Description

The present application relates to colorants for keratin fibers, comprising, in addition to substantive dyes and / or dye precursors, at least one fatty acid glyceryl ester and at least one specific cationic surfactant and ammonium bicarbonate.Human hair is nowadays treated in a variety of ways with hair cosmetic preparations. These include, for example, the cleansing of the hair with shampoos, the care and regeneration with rinses and courses, and the bleaching, coloring and shaping of the hair with colorants, tints, waving agents and styling preparations. Agents for changing or nuancing the color of the hair head play an outstanding role.For temporary dyeings, dyeing or toning agents are usually used which contain so-called direct dyes as the coloring component. These are dye molecules which are drawn directly onto the hair and do not require an oxidative process for forming the color. These dyes include, for example, the henna already known from the old literature for coloring bodies and hair. These dyeings are generally much more sensitive to shampooing than the oxidative dyeings, so that a often undesirable shade shift or even a visible "discoloration" then occurs very much more quickly.For permanent intensive dyeings having corresponding fastness properties, so-called oxidation dyeing agents are used. Such colorants 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 atmospheric oxygen with one another or with coupling with one or more coupler components. The oxidation dyeing compositions are distinguished by excellent, long-lasting dyeing results. For naturally acting dyeings, it is usually necessary to use a mixture of a relatively large number of oxidation dye precursors; in many cases, direct dyes are furthermore used for shading.Finally, a novel coloring method has recently attracted great attention. In this method, precursors of the natural hair dye melanin are applied to the hair; these then form natural-analogous dyes in the hair within the scope of oxidative processes. Such a process with 5,6-dihydroxyindoline as the dye precursor has been described in EP-B1-530 229. When, in particular, agents with 5,6-dihydroxyindoline are used several times, it is possible to reproduce the natural hair color for people with grayed hair. The staining can be carried out with atmospheric oxygen as the only oxidizing agent, so that no further oxidizing agents have to be used. For individuals with originally medium-bloned to brown hair, the indoline can be used as the sole dye precursor. For use in persons with originally red and in particular dark to black hair color, satisfactory results, on the other hand, can frequently only be achieved by the use of further dye components, in particular special oxidation dye precursors.Hair colorants are usually formulated in the form of aqueous emulsions or coloring gels, which are optionally mixed with an oxidizing agent preparation immediately before use. When hair colorants are formulated in the form of emulsions, problems with storage stability are frequently observed owing to the very high salt content of the formulations, in some cases. The salt content can result, inter alia, from the dye precursors frequently used in the form of the more storage-stable salts and salt additions which originate from the production process, in particular in the case of substantive dyes.In order to improve the condition of care of the fibers, it has long been customary to subject the fibers to a special post-treatment following the color-changing treatment. In this case, the hair is treated, usually in the form of a rinse, with specific active ingredients, for example quaternary ammonium salts or specific polymers. Depending on the formulation, the combing, holding and filling of the hair are improved by this treatment and the filling rate is reduced.Recently, so-called combination preparations have also been developed in order to reduce the expenditure of the usual multistage processes, in particular in the direct application by consumers.In addition to the usual components, for example for dyeing the hair, these preparations additionally contain active ingredients which were previously reserved for the hair after-treatment agents. The consumer thus saves one application step; at the same time, the packaging effort is reduced since a product is less needed.The active compounds which can be used in the context of such combination preparations must satisfy high demands, in particular with regard to their stability, since the coloring creams usually have a high pH and the oxidizing agent preparations have a low pH. Furthermore, incompatibilities of the various active ingredients with one another and thus a low storage stability are to be avoided.Within the scope of the applications DE-A-199 14 927, DE-A-199 14 926 and DE-A-44 08 506, such active compound combinations have already been proposed for use in oxidative colorants. DE 199 01 886 A1 describes a process for the preparation of a hair dye which is in the form of a stable aqueous emulsion and which contains, inter alia, water-soluble surfactants, salts and fatty phase components. US 2004 / 0019980 A1 relates to hair care compositions with more effective ways of forming dyes, which compositions comprise a water-soluble peroxide, an oxidation dye and a water-soluble carbonate. Nevertheless, these compositions, especially on fibers which are difficult to care, such as, for example, Japanese hair, still leave some desires with regard to the care properties.There is therefore still a need for cream bases for the color-changing treatment of fibers with good care properties and good stability even in the case of formulations having a high salt content.It has now surprisingly been found that colorants which, in addition to the coloring components, comprise at least one fatty acid glyceryl ester and at least one specific cationic surfactant and ammonium bicarbonate are extraordinarily stable despite high salt contents and furthermore exhibit an excellent care effect.The present application therefore relates first to an agent for coloring keratin fibers, which comprises (A) at least one dye precursor and / or one direct dye (B) at least one fatty acid glyceryl ester and (C) at least one cationic surfactant of the formula (I) where the radicals R 1 to R 4 independently of one another represent a C 1- to C 4- alkyl chain or a C 10- to C 30- alkyl chain, with the proviso, wherein at least one and at most two of the radicals R 1 to R 4 are a C 12- to C 30- alkyl chain, and X is a physiologically tolerable anion, (D) ammonium bicarbonate.Although in principle the co-use of classic thickeners is not ruled out, it is possible with the cream base according to the invention to completely dispense with this class of compounds.It has also been found that the cream base according to the invention enables a very good build-up capacity for the dye (precursor)s on the hair, ensures a very good length compensation of the dyeing, and the fibers shine after the treatment. The use of ammonium bicarbonate leads to a constantly good coloring performance of the coloring cream both over longer storage periods and over longer periods of use.Keratin fibers are understood according to the invention to mean fur, wool, feathers and in particular human hair.With regard to the further dye precursors usable in the colorants according to the invention, the present invention is not subject to any restrictions at all.

On the contrary, the hair colorants according to the invention, as a result of the production processes for the individual dyes, can also contain minor amounts of further components, provided these do not have a disadvantageous effect on the coloring result or have to be excluded for other reasons, for example toxicological reasons.With regard to the dyes which can be used in the hair dyeing and dyeing compositions according to the invention, reference is also expressly made to the monograph Ch. Zviak, The Science of Hair Care, Chapter 7 (pages 248-250; substantive dyes) and Chapter 8, pages 264-267; oxidation dye precursors), published as Volume 7 of the Dermatology series (ed.: Ch., Culnan and H. Maybach), Marcel Dekker Inc., New York, Basle, 1986, and the European Inventory of Cosmetic Raw Materials, edited by the European Community, available in Federal Association Deutscher Industrial and Trade Companies for Drugs, Reformware and Personal Care Products e.V., Mannheim.As a second component essential to the invention, the colorants contain at least one fatty acid glyceryl ester. Fatty acid glyceryl esters preferred according to the invention are the so-called fatty acid partial glycerides, in particular monoglycerides, diglycerides and technical mixtures thereof. When technical products are used, small amounts of triglycerides may still be present due to the production process.Preferred fatty acid glyceryl esters are therefore the compounds of the formula (III), in which R 1, R 2 and R 3 independently of one another represent hydrogen or a linear or branched, saturated and / or unsaturated acyl radical having 6 to 22, preferably 12 to 18, carbon atoms, with the proviso that at least one of these groups represents an acyl radical and at least one of these groups represents hydrogen. The sum (m+n+q) is 0 or numbers from 1 to 100, preferably 0 or 5 to 25, very particular preference being given to the compounds of the formula (III) in which the sum (m+n+q) is 0. Particular preference is given to compounds of the formula (III) in which R 1 is an acyl radical and R 2 and R 3 are hydrogen. Typical examples are mono- and / or diglycerides based on caproic acid, caprylic acid, 2-ethylhexanoic acid, capric acid, lauric acid, isotridecanoic acid, myristic acid, palmitic acid, palmoleic acid, stearic acid, isostearic acid, oleic acid, elaidic acid, petroselic acid, linoleic acid, linolenic acid, elaeostearic acid, arachidonic acid, gadoleic acid, behenic acid and erucic acid and technical mixtures thereof.

