Description

"Brightening and / or coloring agents with oxalic acid compounds"

The present invention relates to means for dyeing and / or whitening keratinic fibers, i. Agent for use on keratin fibers, in particular human hair, and their use.

The change in shape and color of the hair is an important area of modern cosmetics dar. Thus, the appearance of the hair can be adapted to both current fashion trends and the individual desires of each person. In this case, permanent wave and other hair-changing methods can be used almost independently of the type of hair to be treated. In contrast, dyeing and bleaching processes are limited to certain initial hair colors. The basics of the bleaching processes are known to those skilled in the art and may be described in relevant monographs, e.g. by Kh. Schrader, Basics and Formulations of Cosmetics, 2nd edition, 1989, Dr. med. Alfred Hüthig Verlag, Heidelberg, or W. Limbach (ed.), Cosmetics, 2nd edition, 1995, Georg Thieme Verlag, Stuttgart, New York, be read.

At the same time, however, there is often the desire to change the hair color and to achieve a brightening of the hair to be dyed together with the hair coloring.

Conventional hair dyes usually consist of at least one developer and at least one coupler substance and possibly even contain direct dyes as Nuanceure. Coupler and developer components are also referred to as oxidation dye precursors. Before being applied to human hair, hair dyeing and / or whitening agents are mixed in solid or pasty form with dilute aqueous hydrogen peroxide solution. This mixture is then applied to the hair and rinsed again after a certain exposure time. The duration of exposure to the hair to achieve complete coloration or lightening is between about 30 and 40 minutes. It is obvious that there is a need among users of these hair dyes or bleaching agents to reduce this exposure time.

Neither the pasty nor the powdered dyeing and / or bleaching agents that are on the market today can be considered optimal. While the dyeing and / or bleaching effect on the hair may be said to be tailored to consumer needs, there are still a number of disadvantages and problems both in the manufacture and handling of these agents.

Thus, coloration and bleaching processes on keratinic fibers usually proceed at alkaline pH values, in particular between 9.0 and 10.5. These pH values are necessary to ensure an opening of the outer cuticle (cuticle) and to allow a penetration of the active species (dye precursors and / or hydrogen peroxide) into the hair. The alkalizing agent used is usually ammonia, which however has the disadvantage of intense odor and possible irritation for the users.

In market products, for example, aminomethylpropanol or monoethanolamine are used as alternative alkalizing agents to ammonia. However, since they often lag behind ammonia in their performance, they are usually used in admixture with ammonia. But even here, the performance of the ammonia is impaired, especially with regard to the parameters gray covering, whitening performance and color result.

There is therefore still a need for active ingredients or active substance combinations for brightening and coloring agents with reduced ammonia content. In particular, in ammonia-reduced or even-free dye and / or hydrogen peroxide-containing Formulations can be achieved comparable performance with conventional ammonia-based agents.

It has now been found that azole derivatives of oxalic acid and / or oxalic acid can be incorporated with particular advantage into hair dyeing and lightening agents and lead to an increase in the performance of these agents.

The present invention, in a first embodiment, means for dyeing and / or lightening Keratinfasem, in particular human hair, containing - based on its weight - 0.001 to 15 wt .-% of one or more compounds of oxalic acid from the groups of

Under Keratinfasem are to understand fur, wool, feathers and especially human hair. Although the compositions according to the invention are primarily suitable for dyeing and / or whitening keratin fibers, in principle there is nothing to prevent their use in other fields as well.

The compositions of the invention contain as essential ingredient at least one ester and / or at least one amide of oxalic acid and / or of derivatives of oxalic acid, in which one or two (C = O) groups are replaced by (C = NR ¹ ) groups. Depending on the further substitution pattern, these derivatives are used as ethanediimidic acid esters (substitution of both (C =O) groups with two series of esters, the mono- and diesters) or as Hydroxyiminoessigsäureester (substitution of a (C = O) group, an ester function at C Atom carrying the (C = O) group), or as Alkoxyiminoacetic acid (substitution of a (C = O) group, an "ester" function on the C atom bearing the (C = NR ¹ ) group), or as an alkoxyimioacetic acid ester (substitution of a (C = O) group, two Ester functions at the C atom bearing the (C = O) group and at the C atom bearing the (C = NR ¹ ) group).

