Description

 "Use of indanones for dyeing keratin fibers"

The invention relates to the use of indanones for dyeing keratin-containing fibers, in particular human hair, an agent for dyeing keratin-containing fibers, which contains indanones, and a method for dyeing keratin-containing fibers.

For dyeing keratin fibers, e.g. B. hair, wool or fur, generally either direct dyes or oxidation dyes, which are formed by oxidative coupling of one or more developer components with one another or with one or more coupler components, are used. Coupler and developer components are also referred to as oxidation color dead precursors.

Primary aromatic amines with a further free or substituted hydroxy or amino group in the para or ortho position, diaminopyridine derivatives, heterocyclic hydrazones, 4-aminopyrazolone derivatives and 2,4,5,6-tetraaminopyrimidine and their derivatives are usually used as developer components.

Specific representatives are, for example, p-phenylenediamine, p-toluenediamine, 2,4,5,6-tetraaminopyrimidine, p-aminophenol, N, N-bis (2-hydroxyethyl) -p-phenylenediamine, 2- (2,5-diaminophenyl ) -ethanol, 2- (2,5-diaminophenoxy) -ethanol, 1 -phenyl-3-car-boxyamido-4-amino-pyrazolon-5, 4-amino-3-methylphenol, 2-aminomethyl-4-aminophenol, 2-hydroxymethyl-4-aminophenol, 2-hydroxy-4,5,6-triaminopyrimidine, 2,4-dihydroxy-5,6-diaminopyrimidine and 2,5,6-triamino-4-hydroxypyrimidine.

M-Phenylenediamine derivatives, naphthols, resorcinol and resorcinol derivatives, pyrazolones and m-aminophenols are generally used as coupler components. Suitable coupler substances are, in particular, α-naphthol, 1,5-, 2,7- and 1,7-dihydroxynaphthalene, 5-amino-2-methylphenol, m-aminophenol, resorcinol, resor- cinmonomethyl ether, m-phenylenediamine, 2,4-diaminophenoxyethanol, 1-phenyl-3-methyl-pyrazolon-5, 2,4-dichloro-3-aminophenol, 1,3-bis- (2,4-diaminophenoxy) propane, 2-chlororesorcinol, 4-chlororesorcinol, 2-chloro-6-methyl-3-aminophenol, 2-methylresorcinol and 5-methylresorcinol.

With regard to other conventional dye components, reference is expressly made to the “Dermatology” series, edited by Ch. Culnan, H. Maibach, Verlag Marcel Dekker Inc., New York, Basel, 1986, Vol. 7, Ch. Zviak, The Science of Hair Care, Chapter 7, pages 248 - 250 (direct dyes), and Chapter 8, pages 264 - 267 (oxidation dyes), as well as the "European inventory of cosmetic raw materials", 1996, published by the European Commission, available in disk form from the Federal Association of German Industrial and commercial companies for pharmaceuticals, health products and body care products eV, Mannheim.

Intensive dyeings with good fastness properties can be achieved with oxidation dyes, but the development of the color generally takes place under the influence of oxidizing agents such as H ₂ O ₂ , which in some cases can damage the fibers. Furthermore, some oxidation dye products or certain mixtures of oxidation dye precursors can sometimes have a sensitizing effect on people with sensitive skin. Direct dyes are applied under gentler conditions, but their disadvantage is that the dyeings often have inadequate fastness properties.

The published patent application DE 43 17 855 A1 discloses ninhydrin-containing agents for dyeing keratin-containing fibers. Ninhydrin or its derivatives can be used in combination with compounds containing amino groups, with heterocycles or with hydroxy-substituted aromatic compounds. From the published patent application DE 43 35 627 A1, 1,3-propanediones and their derivatives for dyeing keratin fibers are known, which can also be used in combination with amines and amino acids. However, the agents described in the above publications do not always result in colorations with the desired application properties. The object of the present invention is to provide colorants for keratin fibers, in particular human hair, which are qualitatively at least equivalent in terms of color depth, gray coverage and fastness properties to conventional oxidation hair colorants, but without being dependent on oxidizing agents such as H ₂ O ₂ . Another object of the present invention is to provide colorants with which a wide variety of color shades can be obtained. Staining of the skin areas should be avoided if possible. In addition, the colorants may have no or only a very low sensitization potential.

