they do not adversely affect the dyeing result or for other reasons, e.g. toxicological, must be excluded.

With regard to further optional components as well as the amounts of these components used, reference is expressly made to the relevant manuals known to the person skilled in the art, eg. B. Kh. Schrader, bases and formulations of cosmetics, 2nd edition, Hüthig book publisher, Heidelberg, 1989, referenced.

If the agent according to the invention contains oxidation dye precursors or in particular precursors of a nature-analogous dye based on indole or indoline, the actual oxidative dyeing of the fibers can in principle be carried out with atmospheric oxygen. However, preference is given to using an additional chemical oxidant, preferably in the case of the oxidation dye precursors. When a brightening effect on human hair is desired in addition to coloring with the coloring components, an additional chemical oxidizer is generally used. As a chemical oxidizing agent are persulfates, chlorites and in particular hydrogen peroxide or its addition products of urea, melamine and sodium borate in question.

The compositions according to the invention contain at least one additional chemical oxidizing agent, preferably in an amount of 0.5 to 12.0% by weight, in particular 6 to 12% by weight, in each case based on the weight of the ready-to-use agent. A further embodiment of the agent according to the invention is a coloring agent for keratin-containing fibers, in particular human hair, which is mixed immediately before use of two components, wherein the first component comprises an agent containing in a carrier at least one developer component and optionally at least one

Coupler component and / or at least one substantive dye, the second component is an oxidizing agent composition containing at least one chemical oxidizing agent, in particular hydrogen peroxide, and at least one of the two components comprises at least one compound of the formula (I)

wherein R ¹ , R ² and M are defined as described above, and / or at least one of the two components at least one compound of the formula (II)

wherein R ³ , R ⁴ and M 'are defined as described above. It is preferred according to the invention, when the compounds of formula (I) and / or the formula (II) are both contained in the first component.

Optionally, the agent according to the invention can generally also be applied to the hair together with an oxidation activator which activates the oxidation of the oxidation dye precursors by the oxidizing agent. As mentioned above, the oxidizing agent is atmospheric oxygen or additional chemical oxidizing agents. The oxidation activators are preferably selected from the group consisting of carbonates, hydrogencarbonates, carbamates, carboxylic esters or their salts, aldehydes, in particular aliphatic aldehydes, 1,3-dihydroxyacetone, imidazole and its derivatives, alkali metal and ammonium peroxydisulfates, metal ions, iodides, Quinones and enzymes. The oxidation activators are preferably present in amounts of from 0.01 to 5% by weight, based on the weight of the ready-to-use agent, in the agents according to the invention.

Suitable metal ions are, for example, Zn ²⁺ , Cu ²⁺ , Fe ²⁺ , Fe ³⁺ , Mn ²⁺ , Mn ⁴⁺ , Li ⁺ , Mg ²⁺ , Ca ²⁺ and Al ³⁺ . Particularly suitable are Zn ²⁺ , Cu ²⁺ and Mn ²⁺ . 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 are e.g. Peroxidases that can significantly increase 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, e.g.

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

Glucose oxidase and D-glucose,

Glycerol oxidase and glycerin,

Pyruvate oxidase and pyruvic acid or its salts,

Alcohol oxidase and alcohol (MeOH, EtOH),

Lactate oxidase and lactic acid and their salts,

Tyrosinase oxidase and tyrosine,

Uricase and uric acid or their salts,

Choline oxidase and choline,

Amino acid oxidase and amino acids.

The actual (oxidative) hair dye is expediently prepared immediately before use by mixing the oxidizing agent composition with the carrier of the coloring components, preferably in the weight ratio range of 1: 4 to 4: 1, in particular 1: 2 to 2: 1. The effects according to the invention of the compounds of the formulas (I) and (II) or their combination can be increased in a synergistic manner if the agent according to the invention additionally

The silicone-in-water emulsions which can be used according to the invention can be prepared by known processes, as disclosed, for example, in US Pat. No. 5,998,537 and EP 0 874 017 A1.