The oxalic acid forms, in addition to the mono- and diesters, also the orthophosphoric acid analogous orthoacetic acid esters of which there are two series, since the oxalic acid has two -C (O) groups.

Furthermore, it has proved to be advantageous if the dyeing and / or brightening agents according to the invention contain nonionic surfactants. Such surfactants having an HLB of 5.0 and greater are preferred. For the definition of the HLB value, explicit reference is made to the statements in Hugo Janistyn, Handbuch der Kosmetika und Riechstoffe, III. Volume: The personal care products, 2nd edition, Dr. med. Alfred Hüthig Verlag Heidelberg, 1973, pages 68-78 and Hugo Janistyn, Paperback of modern perfumery and cosmetics, 4th edition, Scientific Publishing Company m.b.H. Stuttgart, 1974, pages 466-474, as well as the original works cited therein.

Particularly preferred non-ionic surface-active substances are substances that are commercially available as solids or liquids in pure form because of their ease of processing. The definition of purity in this context does not refer to chemically pure compounds. Rather, especially when it comes to products based on natural substances, mixtures various homologs are used, for example, with different alkyl chain lengths, as obtained in products based on natural fats and oils. Even with alkoxylated products, mixtures of different degrees of alkoxylation are usually present. The term purity in this context refers rather to the fact that the chosen substances should preferably be free from solvents, stabilizers and other impurities.

Preferred nonionic surfactants are

- Alkoxylated fatty alcohols having 8 to 22, in particular 10 to 16, carbon atoms in the fatty alkyl group and 1 to 30, in particular 1 to 15, ethylene oxide and / or propylene oxide units. Preferred fatty alkyl groups are, for example, lauryl, myristyl, cetyl, but also stearyl, isostearyl and oleyl groups. Particularly preferred compounds of this class are, for example, lauryl alcohol with 2 to 4 ethylene oxide units, oleyl and cetyl alcohol with 5 to 10 ethylene oxide, cetyl alcohol and stearyl alcohol and mixtures thereof with 10 to 30 ethylene oxide units and the commercial product Aethoxal ^® B (Henkel), a Lauryl alcohol with 5 ethylene oxide and 3 propylene oxide units. In addition to the usual alkoxylated fatty alcohols, it is also possible to use so-called "end-capped" compounds according to the invention In these compounds, the alkoxy group has no OH group at the end but is "closed" in the form of an ether, in particular a C 1 -C 4 -alkyl ether. , An example of such a compound is the commercially available product ^® Dehypon LT 054, a C _{2- 8} -Fettalkoholol i + 4.5 ethylene oxide-butyl ether.

- alkoxylated fatty acids having 8 to 22, in particular 10 to 16, carbon atoms in the fatty acid group and 1 to 30, in particular 1 to 15, ethylene oxide and / or propylene oxide units. Preferred fatty acids are, for example, lauric, myristic, palmitic, stearic, isostearic and oleic acids.

- alkoxylated, preferably propoxylated and especially ethoxylated, mono-, di- and triglycerides. Examples of preferred compounds are glycerol monolaurate + 20 ethylene oxide and glycerol monostearate + 20 ethylene oxide. Polyglycerol esters and alkoxylated polyglycerol esters. Preferred compounds of this class are for example poly (3) glycerol diisostearate (commercial product: Lameform ^® TGI (Henkel)) and poly (2) glycerinpolyhydroxy- stearate (commercial product: Dehymuls ^® PGPH (Henkel)).

Sorbitan fatty acid esters and alkoxylated sorbitan fatty acid esters such as sorbitan monolaurate and sorbitan monolaurate + 20 ethylene oxide (EO).

- Alkylphenols and Alkylphenolalkoxylate having 6 to 21, in particular 6 to 15, carbon atoms in the alkyl chain and 0 to 30 ethylene oxide and / or propylene oxide units. Preferred representatives of this class are, for example, nonylphenol + 4 EO, nonylphenol + 9 EO ₁ octylphenol + 3 EO and octylphenol + 8 EO.

