Description

Hair color changing shampoo

The invention relates to a keratin fiber-changing keratin fiber treatment agent, in particular hair color-changing hair treatment agent, which is applied in the form of a foam on the keratin fibers, in particular hair, and a method for dyeing keratin fibers, in particular hair.

The cosmetic treatment of skin and hair is an important part of human body care. For example, 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 colorants, tinting agents, waving agents and styling agents. In this case, means for changing or nuancing the color of the head hair play a prominent role. They may be used to slightly or more intensely nuance the natural hair color according to the desires and needs of the individual, to achieve a completely different hair color, or to mask unwanted color tones, such as shades of gray. Apart from the bleaching agents which cause an oxidative lightening of the hair by degradation of the natural hair dyes, so in the field of hair coloring essentially three types of hair dye are of importance.

For permanent, intensive colorations with corresponding fastness properties, so-called oxidation colorants are used. Such colorants usually contain oxidation dye precursors, so-called developer components and coupler components. The developer components form under the influence of oxidizing agents or of atmospheric oxygen with each other or under coupling with a or more coupler components, the actual dyes. The oxidation stains are characterized by excellent, long lasting staining results. For naturally acting dyeings, a mixture of a larger number of oxidation dye precursors must usually be used.

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 attach directly to the hair and do not require an oxidative process to form the paint. The dye molecules are attached to the cuticle of the hair and are washed away after 6 to 8 washes. These dyes include, for example, the henna already known from antiquity for coloring body and hair.

Finally, recently a novel dyeing behavior 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 has been described in EP-B1-0 530 229. In particular, multiple use of agents with 5,6-dihydroxyindoline, it is possible to reproduce natural hair color to people with graying hair. The coloration 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. On the other hand, satisfactory results can often only be obtained by using further dye components for use in persons with originally red and, in particular, dark to black hair color.

Good dyes are characterized by a high color strength. Furthermore, good welding, heat, perming, washing and light fastness are desired. Furthermore, they should be safe in terms of toxicology and dermatology. It is also from Advantage, if the substances have a high solubility in various base formulations.

More recently, so-called combination preparations have been developed in the field of hair cosmetics, in order to reduce the expense of conventional multistage processes, in particular in the case of direct application by the consumer. These preparations contain, in addition to the usual components, for example for cleaning the hair, additional active ingredients that were formerly reserved for hair aftertreatment agents or hair dyes. The consumer thus saves an application step.

Particularly appreciated by the consumer are hair color changing shampoos with which it is possible to change the hair color during shampooing. Examples of such products are special blond shampoos to give bleached hair additional color reflexes, or so-called silver reflex shampoos to take the unwanted yellowish tinge of gray hair.

Such combination preparations of shampoo and colorant, also known as dyeing shampoo, usually contain direct dyes as colorants. The concentration of substantive dyes is relatively high in these products due to the combination application with a shampoo.

According to the state of the art, combined preparations of shampoo and coloring agent are applied as liquid or gel directly from the tube or bottle to the hair or rubbed beforehand with the hands and then applied to the hair. Due to the fluidity of conventional dyeing shampoos, a limited to the hairy part of the scalp application is not possible. The scalp around the hairline always comes into contact with the dyeing shampoo and becomes stained. Often the use of dye shampoos, especially in the untrained consumer also leads to the staining of other skin areas on the face or eg on the hands. It was therefore an object of the present invention to provide a dyeing shampoo which overcomes the above-mentioned disadvantages and is thus more pleasant to use.

This object is achieved by providing a keratin fiber-color-changing keratin fiber treatment agent, in particular a hair treatment agent, which is applied in the form of a foam to the keratin fibers.

For example, creams, lotions, solutions, waters, emulsions such as W / O, O / W, PIT emulsions (called phase inversion emulsions, PIT), microemulsions and multiple emulsions, gels, sprays, Aerosols and foam aerosols suitable. The pH of these preparations can in principle be between 2 and 11. It is preferably between 3 and 10, with values of 5 to 8 being particularly preferred. To adjust this pH, virtually any acid or base that can be used for cosmetic purposes can be used.