Surprisingly, it was found that combinations of indanones, as defined below, and amines, hydroxy compounds or CH-active compounds are outstandingly suitable for dyeing fibers containing keratin. They result in colors with excellent brilliance and depth of color and lead to a wide range of shades. The use of oxidizing agents is not necessary, but should not be excluded in principle.

The present invention accordingly relates to the use of indanones of the following formula I.

wherein R ¹ and R ² each independently represent a hydrogen atom, a halogen atom, a (CC ₄ ) alkyl group, (CC ₄ ) alkoxy group, hydroxy (C _r C ₄ ) alkoxy group, hydroxy group, nitro group, carboxy group, sulfo group, amino group , which can be substituted by (C, -C ₄ ) alkyl groups, or (C, - C ₄ ) acyl group, where the radicals R ¹ and R ² together can form a fused-on benzene ring, X is a nitromethylene group, an isonitrosomethylene group or one

Mean carbonyl group and

Y represents a methylene group, ethylene group or carbonyl group, with the proviso that X and Y are not simultaneously a carbonyl group, in the presence of at least one compound having a primary or secondary amino group or hydroxyl group selected from primary or secondary aliphatic or aromatic amines, nitrogen-containing heterocyclic compounds, α- to ω- amino acids, oligopeptides and aromatic hydroxy compounds composed of 2 to 9 amino acids, and / or at least one CH-active compound for dyeing fibers containing keratin.

Keratin-containing fibers are wool, furs, feathers and in particular human hair. In principle, however, the colorants according to the invention can also be used to dye other natural fibers, such as Cotton, jute, sisal, linen or silk, modified natural fibers, e.g. Regenerated cellulose, nitro, alkyl or hydroxyalkyl or acetyl cellulose and synthetic fibers such as e.g. Polyamide, polyacrylonitrile, polyurethane and polyester fibers can be used.

The presence of oxidizing agents, for example H ₂ O ₂ , can be dispensed with when using the indanones of the formula I according to the invention. However, it may be desirable to add hydrogen peroxide or other oxidizing agents to the agents according to the invention to obtain shades lighter than the keratin-containing fiber to be colored. Oxidizing agents are generally used in an amount of 0.01 to 6% by weight, based on the application solution. A preferred oxidizing agent for human hair is H ₂ O ₂ .

The colorants according to the invention result in a wide range of color shades in the range from yellow to yellow-brown, orange, brown-orange, medium brown, dark brown, violet, dark violet to blue-black and black; the fastness properties are excellent, the sensitization potential is very low. In a preferred embodiment, the colorants according to the invention contain, in addition to the compounds contained according to the invention, customary direct dyes, for example from the group of the nitrophenylenediamines, nitroaminophenols, anthraquinones or indophenols, such as those under the international names or trade names HC Yellow, for further modification of the shades 2, HC Yellow 4, HC Yellow 6, Basic Yellow 57, Disperse Orange 3, HC Red 3, HC Red BN, Basic Red 76, HC Blue 2, 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 picramic acid, 2-amino-6-chloro-4-nitrophenol, 4-amino-2-nitrodiphenylamine-2'-carboxylic acid, 6-nitro-1 , 2,3,4-tetrahydroquinoxaline, 4-N-ethyl-1,4-bis (2'-hydroxyethylamino) -2-nitrobenzene hydrochloride and 1-methyl-3-nitro-4- (2'-hydroxyethyl) - aminobenzene.

It is not necessary that the oxidation dye orproducts or the optional direct dyes each represent uniform compounds. Rather, in the colorants according to the invention, due to the production processes for the individual dyes, further components may also be present in minor amounts, provided that these do not adversely affect the coloring result or for other reasons, e.g. toxicological, must be excluded.