Oleic acid monoglycerides and stearic acid monoglycerides are fatty acid glyceryl esters which are very particularly preferred according to the invention.The fatty acid glyceryl esters are preferably present in the agents according to the invention in amounts of from 0.1 to 10 wt %, in particular from 0.3 to 3 wt %.As a third obligatory component, the compositions according to the invention comprise at least one specific cationic surfactant of the formula (I) where the radicals R 1 to R 4 independently of one another represent a C 1- to C 4- alkyl chain or a C 10- to C 30- alkyl chain, with the proviso that at least one and at most two of the radicals R 1 to R 4 represent a C 12- to C_NER273 alkyl chain, and X represents a physiologically tolerable anion.Preferred C 1- to C 4- alkyl chains in the sense of the formula (I) are methyl, ethyl, propyl, isopropyl and butyl groups, the methyl group being particularly preferred according to the invention.Preferred C 10- to C 30- alkyl chains in the sense of the formula (I) are the capric, cetyl, stearyl, behenyl and lauryl groups. According to the invention, C 12- to C 30- alkyl chains may be particularly preferred. The cetyl and behenyl groups are very particularly preferred according to the invention.Preferred physiologically compatible anions X for the purposes of the present invention are both inorganic anions, such as, for example, the halides (chloride, bromide, iodide), the sulfate and the phosphate, and organic anions, such as, for example, the acetate and the lactate. A further anion in the context of the present invention is the methosulfate anion. The chloride and the bromide are particularly preferred according to the invention, very particularly preferred according to the invention is the chloride.Preferred compounds of formula (I) are the alkyltrimethylammonium chlorides, dialkyldimethylammonium chlorides, alkyltrimethylammonium bromides and dialkyldimethylammonium bromides. Very particularly preferred compounds of the formula (I) are dicaprine dimethyl ammonium chloride, lauryl trimethyl ammonium chloride, cetyl trimethyl ammonium chloride, stearyl trimethyl ammonium chloride, distearyl dimethyl ammonium chloride, dicetyl dimethyl ammonium chloride, dilauryl dimethyl ammonium chloride, behenyl trimethyl ammonium chloride and behenyl trimethyl ammonium methosulfate. Furthermore, mixtures of the compounds mentioned, in particular naturally occurring mixtures, such as, for example, the derivatives of tallow fatty alcohol, may also be preferred according to the invention. As representatives, ditallow dimethyl ammonium chloride and monotallow trimethyl ammonium chloride may be mentioned explicitly at this point.The cationic surfactants of the formula (I) are present in the agents used according to the invention preferably in amounts of from 0.05 to 10% by weight, based on the total agent. Amounts of from 0.1 to 5% by weight are particularly preferred.As a fourth component essential to the invention, the colorants contain ammonium bicarbonate.Ammonium bicarbonate (NH 4) HCO 3, ( also referred to as ammonium bicarbonate or double carbon ammonium) is commercially available in the form of large glossy, hard, colorless, almost odorless prisms. Preferred agents according to the invention contain, based on the weight of the agent, 0.1 to 10 wt %, preferably 0.25 to 8 wt %, particularly preferably 0.5 to 5 wt % and in particular 1 to 3 wt % ammonium bicarbonate.In addition, the colorants may contain silica."Silica" in the context of the present application is the collective term for compounds of the general formula (SiO 2)m · nH 2 O. If a silicon halide (e.g. SiCl 4) is reacted with water, the orthosilicic acid (monosilicic acid), H 4 SiO 4, which separates off water permanently and intermolecularly only in great dilution, is formed primarily. The first condensation product is disilicic acid (pyrosilicic acid, H 6 Si 2 O 7). Further condensation leads via cyclic silicas and cage-like silicas to approximately spherical polysilicic acids. The final formal product of the condensation is polymeric silica, (SiO 2)x, the anhydride of the silica. During the condensation, chain-lengthening, ring-forming and branching processes proceed side by side, so that the polysilicic acids have a disordered structure (amorphous). In all silicas, the Si atoms are located at the midpoint of irregularly linked tetrahedrons, at whose 4 corner points O atoms are located, which simultaneously belong to the adjacent tetrahedrons.Silicas can be prepared from