Usually, acids are used as acids. By-acids are understood to mean those acids which are absorbed as part of the usual food intake and have positive effects on the human organism. Eat acids are, for example, acetic acid, lactic acid, tartaric acid, citric acid, malic acid, ascorbic acid and gluconic acid. In the context of the invention, the use of citric acid and lactic acid is particularly preferred.

Preferred bases are ammonia, alkali hydroxides, monoethanolamine, triethanolamine, aminomethylpropanol, triisopropanolamine, and N ₅ N ₅ N ', N'-tetrakis (2-hydroxypropyl) ethylenediamine. These bases also optionally neutralize or partially neutralize, if necessary, fixing and / or fixing polymers used in the compositions.

The preparation of the erfϊndungsgemäßen composition as a lotion, as an aerosol, as a non-aerosol spray lotion, which by means of a mechanical device for Spraying is used, as an aerosol foam or as a non-aerosol foam, which is present in combination with a suitable mechanical device for foaming the composition, is erfmdungsgemäß preferred. A use in the form of a thickened with a conventional thickener aqueous lotion is possible, although not preferred according to the invention.

A very particularly preferred form of application is an aerosol and / or non-aerosol spray application. Here, the agent according to the invention is sprayed by means of a suitable mechanically operated spraying device. By mechanical spraying devices are meant those devices which allow the spraying of a liquid without the use of a propellant. As a suitable mechanical spraying device, for example, a spray pump or provided with a spray valve elastic container in which the cosmetic composition according to the invention is filled under pressure, wherein the elastic container expands and from the means due to the contraction of the elastic container upon opening of the spray valve continuously is used.

If the composition according to the invention is in the form of a hair foam (mousse), it contains at least one customary foaming substance known for this purpose. The agent is foamed with or without the aid of propellants or chemical blowing agents and incorporated as a foam in the hair and rinsed out of the hair after a contact time. The exposure time is usually a few seconds up to 45 minutes. The exposure time depends on the desired result, such as the desired color depth. Preference is given to exposure times of between 30 seconds and 30 minutes. Particularly preferred are exposure times of 30 seconds to 15 minutes.

An inventive hair foam has as an additional component a chemical blowing agent and / or a mechanical device for foaming the composition. By mechanical foaming devices are meant those devices which allow the foaming of a liquid with or without the use of a blowing agent. As a suitable mechanical foaming, for example, a commercially available pump foamer or a Aerosol foam head can be used. These are offered, for example, by the company Airspray under the trade name "Airfoamer." The foaming devices with the trade name "Airfoamer" are particularly preferred. Particularly preferred is the Airfoamer with the type designation G3.

For the embodiment of the invention as an aerosol application, any corresponding aerosol valve can be used, which allows the Sprührate invention. The spray rate is 10 g per second. Preference is given to spraying rates of 5 g per second. Very particular preference is given to spray rates of at least 0.5 g per second and at most 3.5 g per second. It may be advantageous if the valve opening has a diameter of at most 0.4 mm. An opening of 0.35 mm is preferred. Very particularly preferred are valve openings of at most 0.3 mm. Such valves may be commercially available, for example, from the companies Seaquist Perfect Dispensing GmbH or Coster Technology Specials s.p.a. be obtained.

To use the compositions of the invention as aerosol sprays propellants must be used. The propellants preferred according to the invention are selected from the hydrocarbons having 3 to 5 carbon atoms, such as propane, n-butane, isobutane, n-pentane and iso-pentane, dimethyl ether, carbon dioxide, nitrous oxide, fluorocarbons and chlorofluorocarbons and mixtures of these substances. Very particularly preferred propellants are propane, butane, isobutane, pentane, isopentane, dimethyl ether and the mixtures of these aforementioned propellant gases in each case with each other. According to the invention most preferred propellants are the mixtures of dimethyl ether with hydrocarbons. Within the group of hydrocarbons as propellant gases are preferred n-butane and propane.

Advantageously, the blowing agent is selected so that it can simultaneously serve as a solvent for other ingredients such as perfume oils, oil and wax components, the fatty substances (D), the dye precursors or substantive dyes. The propellant can then serve as a solvent for these latter components, if they are at 20 ⁰ C to at least 0.1 wt .-%, based on the propellant, in this soluble. According to a preferred embodiment, the preparations according to the invention contain the said hydrocarbons or mixtures of said hydrocarbons with dimethyl ether as sole blowing agent. However, the invention expressly also includes the concomitant use of propellant of the type of chlorofluorocarbons, but especially the fluorocarbons.