Particularly preferred classes of nonionic surfactants are the alkoxylated fatty alcohols, the alkoxylated fatty acids and the alkylphenols and alkylphenol alkoxylates.

Agents according to the invention which contain non-ionic surface-active substances in amounts of 1 to 5% by weight have proved to be particularly advantageous.

Furthermore, the dyeing and / or brightening agents according to the invention may contain all known in such preparations active ingredients, additives and excipients. In many cases, the agents contain at least one surfactant, wherein in principle both anionic and zwitterionic, ampholytic, nonionic and cationic surfactants are suitable. In many cases, however, it has proved to be advantageous to select the surfactants from anionic, cationic or nonionic surfactants. Anionic surfactants may be very particularly preferred.

Preferred anionic surfactants are alkyl sulfates, ether carboxylic acid salts having 10 to 18 carbon atoms in the alkyl group and up to 12 glycol ether groups in the molecule such as Ci ₂ H ₂ S- (C ₂ H ₄ O) ₆ -CH ₂ -COONa and in particular salts of saturated and especially unsaturated C8-C22 carboxylic acids such as oleic acid, stearic acid, isostearic acid and palmitic acid. These anionic surfactants should preferably be present in solid, in particular powder form. Very particular preference is given to solid soaps, especially sodium stearate, at room temperature. These are preferably present in amounts of from 5 to 20% by weight, in particular from 10 to 15% by weight.

Particularly suitable nonionic surfactants are C8-C22-alkyl mono- and oligoglycosides and their ethoxylated analogs. In particular, the nonethoxylated compounds have been found to be particularly suitable.

Examples of the cationic surfactants which can be used in the hair treatment compositions according to the invention are, in particular, quaternary ammonium compounds. Preference is given to ammonium halides such as alkyltrimethylammonium chlorides, dialkyldimethylammonium chlorides and trialkylmethylammonium chlorides, eg. For example, cetyltrimethylammonium chloride, stearyltrimethylammonium chloride, distearyldimethylammonium chloride, lauryldimethylammonium chloride, lauryldimethylbenzylammonium chloride and tricetylmethylammonium chloride. Further cationic surfactants which can be used according to the invention are the quaternized protein hydrolysates.

Alkylamidoamines, in particular fatty acid amidoamines, such as the ^{stearylamidopropyldimethylamine} obtainable under the name Tego ^Amid® S 18, are distinguished not only by a good conditioning action but also by their good biodegradability.

Also very good biodegradability are quaternary Esterverbindungen, so-called "esterquats", such as the Distearoylethylhydroxyethylammoniummethosulfat available in a blend with Cetearylalkohle under the name Dehyquart® ^® F 75 miles.

The compounds containing alkyl groups used as surfactants may each be uniform substances. However, it is usually preferred to start from the production of these substances from native plant or animal raw materials, so as to obtain substance mixtures with different, depending on the particular raw material alkyl chain lengths. As a further constituent, the compositions according to the invention may comprise at least one ammonium compound from the group consisting of ammonium chloride, ammonium carbonate, ammonium bicarbonate, ammonium sulfate and / or

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.

The compositions according to the invention may contain the ingredients in a suitable aqueous, alcoholic or aqueous-alcoholic carrier. For the purpose of hair coloring such carriers are, for example, creams, emulsions, gels or surfactant-containing foaming solutions, such as shampoos, foam aerosols or other preparations which are suitable for use on the hair. But it is also possible to provide a powdered or tablet-shaped formulation, which is preferred for dyeing and / or brightening agents.

For the purposes of the present invention, aqueous-alcoholic solutions are to be understood as meaning aqueous solutions containing from 3 to 70% by weight of a C 1 -C ₄ -alcohol, in particular ethanol or isopropanol. The compositions of the invention may additionally contain other organic solvents, such as methoxybutanol, benzyl alcohol, ethyl diglycol or 1, 2-propylene glycol. Preference is given to all water-soluble organic solvents.

Preferred agents according to the invention are characterized in that they additionally contain a non-aqueous solvent, with particularly preferred compositions according to the invention the solvent in a concentration of 0.1 to 30 weight percent, preferably in a concentration of 1 to 20 weight percent, most preferably in a concentration of 2 to 10 weight percent, each based on the agent.