In summary, this method of preparation comprises the emulsifying mixture of components, one of which contains at least one polysiloxane, the other of which contains at least one organosilicone material which reacts with the polysiloxane in a chain extension reaction, with at least one metal ion-containing catalyst for the chain extension reaction, at least one surfactant and water present are.

Chain extension reactions with polysiloxanes are known and may include, for example, the hydrosilylation reaction in which an Si-H group having an aliphatically unsaturated group in the presence of a platinum / rhodium catalyst to form polysiloxanes having some Si (C) _P- Si bonds (p = 1-6), the polysiloxanes also being referred to as polysiloxane-polysilalkylene copolymers.

The chain extension reaction may also include the reaction of an Si-OH group (e.g., a hydroxy-terminated polysiloxane) with an alkoxy group (e.g., alkoxysilanes, silicates, or alkoxysiloxanes) in the presence of a metal-containing catalyst to form polysiloxanes. The polysiloxanes used in the chain extension reaction comprise a substantially linear polymer of the following structure: R-Si (R ₂ H-OSi (R ₂ H _n -O-SiR ₃

In this structure, each R independently represents a hydrocarbon radical having up to 20 carbon atoms, preferably having 1 to 6 carbon atoms, such as an alkyl group (for example, methyl, ethyl, propyl or butyl), an aryl group (for example, phenyl), or group required for the chain extension reaction ("reactive group", for example, Si-bonded H atoms, aliphatic unsaturated groups such as vinyl, allyl or hexenyl, hydroxy, alkoxy such as methoxy, ethoxy or propoxy, alkoxy-alkoxy, acetoxy, amino, etc.), with the proviso that on average one to two reactive groups are present per polymer, n is a positive number> 1. Preferably, a plurality of the reactive groups, more preferably> 90%, and especially> 98% of the reactive groups, at the terminal Si -Atomen bound in siloxane. Preferably, n is numbers describing polysiloxanes having viscosities between 1 and 1,000,000 mm ² / s, more preferably viscosities between 1,000 and 100,000 mm ² / s.

The polysiloxanes may be branched to a low degree (for example, <2 mol% of the siloxane units), but the polymers are substantially linear, more preferably fully linear. In addition, the substituents R may in turn be substituted, for example with N-containing groups (for example amino groups), epoxy groups, S-containing groups, Si-containing groups, O-containing groups, etc. Preferably, at least 80% of the radicals R are alkyl radicals, especially preferably methyl groups.

The organosilicone material that reacts with the polysiloxane in the chain extension reaction may be either a second polysiloxane or a molecule that acts as a chain extender. When the organosilicone material is a polysiloxane, it has the above-mentioned general structure. In these cases, one polysiloxane in the reaction has (at least) one reactive group, and a second polysiloxane has (at least) a second reactive group that reacts with the first.

If the organosilicone material comprises a chain-extending agent, it may be a material such as a silane, a siloxane (e.g. disiloxane or trisiloxane) or a silazane. Thus, for example, a composition which comprises a polysiloxane according to the above-described general structure which comprises at least one Si-OH group has been chain extended by reacting with an alkoxysilane (for example, a dialkoxysilane or trialkoxysilane) in the presence of tin or titanium-containing catalysts.

The metal-containing catalysts in the chain extension reaction are usually specific for a particular reaction. Such catalysts are known in the art and include, for example, metals such as platinum, rhodium, tin, titanium, copper, lead, etc. In a preferred chain extension reaction, a polysiloxane having at least one aliphatically unsaturated group, preferably an end group, is reacted with an organosilicone material Presence of a hydrosilylation catalyst which is a siloxane or polysiloxane having at least one (preferably terminal) Si-H group. The polysiloxane has at least one aliphatically unsaturated group and satisfies the general formula given above in which R and n are as defined above, with an average of between 1 and 2 groups R having one aliphatically unsaturated group per polymer. Representative aliphatic unsaturated groups are, for example, vinyl, allyl, hexenyl and cyclohexenyl or a group R ² CH = CHR ³ in which R ^{2 is} a divalent aliphatic silicon-bonded chain and R ^{3 is} a hydrogen atom or an alkyl group. The organosilicone material having at least one Si-H group preferably has the above-mentioned structure, wherein R and n are as defined above and wherein, on average, between 1 and 2 groups R is hydrogen and n is 0 or a positive integer.

This material may be a polymer or a low molecular weight material such as a siloxane (for example, a disiloxane or a trisiloxane).

The polysiloxane having at least one aliphatic unsaturated group and the organosilicone material having at least one Si-H group react in the presence of a hydrosilylation catalyst. Such catalysts are known in the art and include, for example, platinum and rhodium-containing materials. The catalysts may take any known form, for example platinum or rhodium coated on support materials (such as silica gel or activated carbon) or other suitable compounds such as platinum chloride, salts of platinum or chloroplatinic acids. Chloroplatinic acid either as a commercially available hexahydrate or in anhydrous form is a preferred catalyst because of good dispersibility in organosilicone systems and low color change.

In another preferred chain extension reaction, a polysiloxane having at least one Si-OH group, preferably an end group, is added with an organosilicone material Reaction having at least one alkoxy group, preferably a siloxane having at least one Si-OR group or an alkoxysilane having at least two alkoxy groups.

Preferred nonionic surfactants are alkyl polyglycosides of the general formula R ¹ O- (Z) _x . These connections are identified by the following parameters.

The alkyl radical R ¹ 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 using so-called "oxo-alcohols" as starting materials, compounds with an odd number of carbon atoms in the alkyl chain predominate.

The alkyl polyglycosides which can be used according to the invention can contain, for example, only one particular alkyl radical R ¹ . Usually, however, these compounds are prepared starting from natural fats and oils or mineral oils. In this case, the alkyl radicals R are mixtures corresponding to the starting compounds or corresponding to the particular work-up of these compounds.

Particular preference is given to those alkylpolyglycosides in which R ¹ consists essentially of C ₈ and C 10 -alkyl groups, essentially of C ₁₂ and C ₁₄ -alkyl groups, essentially of C ₈ to C ₁₆ -alkyl groups or essentially of C ₂ - To Ci ₆ alkyl groups.

In addition to their surfactant action, the alkyl glycosides can also serve to improve the fixation of fragrance components on the hair. The person skilled in the art will therefore prefer to use this substance class as a further constituent of the preparations according to the invention in the event that an effect of the perfume oil on the hair which exceeds the duration of the hair treatment is desired.

The alkoxylated homologs of said alkyl polyglycosides can also be used according to the invention. These homologs may contain on average up to 10 ethylene oxide and / or propylene oxide units per alkyl glycoside unit.

Furthermore, zwitterionic surfactants can be used, in particular as cosurfactants. Zwitterionic surfactants are those surface-active compounds which carry at least one quaternary ammonium group and at least one -COO * ^" 'or -SO ₃ '^"'group in the molecule. Particularly suitable zwitterionic surfactants are the so-called betaines such as N-alkyl-N, N-dimethylammonium glycinates, for example cocoalkyldimethylammonium glycinate, N-acylaminopropyl-N, N-dimethylammonium glycinates, for example cocoacylaminopropyl-dimethylammonium glycinate, and 2-alkyl-3-carboxylmethyl-3-hydroxyethyl imidazolines having in each case 8 to 18 C atoms in the alkyl or acyl group and the coco acylaminoethylhydroxyethylcarboxymethylglycinate.

The long alkyl chains of the above-mentioned surfactants preferably have 10 to 18 carbon atoms.

Esterquats are known substances which contain both at least one ester function and at least one quaternary ammonium group as a structural element. Preferred esterquats 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 products Armocare ^® VGH-70, a N, N-bis (2-palmitoyloxyethyl) dimethylammonium chloride, as well as Dehyquart ^® F-75 and Dehyquart ^® AU-35 are examples of such esterquats.

The alkylamidoamines are usually prepared by amidation of natural or synthetic fatty acids and fatty acid cuts with dialkylaminoamines. An inventively particularly suitable compound from this group of substances under the name Tegoamid ^® S 18 commercial stearamidopropyl dimethylamine is.

Further cationic surfactants which can be used according to the invention are the quaternized protein hydrolysates.

The compounds used as surfactant with alkyl groups may each be uniform substances. However, it is usually preferred to use native plant or animal raw materials in the manufacture of these substances, so that one can Substance mixtures with different, depending on the particular raw material alkyl chain lengths 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 homologues which are obtained in the reaction of fatty alcohol and alkylene oxide using alkali metals, alkali metal hydroxides or alkali metal alkoxides as catalysts. Narrowed homolog distributions are obtained when, for example, hydrotalcites, alkaline earth metal salts of ether carboxylic acids, alkaline earth metal oxides, hydroxides or alkoxides are used as catalysts. The use of products with narrow homolog distribution may be preferred.

Hair strands of the company Kerling (80% gray, 15 cm long, about 2 g) were used. The tresses were first treated with Poly Blonde Ultrablondierung for 30 min at 32 ° C, rinsed with lukewarm water and finally dried in air and stored for 24 h. The tresses were measured colorimetrically (device Spectraflash 450, software Colortools) with determination of the Lab values of the initial hair.

2.2 Determination of wash fastness:

Each color cream V1, E1, V2 and E2 of Table 1 was mixed with the developer emulsion according to Table 2 in a weight ratio of 1: 1. The finished mixtures were placed on the pretreated strands and rinsed after a contact time of 30 min at 32 ° C. The strands were dried and measured again colorimetrically. To determine the wash fastness, the hair strands were subjected to a washing procedure that simulates hair washing:

An ultrasonic bath is filled with 1% aqueous solution of sodium laureth sulfate (pH 4 to 5) (adjusted with citric acid) and dissolved on 40 ⁰ C heated. The colored hair strands were dipped into the wash solution and sonicated for 15 minutes. This treatment corresponds to the cleaning performance of six washes. Subsequently, the strands were rinsed thoroughly, dried and measured again colorimetrically. The evaluation of the wash fastness was made on the residual color strength of the hair strands, which is calculated on the basis of the recorded measurement data before and after 15 min ultrasonic treatment according to the following formula:

The ΔE values are determined from the measured quantities via the color difference formula in each case from the bleached starting hair.

Residual color strength [%] = ΔE ( _∞ ioπert) / ΔE ( _as- is) ^' 100

The color retention of the dyeings obtained with the compositions according to the invention is greater than with the noninventive formulations.

Table 5: Developer

Before use, each of the color creams E3 to E12 of Table 4 was mixed with the developer emulsion according to Table 5 in a weight ratio of 1: 1.

3.0 open patch test

The open epicutaneous test according to COLIPA (Test Guidelines for the Assessment of Human Skin Tolerance, 1997) is suitable for testing substances and finished products for skin tolerance. Twenty voluntary female and male skin healthy subjects without age limit were included in the test. The creams C1 and C2 of Table 6 were each mixed in a weight ratio of 1 to 1 with the developer EW of Table 6. The above-described mixture of bleaching cream C1 with the developer EW gives an agent according to the invention. The other agent is not according to the invention and was used for comparison.

For each subject, the finished three application mixtures were randomly placed on the forearm inside with a glass rod over a period of 30 minutes every 30 seconds. After the end of the application, the substances were carefully washed off with water from the forearm and the skin areas were dried. The subjects were then checked for redness of the skin. It was also asked if the test subjects feel itching and, if so, on which skin area. The test results are the table 7 and show the number of subjects in percent, who had at least one of the queried skin reactions.