The propellant gases are present in amounts of 5 to 98% by weight, preferably 10 to 98% by weight and more preferably 20 to 98% by weight, very particularly preferably 40 to 98% by weight, based in each case on the total aerosol composition ,

The compositions of the invention may be packaged in commercial aerosol cans. The cans can be tinplate or aluminum. Furthermore, the cans can be internally coated to minimize the risk of corrosion.

For further embodiment, expressly referred to Andreas Domsch, "The cosmetic preparations", Volume II, Chapter 4, aerosols, page 259 following, published by the Chemical Industry, H. Ziolkowsky Kg, Augsburg, 1992. According to the invention, it is understood that the Aerosol container from Alumonoblocdosen, but also from plastics such as PET or glass can be.

For the embodiment of the invention as a non-aerosol, any spray pump can be used, which allows the erfmdungsgemäße spray rate. Corresponding systems are commercially available from Calmar Inc., for example.

Hair treatment agent which is applied in the form of a foam on the keratin fibers, especially hair. The dependent claims represent preferred embodiments of this Erfmdungsgegenstandes. Another object of the invention is a process for dyeing keratin fibers, in particular hair fibers.

In the context of the investigations on which the present invention is based, it has surprisingly been found that dyeing shampoos, which are applied as foam, lead to a markedly reduced staining of the skin on contact with the skin and, moreover, by targeted application largely avoid undesired skin contact and thus staining of the skin.

The keratin fiber treatment agents according to the invention, in particular

Hair treatment agent can be applied with a conventional mechanical pump foam system, a pump foamer, or with a propellant from a conventional aerosol pressure vessel on the hair.

The agents according to the invention may contain, in addition to coloring active ingredients, also cleansing and nourishing agents.

Suitable coloring agents are, in particular, natural and synthetic substantive dyes and precursors of naturally-analogous dyes.

Direct dyes are usually nitrophenylenediamines, nitroaminophenols, azo dyes, anthraquinones or indophenols. Particularly suitable substantive dyes are those under the international designations or trade names HC Yellow 2, HC Yellow 4, HC Yellow 5, HC Yellow 6, Basic Yellow 57, Disperse Orange 3, HC Red 3, HC Red BN, Basic Red 76, HC Blue 2, HC Blue 12, Disperse Blue 3, Basic Blue 99, HC Violet 1, Disperse Violet 1, Disperse Violet 4, Disperse Black 9, Basic Brown 16 and Basic Brown 17 known compounds as well as 1,4-bis (.beta.-hydroxyethyl ) - amino-2-nitrobenzene, 4-amino-2-nitrodiphenylamine-2'-carboxylic acid, 6-nitro-1,2,3,4-tetrahydroquinoxaline, hydroxyethyl-2-nitro-toluidine, picramic acid, 2-amino-6 chloro-4-nitrophenol, 4-ethylamino-3-nitrobenzoic acid and 2-chloro-6-ethylamino-1-hydroxy-4-nitrobenzene. Directly acting dyes found in nature include, for example, henna red, henna neutral, chamomile flower, sandalwood, black tea, buckthorn bark, sage, sawnwood, madder root, catechu, sedre and alkana root.

For example, indoles and indolines and their physiologically acceptable salts are used as precursors of naturally-analogous dyes. Preference is given to using those indoles and indolines which have at least one hydroxyl or amino group, preferably as a substituent on the six-membered ring. These groups may carry further substituents, e.g. Example in the form of etherification or esterification of the hydroxy group or alkylation of the amino group. Particularly advantageous properties have 5,6-dihydroxyindoline, N-methyl-5,6-dihydroxyindoline, N-ethyl-5,6-dihydroxyindoline, N-propyl-5, 6-dihydroxyindoline, N-butyl-5,6-dihydroxyindoline, 5,6-dihydroxyindoline-2-carboxylic acid, 6-hydroxyindoline, 6-aminoindoline and 4-aminoindoline and 5,6-dihydroxyindole, N-methyl-5,6-dihydroxyindole, N-ethyl-5,6-dihydroxyindole, N- Propyl 5,6-dihydroxyindole, N-butyl-5,6-dihydroxyindole, 5,6-dihydroxyindole-2-carboxylic acid, 6-hydroxyindole, 6-aminoindole and 4-aminoindole.

The indoline and indole derivatives in the colorants used in the process according to the invention both as free bases and in the form of their physiologically acceptable salts with inorganic or organic acids, eg. As the hydrochlorides, sulfates and hydrobromides are used.

When dye precursors of the indoline or indole type are used, it may be preferable to use them together with at least one amino acid and / or at least one oligopeptide. Preferred amino acids are aminocarboxylic acids, in particular α-aminocarboxylic acids and ω-aminocarboxylic acids. Among the α-aminocarboxylic bonsäuren arginine, lysine, ornithine and histidine are again particularly preferred. A very particularly preferred amino acid is arginine, especially in free form, but also used as the hydrochloride.

Both the substantive dyes and the precursors of naturally-analogous dyes are preferably present in the agents according to the invention in amounts of 0.01-20% by weight, preferably 0.1-5% by weight, in each case based on the total agent.

The compositions according to the invention may furthermore contain detergent active substances, in particular surfactants used as washing raw materials.

The term "surfactants" is understood as meaning 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 strongly hydrated in aqueous solution.

The alkyl and alkenyl oligoglycosides can be derived from aldoses or ketoses with 5 or 6 carbon atoms, preferably glucose. The preferred alkyl and / or alkenyl oligoglycosides are thus alkyl and / or alkenyl oligoglucosides.

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 using so-called "oxo-alcohols" 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.

The surfactants (E) are used in amounts of 0.1-45% by weight, preferably 0.5-30% by weight and very particularly preferably 0.5-25% by weight, based on the total agent used according to the invention ,

Also usable according to the invention are cationic surfactants (E5) of the quaternary ammonium compound type, the esterquats and the amidoamines. Preferred quaternary ammonium compounds are ammonium halides, especially chlorides and bromides, such as alkyltrimethylammonium chlorides, dialkyldimethylammonium chlorides and trialkylmethylammonium chlorides, e.g. As cetyltrimethylammonium chloride, stearyltri- methylammonium chloride, distearyldimethylammonium chloride, lauryldimethylammonium chloride, lauryldimethylbenzylanimonium 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.

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 products Armocare ^® VGH-70, a N, N-bis (2-Palmitoyloxy- ethyl) dimethyl ammonium chloride, as well as Dehyquart ^® F-75, Dehyquart ^® C-4046, Dehyquart ^® L80 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 is that available under the name Tegoamid ^® S 18 commercially stearamidopropyl dimethylamine.

The cationic surfactants are contained in the compositions according to the invention preferably in amounts of 0.05 to 10 wt .-%, based on the total agent. Amounts of 0.1 to 5 wt .-% are particularly preferred.

Anionic, nonionic, zwitterionic and / or amphoteric surfactants and mixtures thereof may be preferred according to the invention.

The emulsifiers required as follows are also to be included among the surfactants and / or emulsifier components which are compulsory according to the invention: emulsifiers effect the formation of water- or oil-stable adsorption layers at the phase interface, which protect the dispersed droplets against coalescence and thus stabilize the emulsion. Emulsifiers are therefore constructed like surfactants from a hydrophobic and a hydrophilic part of the molecule. Hydrophilic emulsifiers preferably form O / W emulsions and hydrophobic emulsifiers preferably form W / O emulsions. An emulsion is to be understood as meaning a droplet-like distribution (dispersion) of a liquid in another liquid under the expense of energy in order to create stabilizing phase interfaces by means of surfactants. The selection of these emulsifying surfactants or emulsifiers depends on the substances to be dispersed and the respective outer phase and the fineness of the emulsion.

According to a preferred embodiment for use on the hair, these preparations are formulated as a hair conditioner or hair conditioner. The preparations according to the invention in accordance with this embodiment can be rinsed out after expiry of this reaction time with water or an agent which is at least predominantly hydrous; however, they are preferably left on the hair as stated above. It may be preferred to apply the fiction, contemporary preparation prior to the application of a cleaning agent, a waving agent or other hair treatment agents on the hair. In this case, the erfmdungsgemäße preparation serves as a color protection for the following applications.