The colorants according to the invention produce intensive colorations even at physiologically tolerable temperatures of below 45 ° C. They are therefore particularly suitable for dyeing human hair. For use on human hair, the colorants can usually be incorporated into a water-containing cosmetic carrier. Suitable water-containing cosmetic carriers are, for example, creams, emulsions, gels or also surfactant-containing foaming solutions such as shampoos or other preparations which are suitable for use on the keratin-containing fibers. If necessary, it is also possible to incorporate the colorants into anhydrous carriers. Furthermore, the colorants according to the invention can contain all active substances, additives and auxiliaries known in such preparations. In many cases, the colorants contain at least one surfactant, both anionic and zwitterionic, ampholytic, nonionic and cationic surfactants being suitable in principle. In many cases, however, it has proven advantageous to select the surfactants from anionic, zwitterionic or nonionic surfactants.

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

In the case of the surfactants, which are addition products of ethylene and / or propylene oxide onto fatty alcohols or derivatives of these addition products, both products with a "normal" homolog distribution and those with a narrowed homolog distribution can be used. “Normal” homolog distribution is understood to mean mixtures of homologs which are obtained as catalysts from the reaction of fatty alcohol and alkylene oxide using alkali metals, alkali metal hydroxides or alkali metal alcoholates. In contrast, narrow homolog distributions are obtained if, 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 a narrow homolog distribution can be preferred.

The constituents of the water-containing carrier are used to produce the colorants according to the invention in amounts customary for this purpose; e.g. emulsifiers are used in concentrations of 0.5 to 30% by weight and thickeners in concentrations of 0.1 to 25% by weight of the total colorant.

For the coloring result it can be advantageous to add ammonium or metal salts to the coloring agents. Suitable metal salts are, for example, formates, carbonates, halides, sulfates, butyrates, valerates, capronates, acetates, lactates, glycolates, tartrates, citrates, gluconates, propionates, phosphates and phosphonates of alkali metals, such as potassium, sodium or lithium, alkaline earth metals, such as magnesium, Caicium, strontium or barium, or of aluminum, manganese, iron, cobalt, copper or zinc, with sodium acetate, lithium bromide, calcium bromide, calcium gluconate, zinc chloride, zinc sulfate, magnesium chloride, magnesium sulfate, ammonium carbonate, chloride and acetate being preferred. These salts are preferably present in an amount of 0.03 to 65, in particular 1 to 40 mmol, based on 100 g of the total colorant. The pH of the ready-to-use coloring preparations is usually between 2 and 11, preferably between 5 and 9.

For dyeing the keratin-containing fibers, in particular for dyeing human hair, the colorants are generally applied to the hair in the form of the water-containing, cosmetic carrier in an amount of 100 g, left there for about 30 minutes and then rinsed out or with a commercially available one Washed out hair shampoo.

The compounds of components A and B can either be applied to the hair simultaneously or in succession, it being irrelevant which of the components is applied first. The optionally contained ammonium or metal salts can be added to the first or the second component. There may be an interval of up to 30 minutes between the application of the first and the second component. Pretreatment of the fibers with the saline solution is also possible.

Components A and B of the agents according to the invention can either be stored separately or together, either in a liquid to pasty preparation (aqueous or anhydrous) or as a dry powder. If the components are stored together in a liquid preparation, this should be largely anhydrous to reduce a reaction of the components. When stored separately, the reactive components are only intimately mixed with one another immediately before use. In dry storage, a defined amount of warm (50 to 80 ° C) water is usually added before use and a homogeneous mixture is produced.

Examples

Preparation of a coloring solution

A slurry of 10 mmoles of component A, 10 mmoles of an amine, 10 mmoles of sodium acetate and a drop of a 20% fatty alkyl ether sulfate solution in 100 ml of water was prepared. The slurry was briefly heated to about 80 ° C and filtered after cooling, the pH was then adjusted to 6.

A strand of 90% gray, untreated human hair was placed in this coloring solution at 30 ° C. for 30 minutes. The colored streak was then rinsed for 30 seconds with lukewarm water, dried in a warm (30-40 ° C.) air stream and then combed out. The colorations were then assessed visually in daylight.

The respective color shades and color depths are shown in the following table.

The color depth was rated on the following scale:
