Abstract

Hair color based on an oxidation dye precursor reacting with peroxide contains a mixture of: (a) 1- beta -hydroxyethoxy-2,4-diaminobenzene (I); and (b) substance(s) selected from 1-( beta -hydroxyethyl)-2,5-diaminobenzene, 2-(2'-hydroxyethyl)-5-aminotoluene, N,N-bis-(hydroxyethyl)-1,4-diaminobenzene, 4-amino-3-methylphenol, 2-amino-5-diethylaminotoluene, 3-(diethylaminomethyl)-4-hydroxyaniline, 2-chloro-, 2-bromo-, 2,6-dichloro- or 2,6-dibromo-4-aminophenol, 2-amino-4-chlorophenol, 2-amino-4-methylphenol and/or 4-aminopiperidinoaniline (II) or their water-soluble salt(s).

Description

The present invention relates to a hair dye based on reacting with peroxide the oxidation dye system, which provides permanent intense hues, either as such are used, or, in combination with other developer and / or coupler substances can be used to achieve further color shades and the hair itself does not damage with short-term repeated use.

The developer substances that are still mostly used in hair dyes are 1,4-di aminobenzene (p-phenylenediamine) and 1-methyl-2,5-diaminobenzene (p-toluenediamine). The The use of these substances does indeed meet the color requirements of the users largely fair, but there are still color shades that are not fully achieved can be. In addition, these compositions can be very sensitive People, so-called "para-allergy sufferers", also cause skin irritation.

It has also been suggested to overcome these drawbacks by using alternative Ent to fix winder substances. This is possible to a limited extent through use of tetraaminopyrimidine or 2- (2,5-diaminophenyl) ethanol (cf. EP-A 7537 and EP-B 400 330); however, the color intensity of some shades has to be accepted will.

A largely optimal solution to this problem is described in EP-A 615 743 Written use of 2- (2'-hydroxyethylamino) -5-aminotoluene or its water-soluble Chen salts and the triaminohydroxypyrimidines known from EP-B 467 026, in particular 2,5,6-triamino-4-hydroxypyrimidine, 2,4,5-triamino-6-hydroxypyrimidine, 4,5,6- Triamino-2-hydroxypyrimidine or its salts, especially the sulfates, as developer sub punching achieved in hair dye.

Even so, color-technical wishes still remain open.

The invention is therefore based on the task of creating a hair dye that suitable for the production of a large number of shades, do not sensitize the skin at all de causes reaction and the hair does not, even with short repeated use harms.  

This object is achieved in that such a hair dye with a peroxide reactive oxidizing dye system, which consists of a mixture of 1-β- Hydroxy-ethyloxy-2,4-diaminobenzene or its water-soluble salts and at least one further substance selected from 1- (β-hydroxyethyl) -2,5- diaminobenzene, 2- (2'-hydroxyethyl) -5-aminotoluene, N, N-bis (hydroxyethyl) -1,4- diaminobenzene, 4-amino-3-methylphenol, 2-amino-5-diethylaminotoluene, 3- (Di ethylaminomethyl) -4-hydroxyaniline, 2-chloro-4-aminophenol, 2-bromo-4-aminophenol, 2,6-dichloro-4-aminophenol, 2,6-dibromo-4-aminophenol, 2-amino-4-chlorophenol, 2- Amino-4-methylphenol and / or 4-aminopiperidinoaniline or their water-soluble Salting.

1-β-hydroxyethyloxy-2,4-diaminobenzene is already in as a coupler substance Combination with 1,4-diaminobenzene or 2,5-diaminotoluene have been proposed and known from DE 27 37 138 C2.

Further usable in combination with the mixture according to the invention Coupler substances are preferably selected from the group 1-methoxy-2- amino-4- (β-hydroxy-ethylamino) benzene, 2-amino-3-hydroxypyridine, 2,5- Diaminopyridine, 2,6-diaminopyridine, 3-amino-2-methylamino-6-methoxy-pyridine, 2- (Dimethylamino) -5-aminopyridine, 1,3-diaminobenzene, resorcinol, 2-methylresorcinol, 4- Chlororesorcinol, 1-naphthol, 2-chloro-4-aminophenol, 2-aminophenol, 3-aminophenol, 1-methyl-2-hydroxy-4-aminobenzene, 5-amino-2-methoxyphenol, 5-amino-2- methylphenol, 2-amino-4-β-hydroxyethylaminoanisole, or their water-soluble Salt.

However, this is intended to add further developer and coupler substances by no means be excluded.

Using these compositions on a common basis become very expressive, intense, lasting after oxidation with peroxide Obtain hair colorations by adding appropriate further developer and Coupler substances can be varied to other color shades.

Also the additional use of other, known per se Developer substances are possible. There are still 5- Aminosalicylic acid and / or 1,2,4-triaminobenzene to mention.  

The total concentration of the developer substances is usually between about 0.05 and 5%, preferably 0.1 and 4%, in particular 0.25 to 0.5% and 2.5 to 3% by weight of the  Overall composition of the hair dye (without oxidizing agent), the An each related to the proportion of free base.

The preferred weight ratio of 1-β-hydroxyethyloxy-2,4-diaminobenzene to further substances mentioned are between about 1: 8 to 8: 1, preferably about 1: 5 up to 5: 1, in particular 1: 2 to 2: 1:

The coupler substance (s) as reaction partner of the developer substance (s) are in the inventions hair dyes according to the invention basically in about the same molar proportion as the Ent developer substances, d. that is, in amounts of 0.05 to 5.0%, preferably 0.1 to 4%, in particular 0.5 to 3 wt .-% of the total composition (without oxidizing agent), wherein the information relates in each case to the proportion of free base.

If desired, the compositions according to the invention can also contain so-called nu anceure for fine adjustment of the desired color, especially direct ones Dyes.

Such nuances are, for example, nitro dyes such as 2-amino-4,6-dinitrophenol, 2- Amino-4-nitrophenol, 2-amino-6-chloro-4-nitrophenol, etc., preferably in amounts of et wa 0.05 to 2.5%, in particular 0.1 to 1% by weight of the color composition (without oxi dation means).

The hair colorants according to the invention can be the basic and Contain additives, conditioning agents, etc., which the expert from the prior art nik known and for example in the monograph by K. Schrader, "Fundamentals and Recipe turen der Kosmetika ", 2nd edition (Hüthig Buch Verlag, Heidelberg, 1989), pp. 782 to 815, be are written. They can be used as solutions, creams, gels or in the form of aerosol Preparations are available; suitable carrier material compositions are known from the prior art Technology well known.

The oxidation dye precursor with an oxi is used for application dation agent mixed. The preferred oxidizing agent is hydrogen peroxide, for example in 2- to 6-percent concentration.

However, other peroxides such as urea and melamine peroxide can also be used will.  

The pH of the ready-to-use hair dye, d. H. after mixing with peroxide, can both in weakly acidic, d. H. a range from 5.5 to 6.9, in neutral as well as in alkaline range, d. H. are between pH 7.1 and 10.

Various exemplary embodiments are explained below to explain the invention ben.