In a particular embodiment of the compositions according to the invention, it may be preferred if the agents are present as a microemulsion. Within the scope of the invention, microemulsions are also understood as meaning "PIT" emulsions. These emulsions are in principle systems with the three components water, oil and emulsifier, which at room temperature are known as oil-in-water (O / W). When these systems are heated, microemulsions form in a certain temperature range (commonly referred to as the phase inversion temperature or "PIT") which, on further heating, convert to water-in-oil (W / O) emulsions. Upon subsequent cooling, O / W emulsions are again formed, but they are also present at room temperature as microemulsions having an average particle diameter of less than 400 nm, in particular having a particle diameter of about 100 to 300 nra. Details regarding these very stable, low-viscosity systems, for which the term "PIT emulsions" has become generally accepted, can be found in a large number of publications, for which the publications in US Pat Angew. Chem. 97, 655-669 (1985) and Adv. Colloid Interface, pages 58, 119-149 (1995).

According to the invention, preference may be given to those microparticles or "PIT" emulsions which have an average particle diameter of about 200 nm.

The preparation of the microemulsions according to the invention can be carried out, for example, by first determining the phase inversion temperature of the system by heating a sample of the conventionally prepared emulsion and using a conductivity meter to determine the temperature at which the conductivity decreases sharply. The decrease in the specific conductivity of the initially present O / W emulsion generally decreases over a temperature range from 2 to 8 ° C. from initially more than 1 mS / cm to values below 0.1 mS / cm. This temperature range then corresponds to the phase inversion temperature range. Thus, after the phase inversion temperature range is known, the emulsion of oil component, nonionic emulsifier, at least parts of the water and optionally other components initially prepared as usual can be heated to a temperature which is within or above the phase inversion temperature range, then allowed to cool and optionally add other components as well as the remaining water. Alternatively, the preparation of the microemulsion may be carried out directly at a temperature which is within or above the phase inversion temperature range. The microemulsion thus prepared is then cooled to a temperature below the phase inversion temperature range, usually room temperature.

The term dyeing process comprises all processes known to those skilled in the art, in which a colorant is applied to the hair, which may have been moistened, and left on the hair either for a period of a few minutes to about 45 minutes and then with water or a surfactant-containing agent is rinsed or left completely on the hair. It is in this context explicitly on the known monographs, z. B. Kh. Schrader, Basics and Recipes of cosmetics, 2nd edition, Hüthig book Verlag, Heidelberg, 1989, referenced, reflect the corresponding knowledge of the expert.

Direct dyes found in nature include, for example, henna red, henna neutral, henna black, chamomile flower, sandalwood, black tea, buckthorn bark, sage, sawnwood, madder root, catechu, sedre and alcano root.

It is not necessary that the oxidation dye precursors or the direct dyes each represent uniform compounds. Rather, in the hair colorants according to the invention, due to the production process for the individual dyes, in minor amounts, other components may be included, as far as they do not adversely affect the dyeing result or for other reasons, eg. As toxicological, must be excluded.

With regard to the dyes which can be used in the hair-dyeing and tinting compositions according to the invention, reference is expressly made to the monograph Ch. Zviak, The Science of Hair Care, Chapter 7 (pages 248-250, direct dyes) and chapter 8, pages 264-267; Oxidation dye precursors), published as Volume 7 of the series "Dermatology" (Editor: Ch., Culnan and H. Maibach), published by Marcel Dekker Inc., New York, Basel, 1986, and the European Inventory of Cosmetic Raw Materials ", published by the European Community, available in disk form from the Federal Association of German industrial and commercial companies for pharmaceuticals, health products and personal care registered association, Mannheim, reference is made.