the solution ("Fällungskieselsäuren") or by pyrolysis of volatile Si compounds ("fumed silicas"). In terms of the production scope, precipitated silicas have by far the greatest significance. They are prepared from an aqueous alkali metal silicate solution by precipitation with mineral acids. Colloidal primary particles are formed, which agglomerate with the progress of the reaction and finally coalesce into aggregates. The powdery bulky shapes have pore volumes of 2.5-15 mL / g and specific surface areas of 30-800 m 2 / g.Fumed silicas are taken together as highly disperse silicas which are prepared by flame hydrolysis. In this process, silicon tetrachloride is decomposed in a oxyhydrogen flame. Fumed silicas have significantly fewer OH groups on their almost pore-free surface than precipitated silicas. The silica frequently undergoes chemical aftertreatment processes in which the OH groups react, for example, with organic chlorosilanes. This produces modified, for example hydrophobic, surfaces which substantially expand the performance properties of the silicas. In the context of the present invention, both precipitated and pyrogenic silicic acids can be used. Silicas which can preferably be used have specific surfaces of 25 to 1000 m 2 / g, oil numbers of 30 to 300 g / 100 g, primary particle sizes of 5 to 500 nm, densities of 1.9 to 2.2 g / cm 3 and drying loss < 7%, preferably<3%. Commercial products which can be used in the context of the present invention are sold, for example, under the trade names Aerosil ®, Cab-O-Sil ® and HDK.Agents preferred according to the invention are characterized in that they contain, based on the weight of the agent, 0.05 to 5 wt %, preferably 0.1 to 3 wt %, particularly preferably 0.15 to 2 wt %, and in particular 0.2 to 1 wt % of silica.In a preferred embodiment of the present invention, the colorants further comprise at least one fully or partially hydrogenated vegetable oil. Vegetable oils preferred according to the invention are, for example, soybean oil, coconut oil, hazelnut oil, palm kernel oil, sunflower oil, flaxseed oil, peanut oil, castor oil or rapeseed oil.A most preferred hydrogenated vegetable oil of the present invention is the hydrogenated castor oil sold under the trade name Cutina ® HR (Cognis).The compositions according to the invention comprise the completely or partially hydrogenated vegetable oils preferably in amounts of from 0.1 to 7% by weight, a range of from 0.4 to 1.2% by weight being particularly preferred.In a further preferred embodiment of the present invention, the colorants further comprise at least one non-ionic surfactant. Nonionic surfactants contain, as hydrophilic group, for example, a polyol group, a polyalkylene glycol ether group or a combination of polyol and polyglycol ether group. Such compounds are, for exampleaddition products of 2 to 30 mol of ethylene oxide and / or 0 to 5 mol of propylene oxide onto linear fatty alcohols having 8 to 22 carbon atoms, onto fatty acids having 12 to 22 carbon atoms and onto alkyl phenols having 8 to 15 carbon atoms in the alkyl group,C 12- C 22- fatty acid mono- and diesters of adducts of from 1 to 30 mol of ethylene oxide with glycerol,C 8- C 22- alkyl mono- and oligoglycosides and ethoxylated analogues thereof, andaddition products of 5 to 60 mol ethylene oxide with castor oil and hydrogenated castor oil.Preferred nonionic surfactants are alkyl polyglycosides of the general formula R 1 O-(Z) x. These compounds are characterized by the following parameters.The alkyl radical R 1 contains 6 to 22 carbon atoms and can be linear or branched. Primary linear aliphatic radicals which are methyl-branched in the 2-position are preferred. Examples of such alkyl radicals are 1-octyl, 1-decyl, 1-lauryl, 1-myristyl, 1-cetyl and 1-stearyl. Particular preference is given to 1-octyl, 1-decyl, 1-lauryl, 1-myristyl. When so-called "oxo alcohols" are used as starting materials, compounds having an odd number of carbon atoms in the alkyl chain are predominant.The alkyl polyglycosides which can be used according to the invention can, for example, comprise only one specific alkyl radical R 1. Usually, however, these compounds are prepared starting from natural fats and oils or mineral oils. In this case, alkyl radicals R present are mixtures corresponding to the starting compounds or corresponding to the respective workup of these compounds.Particularly preferred are those alkyl polyglycosides in which R 1essentially from C 8- and C 10- alkyl groups,essentially from C 12- and C 14- alkyl