Description

"Agents for coloring human hair" The invention relates to agents for permanent coloring of human hair using oxidation dyes based on polyfunctional benzene derivatives with 4 - 6 substituents.

It is known to use means for coloring hair, which are called Dye component so-called oxidation colors such as aminophenol, dihydroxybenzene and in particular phenylenediamine. Depending on the type of dyes used However, the fastness properties are such as light fastness, sublimation fastness and color fastness not sufficient for practical needs.

The invention is based on the object of hair colorants of oxidation colors to produce, which have improved properties. the new means for coloring human hair are characterized in that these as paraffin component senzene derivatives with 4 - 6 substituents in the form of alkoxy, Hydroxy, amino and alkylamino groups contain. So there are a large number of them of substituted benzene derivatives into consideration Of these two groups have become proved to be particularly suitable.

The first group includes benzene derivatives that have the general formula correspond, where R1, R2 and R3 are -OH or -NH2, R4 and R5 are -H, -NH2 or -OH.

The following are to be mentioned in particular: 1,3-diamino-2,4-dihydroxybenzene, 1,3,5-triamino-2,4-dihydroxybenzene, 1-amino-2,3,4-trihydroxybenzene, 1,3-diamino-4,5,6-trihydroxybenzene and hexahydroxybenzene.

The second group of particularly suitable benzene derivatives includes those which contain three amino groups and at least one alkoxy group as substituents such as: 1,2,3-triamino-4-ethoxybenzene, 1,2,3-triamino-4,5-dimethoxybenzene, 1,2,3,4-tetramino-5-methoxybenzene, 1,2,3-triamino-4-hydroxy-5-methoxybenzene.

The group of benzene derivatives that are particularly suitable include also: 1,2-diamino-4,5-dimethoxybenzene, 1 amino-2,5-dihydroxy) methoxybenzene, 1-amino-2,4-dihydroxy-5-methoxybenzene, 1-amino-3,5-dimethoxy-4-hydroxybenzene.

However, there are also polyfunctional benzene derivatives such as: 1,4-dimethoxy-2,5-dihydroxybenzene, 1,4-di- (ethylamino) -2,5-dihydroxybenzene, 1,2,4-triamino-3,6-dimethoxybenzene, es , 4-dimethoxy-2,3,5,6-tetrahydroxybenzene are possible. the benzene derivatives can im The rest can be used individually or as a mixture. You can also, if necessary in the form of their salts wi. Hydrochlorides or sulfates can be used.

The agents according to the invention are in the form of aqueous solutions, as pastes or emulsions, but if desired also prepared in test form. They show good compatibility with other dyes such as aromatic diamines and dihydroxybenzenes, so that they can also be combined with these dyes can. in particular, combinations with resorcinol and m-tolylenediamine have proven themselves and p-dimethylaminoaniline have been found suitable.

When using the new hair dye, it is not necessary to the oxidation of the dyes by per compounds such as H2O2, ercarbamide, melamine perhydrate, Bring about ammonium persulfate or perhydrate. Such an addition comes from this practically only in consideration if simultaneously with the dye components according to the invention Oxidation dyes are added to the hair dye that are not or not be sufficiently oxidized by atmospheric oxygen. In some cases, however, is a Addition of per compounds is not required even if dye components are used at the same time, which when used alone, an addition of per compounds require.

It is often convenient. the dyes in a wetting agent and / or detergent containing cream to incorporate, as such agents are mainly used in practice Find.

The new hair dyes can be used with any network or. Detergents, in particular anionic or nonionic, are mixed.

In particular, alkylbenzenesulfonates are used as wetting agents or detergents, Alkyl sulfates, alkyl sulfonates, fatty acid ethanol amides, addition products of ethylene oxide of fatty alcohols or alkylphenols in question.

The abovementioned dyes can also be absorbed in a mixture good with such means. You can oje hair dye in the form of shampoos, especially cream-like shampoos, which are often desired in practice, produce..

The agents according to the invention can furthermore contain thickeners such as E.g. thylcaltuloße, starch, higher fatty alcohols, petrolatum, paraffin oil and fatty acids as well as perfume oil or hair care products such as pantothenic acid and cholesterol mixed in been.

The additives are used in the amounts customary for this purpose applied. In particular, amounts of 0.5 - 30% are used as wetting agent additives and as thickener additives amounts of 0.1-25 ", each based on the Overall composition, into consideration. The concentration of the dyes is depending on to the Purpose of use up to 5?, But preferably 0.1 -2 =, as well related to the entire composition.

-You can set the hair coloring agent to a pH range of 3 - 10 be; a range of 7-9.5 is preferred.

The new hair dyes have good fastness properties and also have the advantage that # they are not used with per connections need to be mixed.

The production of permanent waves for hair that has the hair dyes according to the invention were treated, possible without the practical a change in color takes place.