In further preferred agents according to the invention, the solvent is selected from ethanol, n-propanol, isoropanol, n-butanol, propylene glycol, n-butylene glycol, glycerol, Diethylene glycol monoethyl ether, diethylene glycol mono-n-butyl ether, phenoxyethanol and benzyl alcohol and their mixtures.

The pH of the compositions according to the invention can be adjusted within a wide range by suitable ingredients such as acidifying agent or alkalizing agent.

Oxidative dyeing of the fibers can in principle be carried out with atmospheric oxygen in the presence of oxidation dye precursors. Preferably, however, a chemical oxidizing agent is used, especially if, in addition to the coloring, a lightening effect on human hair is desired. This lightening effect may be desired regardless of the staining method. The presence of oxidation dye precursors is therefore not a mandatory requirement for the use of oxidizing agents in the compositions of the invention. Suitable oxidizing agents are persulfates, chlorites and in particular hydrogen peroxide or its addition products of urea, melamine and sodium borate.

However, according to the invention, the oxidation colorant can also be applied to the hair together with a catalyst which promotes the oxidation of the dye precursors, e.g. by atmospheric oxygen, activated. Such catalysts are e.g. Metal ions, iodides, quinones or certain enzymes.

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 include peroxidases, which can significantly enhance the effect of small amounts of hydrogen peroxide. Furthermore, such enzymes are suitable according to the invention which directly oxidize the oxidation dye precursors with the aid of atmospheric oxygen, such as, for example, the laccases, or generate small amounts of hydrogen peroxide 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, for example pyranose oxidase and, for example, 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.

In an application of oxidants, the actual colorant is conveniently prepared immediately prior to use by mixing the preparation of the oxidizing agent with the preparation containing the compounds of formula I and optionally dye precursors. The resulting ready-to-use hair dye preparation should preferably have a pH in the range of 6 to 12. Particularly preferred is the use of the hair dye in a weakly alkaline medium. The application temperatures can be in a range between 15 and 40 ⁰ C. After a contact time of 5 to 45 minutes, the hair dye is removed by rinsing of the hair to be dyed. The washing with a shampoo is omitted if a strong surfactant-containing carrier, such as a dyeing shampoo was used.

In particular, in the case of hair that is difficult to dye, an agent according to the invention may optionally be applied to the hair with additional dye precursors but also without prior mixing with the oxidation component. After an exposure time of 20 to 30 minutes, the oxidation component is then applied, if appropriate after an intermediate rinse. After another The reaction time of 10 to 20 minutes is then rinsed and, if desired, post-sonicated. In this embodiment, according to a first variant, in which the previous application of the dye precursors is intended to effect a better penetration into the hair, the corresponding agent is adjusted to a pH of about 4 to 7. According to a second variant, an air oxidation is initially desired, wherein the applied agent preferably has a pH of 7 to 10. In the subsequent accelerated post-oxidation, the use of acidified peroxydisulfate solutions may be preferred as the oxidizing agent.

For the application of the compositions of the invention on the hair dyeing and / or brightening agents are mixed immediately before application with a hydrogen peroxide solution. The concentration of this hydrogen peroxide solution is determined on the one hand by the legal requirements and on the other hand by the desired effect; As a rule, 6-12% solutions in water are used. The proportions of dyeing and / or lightening agent and hydrogen peroxide solution are usually in the range 1: 1 to 1: 2, with an excess of hydrogen peroxide solution is particularly selected when no too pronounced Blondierwirkung is desired.

In addition, the compositions according to the invention may contain further ingredients. For example, use of certain metal ions or complexes may be preferred to obtain intense colorations. Agents according to the invention which additionally contain Cu, Fe, Mn, Ru ions or complexes of these ions are preferred here.