groups,essentially from C 8- to C 16- alkyl groups, oressentially consisting of C 12- to C 16- alkyl groups.As sugar building block Z, any mono- or oligosaccharides can be used. Sugars having 5 or 6 carbon atoms and the corresponding oligosaccharides are usually used. Such sugars are, for example, glucose, fructose, galactose, arabinose, ribose, xylose, lyxose, allose, altrose, mannose, gulose, idose, talose and sucrose. Preferred sugar building blocks are glucose, fructose, galactose, arabinose and sucrose; glucose is particularly preferred.The alkyl polyglycosides which can be used according to the invention contain on average 1.1 to 5 sugar units. Alkyl polyglycosides having x values of from 1.1 to 1.6 are preferred. Alkyl glycosides in which x is 1.1 to 1.4 are very particularly preferred.In addition to their surfactant action, the alkyl glycosides can also serve to improve the fixation of perfume components on the hair. The skilled worker will therefore, in the event that an effect of the perfume oil on the hair beyond the duration of the hair treatment is desired, preferably resort to this class of substances as a further ingredient of the preparations according to the invention.The alkoxylated homologues of the alkyl polyglycosides mentioned can also be used according to the invention. These homologues may contain on average up to 10 ethylene oxide and / or propylene oxide units per alkylglycoside unit.Non-ionic surfactants preferred according to the invention are the addition products of 2 to 30 mol ethylene oxide and / or 0 to 5 mol propylene oxide onto linear fatty alcohols having 8 to 22 carbon atoms. In the case of these surfactants, which are addition products of ethylene oxide and / or propylene oxide on fatty alcohols or derivatives of these addition products, it is possible to use both products having a "normal" homolog distribution and products having a narrowed homolog distribution. "Normal" homologue distribution is understood here to mean mixtures of homologues 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 are obtained, on the other hand, if hydrotalcites, alkaline earth metal salts of ethercarboxylic acids, alkaline earth metal oxides, hydroxides or alcoholates are used as catalysts, for example. The use of products with narrowed homolog distribution may be preferred. Can we incorporate a list of concrete compounds / commercial products?According to the invention, it has proven particularly preferable to use two different addition products of ethylene oxide to linear fatty alcohols.

Fatty substances are understood according to the invention to mean fatty acids, fatty alcohols, natural and synthetic waxes, which can be present both in solid form and liquid form in aqueous dispersion, and natural and synthetic cosmetic oil components.As fatty acids (D1), linear and / or branched, saturated and / or unsaturated fatty acids having 6-30 carbon atoms can be used. Fatty acids having 10-22 carbon atoms are preferred. These would include, for example, the isostearic acids, such as the commercial products Emersol ®871 and Emersol ®875, and isopalmitinic acids, such as the commercial product Edenor ® IP 95, and all other fatty acids sold under the trade names Edenor ®( Cognis).

The amount is preferably 0.5-10% by weight, it being possible with very particular advantage to use amounts of 1-5% by weight.As fatty alcohols (D2), it is possible to use saturated, mono- or polyunsaturated, branched or unbranched fatty alcohols having C 6- C 30-, preferably C 10- C 30- and very particularly preferably C 12- C 22- carbon atoms.

Ampholytic surfactants are understood to mean those surface-active compounds which, in addition to a C 8- C 18- alkyl or acyl group in the molecule, contain at least one free amino group and at least one -COOH- or -SO 3 H group and are capable of forming inner salts. Examples of suitable ampholytic surfactants are N-alkyl glycines, N-alkyl propionic acids, N-alkylamino butyric acids, N-alkylimino dipropionic acids, N-hydroxyethyl-N-alkyl amidopropyl glycines, N-alkyl taurines, N-alkyl sarcosines, 2-alkylamino propionic acids and alkylamino acetic acids each having about 8 to 18 C atoms in the alkyl group.

Preferred esterquats are quaternized ester salts of fatty acids with triethanolamine, quaternized ester salts of fatty acids with diethanol alkylamines and quaternized ester salts of fatty acids with 1,2-dihydroxypropyl dialkylamines. Such products are marketed, for example, under the trade names Stepantex ®, Dehyquart ® and Armocare ®.