For example, indoles and indolines and their physiologically acceptable salts are used as precursors of naturally-analogous dyes. Preference is given to using those indoles and indolines which have at least one hydroxyl or amino group, preferably as a substituent on the six-membered ring. These groups may carry further substituents, e.g. Example in the form of etherification or esterification of the hydroxy group or alkylation of the amino group. Particularly advantageous properties have 5,6-dihydroxyindoline, N-methyl-5,6-dihydroxyindoline, N-ethyl-5,6-dihydroxyindoline, N-propyl-5, 6-dihydroxyindoline, N-butyl-5,6-dihydroxyindoline, 5, 6-dihydroxyindoline-2-carboxylic acid, 6-hydroxyindoline, 6-aminoindoline and 4-aminoindoline and also 5,6-dihydroxyindole, N-methyl-5,6-dihydroxyindole, N-ethyl-5,6-dihydroxyindole, N- propyl 5,6-dihydroxyindole, N-butyl-5,6-dihydroxyindole, 5,6-dihydroxyindole-2-carboxylic acid, 6-hydroxyindole, 6-aminoindole and 4-aminoindole.

Particularly noteworthy within this group are N-methyl-5,6-dihydroxyindoline, N-ethyl-5,6-dihydroxyindoline, N-propyl-5,6-dihydroxyindoline, N-butyl-5,6-dihydroxy-indoline and in particular the 5,6-dihydroxyindoline and N-methyl-5,6-dihydroxyindole, N-ethyl-5,6-dihydroxyindole, N-propyl-5,6-dihydroxyindole, N-butyl-5,6-dihydroxyindole and in particular 5, 6-dihydroxyindole.

The indoline and indole derivatives in the colorants used in the process according to the invention both as free bases and in the form of their physiologically acceptable salts with inorganic or organic acids, eg. As the hydrochlorides, sulfates and hydrobromides are used.

When using dye precursors of the indoline or indole type, it may be preferable to use them together with at least one amino acid and / or at least one oligopeptide. Preferred amino acids are aminocarboxylic acids, in particular α-aminocarboxylic acids and ω-aminocarboxylic acids. Among the α-aminocarboxylic acids, in turn, arginine, lysine, ornithine and histidine are particularly preferred. A very particularly preferred amino acid is arginine, especially in free form, but also used as the hydrochloride.

Hair dyes, especially when the dyeing is oxidative, whether with atmospheric oxygen or other oxidizing agents such as hydrogen peroxide, are usually adjusted to slightly acidic to alkaline, ie to pH values in the range of about 5 to 11. For this purpose, the colorants contain alkalizing agents, usually alkali metal or alkaline earth metal hydroxides, ammonia or organic amines. Preferred alkalizing agents are monoethanolamine, monoisopropanolamine, 2-amino-2-methyl-propanol, 2-amino-2-methyl-1,3-propanediol, 2-amino-2-ethyl-1,3-propanediol, 2-amino-2 -methylbutanol and triethanolamine and alkali and alkaline earth metal hydroxides. In particular monoethanolamine, triethanolamine and 2-amino-2-methyl-propanol and 2-amino-2-methyl-l, 3-propanediol are preferred within the scope of this group. Also the Use of ω-amino acids such as ω-aminocaproic acid as alkalizing agent is possible.

If the formation of the actual hair dyes takes place in the context of an oxidative process, conventional oxidizing agents, in particular hydrogen peroxide or its addition products of urea, melamine or sodium borate can be used. However, oxidation with atmospheric oxygen as the sole oxidant may be preferred. Furthermore, it is possible to carry out the oxidation by means of enzymes, which enzymes are used both for the production of oxidizing per- compounds and for enhancing the effect of a small amount of existing oxidizing agents, or enzymes, the electrons from suitable developer components (reducing agent) Transmitted atmospheric oxygen. Oxidases such as tyrosinase, ascorbate oxidase and laccase but also glucose oxidase, uricase or pyravate oxidase are preferred. Furthermore, the procedure is called to increase the effect of small amounts (eg, 1% and less, based on the total agent) of hydrogen peroxide by peroxidases.

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 from 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. After washing with a shampoo deleted if a strong surfactant-containing carrier, eg. As a dyeing shampoo was used.

Furthermore, the formation of the coloration can be supported and increased by adding certain metal ions to the agent. Such 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 ⁺ and Mn ⁺ . The metal ions can in principle in the form be used of any physiologically acceptable salt. 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.

In a preferred embodiment of the invention, the hair color-changing agent is present as a shampoo.