Preferred agents according to the invention for dyeing and / or lightening keratinic fibers additionally contain Cu, Fe, Mn, Co, Ce, V, Ru ions or complexes of these ions, preferred agents being from 0.0001 to 2.5% by weight .-%, preferably 0.001 to 1% by weight of at least one compound from the group copper chloride (CuCl ₂ ), copper sulfate (CuSO ₄ ), iron (II) sulfate, manganese (II) sulfate, manganese (II) chloride, cobalt ( ll) chloride, cerium sulfate, cerium chloride, vanadium sulfate, manganese dioxide (MnO ₂ ).

Also preferred according to the invention is the use of so-called complexing agents. Complex images are substances that can complex metal ions. Preferred complexing agents are so-called chelate complexing agents, ie substances that react with metal ions form cyclic compounds, wherein a single ligand occupies more than one coordination site on a central atom, ie mind. "Bidentate" is. In this case, normally stretched compounds are closed by complex formation via an ion into rings. The number of bound ligands depends on the coordination number of the central ion.

Customary and preferred chelate complex images in the context of the present invention are, for example, polyoxycarboxylic acids, polyamines, ethylenediaminetetraacetic acid (EDTA), nitrilotriacetic acid (NTA) and hydroxyethanediphosphonic acids or their alkali metal salts. Also, complex-forming polymers, ie polymers which carry functional groups either in the main chain itself or laterally to it, which can act as ligands and react with suitable metal atoms usually with the formation of chelate complexes, can be used according to the invention. The polymer-bound ligands of the resulting metal complexes can originate from only one macromolecule or belong to different polymer chains. The latter leads to the crosslinking of the material, provided that the complex-forming polymers were not previously crosslinked via covalent bonds.

Complexing groups (ligands) of conventional complex-forming polymers are iminodiacetic acid, hydroxyquinoline, thiourea, guanidine, dithiocarbamate, hydroxamic acid, amidoxime, aminophosphoric acid, (cyclic) polyamino, mercapto, 1,3-dicarbonyl - And crown ether residues with z. T. very specific. Activities towards ions of different metals. Base polymers of many also commercially important complex-forming polymers are polystyrene, polyacrylates, polyacrylonitriles, polyvinyl alcohols, polyvinylpyridines and polyethyleneimines. Natural polymers such as cellulose, starch or chitin are also complex-forming polymers. In addition, these can be provided by polymer-analogous transformations with other ligand functionalities.

In the context of the present invention, it is particularly preferable to use one or more chelating agents from the groups of

(i) polycarboxylic acids in which the sum of the carboxyl and optionally hydroxyl groups is at least 5, (ii) nitrogen-containing mono- or polycarboxylic acids,

(iii) geminal diphosphonic acids,

(iv) aminophosphonic acids,

For the purposes of this patent application, polycarboxylic acids a) are understood as meaning carboxylic acids, including monocarboxylic acids, in which the sum of carboxyl groups and the hydroxyl groups contained in the molecule is at least 5. Complexing agents from the group of nitrogen-containing polycarboxylic acids, in particular EDTA, are preferred. At the alkaline pH values of the treatment solutions required according to the invention, These complexing agents are at least partially present as anions. It is irrelevant whether they are introduced in the form of acids or in the form of salts.

- If desired, a pretreatment agent M1 is applied to the fiber, then

a means M2 is applied to the fiber, optionally adding a further agent M3 to the agent M2 before use, rinsing off this agent M2 from the fiber after a period of 5-30 minutes and, if desired, a post-treatment agent M4 after the treatment is applied to the fiber and rinsed off after a contact time of a few minutes, wherein at least one of the means M1, M2 or M3 is an inventive agent. The agents according to the invention can accordingly be formulated as single-component agents (dyeing and whitening agents M2 or aftertreatment agents M4), as two-component agents (M2 + M3) or as three-component agents (M2 + M3 + M4) and used accordingly. Separation into multicomponent systems is particularly suitable where incompatibilities of the ingredients are to be expected or feared; the agent to be used in such systems is manufactured by the consumer just prior to use by mixing the component.

A dyeing and whitening process in which the whitening cream and the oxidizing agent are initially separate is preferred. A further subject of the present invention is therefore a process for dyeing and lightening human hair, in which an aqueous-based composition containing hydrogen peroxide is mixed with an agent according to the invention to form a homogeneous composition and applied to the hair.