However, it is generally preferred to start from 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 addition products of ethylene oxide and / or propylene oxide onto fatty alcohols or derivatives of these addition products, it is possible to use both products having a "normal" homolog distribution and products having a narrowed homolog distribution. "Normal" homologue distribution is understood here to mean mixtures of homologues 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 are obtained, on the other hand, if hydrotalcites, alkaline earth metal salts of ethercarboxylic acids, alkaline earth metal oxides, hydroxides or alcoholates are used as catalysts, for example. The use of products with narrowed homolog distribution may be preferred.However, it has proven particularly advantageous according to the invention if the colorants are formulated free of anionic, zwitterionic and / or ampholytic surfactants.Furthermore, the colorants according to the invention can comprise further active substances, auxiliaries and additives, for examplenonionic polymers such as, for example, vinylpyrrolidone / vinyl acrylate copolymers, polyvinylpyrrolidone and vinylpyrrolidone / vinyl acetate copolymers and polysiloxanes,cationic polymers such as quaternized cellulose ethers, polysiloxanes having quaternary groups, dimethyldiallylammonium chloride polymers, acrylamide-dimethyldiallylammonium chloride copolymers, dimethylaminoethyl methacrylate-vinylpyrrolidone copolymers quaternized with diethyl sulfate, vinylpyrrolidone-imidazolinium methochloride copolymers and quaternized polyvinyl alcohol,zwitterionic and amphoteric polymers such as, for example, acrylamidopropyltrimethylammonium chloride / acrylate copolymers and octylacrylamide / methyl methacrylate / tert-butylaminoethyl methacrylate / 2-hydroxypropyl methacrylate copolymers,anionic polymers such as polyacrylic acids, crosslinked polyacrylic acids, vinyl acetate / crotonic acid copolymers, vinyl pyrrolidone / vinyl acrylate copolymers, vinyl acetate / butyl maleate / isobornyl acrylate copolymers, methyl vinyl ether / maleic anhydride copolymers and acrylic acid / ethyl acrylate / N-tert-butyl acrylamide terpolymers,thickeners such as agar agar, guar gum, alginates, xanthan gum, gum arabic, karaya gum, locust bean gum, flaxseed gums, dextrans, cellulose derivatives, e.g. methylcellulose, hydroxyalkylcellulose and carboxymethylcellulose, starch fractions and derivatives such as amylose, amylopectin and dextrins, clays such as bentonite or fully synthetic hydrocolloids such as polyvinyl alcohol,structureants such as maleic acid and lactic acid,hair-conditioning compounds such as phospholipids, for example soybean lecithin, egg lecithin and cephalins,protein hydrolysates, in particular elastin, collagen, keratin, milk protein, soybean protein and wheat protein hydrolysates, their condensation products with fatty acids and quaternized protein hydrolysates,perfume oils, dimethyl isosorbide and cyclodextrins,fibre structure improving active ingredients, in particular mono-, di- and oligosaccharides such as, for example, glucose, galactose, fructose, fructose and lactose,quaternized amines such as methyl 1-alkylamidoethyl 2-alkylimidazolinium methosulfatedefoamers such as silicones,dyes for coloring the agent,anti-scale active substances such as piroctone olamine, zinc omadine and climbazole,light stabilizers, in particular derivatized benzophenones, cinnamic acid derivatives and triazines,substances for adjusting the pH, such as, for example, customary acids, in particular food acids and bases,active compounds such as allantoin, pyrrolidone carboxylic acids and their salts, and bisabolol,vitamins, provitamins and vitamin precursors, especially those of groups A, B 3, B 5, B 6, C, E, F and H,plant extracts such as the extracts from green tea, oak bark, stinging nettle, hamamelis, hop, chamomile, burdock root, horsetail, whitethorn, lime blossom, almond, aloe vera, spruce needle, rust kastania, sandalwood, juniper, coconut, mango, apricot, lime, wheat, kiwi, melon, orange, grapefruit, sage, rosemary, birch, maltve, meadow froth herb, quendel, sheep garbe, thyme, melissa, hauhechel, hooflattich, eggbean, Meristem, Ginseng and Ginger root.cholesterol,consistency regulators such as sugar esters, polyol esters or polyol alkyl ethers,fats and waxes such as walrate, bees wax, montan wax and paraffins,fatty acid alkanolamides,complex formers such as EDTA, NTA, β-alanine diacetic acid and phosphonic acids,swelling and penetration substances such as glycerol, propylene glycol monoethyl ether, carbonates, hydrogen carbonates, guanidines, ureas and primary, secondary and tertiary phosphates,Opacifiers such as latex, styrene / PVP and styrene / acrylamide copolymerspearlescent agents such as ethylene glycol mono- and distearate and PEG-3-distearate,pigments,stabilizing agents for hydrogen peroxide and other oxidizing agents,propellants such as propane-butane mixtures, N 2 O, dimethyl ether, CO 2 and air,antioxidants,These are also particularly preferred.With regard to further optional components and the amounts of these components used, reference is expressly made to the relevant handbooks known to the skilled worker, for example Kh. Schrader, Grundlagen und Rezepturen der Kosmetika, 2nd Edition, Huthig Buch Verlag, Heidelberg, 1989.The present invention also provides two-component compositions for dyeing keratin fibers, which comprise a first preparation comprising (A) at least one dye precursor and / or one direct dye (B) at least one fatty acid glyceryl ester and (C) at least one cationic surfactant of the formula (I) where the radicals R 1 to R 4 independently of one another are a C 1- to C 4- alkyl chain or a C 10- to C 30- alkyl chain, with the proviso, wherein at least one and at most two of the radicals R 1 to R 4 are a C 12- to C 30- alkyl chain, and X is a physiologically tolerable anion, and (D) ammonium bicarbonate, and a second preparation comprising at least one oxidizing agent.In a preferred embodiment of this subject matter according to the invention, the second preparation contains at least one anionic or at least one cationic surfactant. With regard to the anionic or cationic surfactants preferred according to the invention, reference is made at this point to the above explanations. The colorants of this embodiment according to the invention are distinguished by an excellent viscosity of the resulting application preparation. The viscosity is such that the compositions can be well distributed on the hair without subsequently dripping off.The two-component compositions according to the invention are distinguished by good miscibility, ease of manufacture and outstanding long-term stability.If the formation of the actual coloring takes place in the context of an oxidative process, conventional oxidizing agents such as, in particular, hydrogen peroxide or its addition products with urea, melamine or sodium borate can be used. However, oxidation with atmospheric oxygen as the sole oxidizing agent may be preferred. However, a chemical oxidizing agent is preferably used, especially if, in addition to coloring, a lightening effect on human hair is desired. Suitable oxidizing agents are persulfates, chlorites and, in particular, hydrogen peroxide or its addition products with urea, melamine and sodium borate. According to the invention, however, the oxidation dye can also be applied to the hair together with a catalyst which activates the oxidation of the dye precursors, for example by atmospheric oxygen. Such catalysts are, for example, metal ions, iodides, quinones or certain enzymes.Suitable metal ions are, for example, Zn 2+, Cu 2+, Fe 2+, Fe 3+, Mn 2+, M n4+, Li +, Mg 2+, Ca 2+ and Al 3+. Particularly suitable in this case are Zn 2+, Cu 2+ and Mn 2+. The metal ions can in principle be used in the form of any desired physiologically tolerable 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 coloration can be accelerated and the color nuance can be specifically influenced.Suitable enzymes are, for example, peroxidases which can clearly enhance the effect of small amounts of hydrogen peroxide. Enzymes which are suitable according to the invention are furthermore those which directly oxidize the oxidation dye precursors, such as the laccases, with the aid of atmospheric oxygen or generate small amounts of hydrogen peroxide in situ and in this way 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 substrates specific therefor, for example.pyranose oxidase and, for example, D-glucose or galactose,glucose oxidase and D-glucose,glycerol oxidase and glycerol,pyruvate oxidase and pyruvic acid or salts thereof,alcohol oxidase and alcohol (MeOH, EtOH),lactate oxidase and lactic acid and salts thereof,tyrosinase oxidase and tyrosine,uricase and uric acid or salts thereof,choline oxidase and choline,amino acid oxidase and amino acids.The actual oxidative coloring agent is expediently produced immediately before use by mixing the preparation of the oxidizing agent with the preparation containing the dye precursors. The ready-to-use hair dye preparation formed should preferably have a pH in the range from 5 to 14, in particular from 7 to 12. Particular preference is given to the use of the hair colorants in a weakly alkaline medium. The application temperatures can be in a range between 15 and 40° C. After a contact time of 5 to 45 minutes, the hair dye is removed from the hair to be dyed by rinsing. Afterwashing with a shampoo is dispensed with if a carrier containing a high surfactant content, for example a dyeing shampoo, has been used.In particular in the case of hair which is difficult to dye, the preparation comprising the dye precursors can, however, also 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, optionally after an intermediate rinsing. After a further exposure time of 10 to 20 minutes, rinsing is then carried out and, if desired, after-shampooed. In this embodiment, according to a first variant, in which the prior application of the dye precursors is intended to bring about 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 first sought, wherein the applied agent preferably has a pH of 7 to 10.
