Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a hair dye composition based on a developer / coupling agent system that reacts with peroxide.

[0002]

2. Description of the Related Art The color developers most commonly used in hair dye compositions are still 1,4-diaminobenzene (p-phenylenediamine) and 1-methyl-2,5-diaminobenzene (p-). Toluylenediamine). However, the application of these substances is generally not appropriate. because,
This is because these substances can lead to cutaneous hypersensitivity for very sensitive people (called "paraallergic people").

Until now, attempts have been made to solve this problem by using other developers. For example, tetraaminopyrimidine or 2- (2,5-diaminophenyl) ethanol (European Patent Application No. 7
537 and European Patent No. See 400 330)
Can be solved to some extent.

A suitable solution to this problem, namely a method which does not cause skin hypersensitivity and which can change the color tone in a very wide range, is described in European Patent No. No. 467 026, using hydroxytriaminopyrimidines as developers in hair dye compositions.

[0005]

However, when tetraaminopyrimidine or 2- (2,5-diaminophenyl) ethanol is used as the color developer, both the color intensity and the wide range of color tone are satisfactory. It shouldn't be. Further, when hydroxytriaminopyrimidines are used as the color developer, the coloring effect is, for example, German Patent Application No. 41 15 148, European Patent Application No. 542 129, German Patent Application No.
44 00 757, European Patent Application No. 657
158, or German Patent Application No. 42 199
As described in No. 81, it can be improved by using a combination of specific coupling agents, but the effect is not always sufficient.

The present invention therefore provides a hair dye composition comprising a developer / coupling agent suitable for preparing an impressive, vibrant and persistent orange-red shade; and said developer and An object of the present invention is to provide a hair dye composition that can obtain a color tone different from orange-red by appropriately changing the coupling agent.

[0007]

DISCLOSURE OF THE INVENTION As a result of intensive studies conducted by the present inventors in view of the above situation, 4-aminophenol and / or 5-aminosalicylic acid, 5-amino-2-methylphenol and 4-amino- The inclusion of a peroxide-reactive developer / coupling agent system in the hair dye composition, including a mixture with 3-methylphenol, gives an impressive, vibrant and persistent orange-red or other The present invention has been completed by finding that it is possible to obtain a hair dye composition having a color tone.

That is, the present invention provides a hair dye composition containing a developer / coupling agent system which reacts with peroxide, comprising: a) 4-aminophenol and / or 5-
The present invention provides a hair dye composition containing aminosalicylic acid, b) 4-amino-3-methylphenol, and c) 5-amino-2-methylphenol.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION In the hair dye composition of the present invention,
c) 5-Amino-2-methylphenol acts as a coupling agent. Further, b) 4-amino-3-methylphenol acts both as a color developer and as a coupling agent. In principle, as a developer in a hair dye composition, 4-
Using aminophenol is similar to using 4-aminosalicylic acid (European patent application No. 34.
5 728) generally known. However, this does not include the composition according to the invention for obtaining an unexpected coloring effect as described above.

With this composition for human hair, an impressive, intense, essentially orange-red color is obtained after the oxidation reaction with peroxide. Further, the coloring can be changed by adding an appropriate coupling agent to obtain a different color tone.

Particularly as such a coupling agent,
Examples thereof include resorcinol, 2-methylresorcinol, 4-chlororesorcinol, 3-aminophenol, 2-aminophenol, 2-amino-4- (β-hydroxyethyl) aminoanisole, α-naphthol and water-soluble salts thereof. However, these are examples and do not prevent the additional use of other coupling agents.

Furthermore, it is also possible to additionally use conventionally known color developers. In addition to the substances mentioned above, European Patent No. 467 026, hydroxytriaminopyrimidines such as 2,4,5-triamino-6-hydroxypyrimidine, 4,5,6-triamino-2-hydroxypyrimidine, especially their sulphates. Can be used.

The concentration of the developing agent is about 0.05 to 5% by weight, preferably 0.1 to 4% by weight in the entire composition (excluding the oxidizing agent).
%, Particularly preferably 0.25 to 3% by weight, most preferably 0.5 to 2.5% by weight. The concentration (% by weight) is the concentration in terms of free base.

The content of the coupling agent as a reaction agent for the color developing agent is approximately the same as that of the color developing agent in the hair dye composition of the present invention. That is, it is 0.05 to 5.0% by weight, preferably 0.1 to 4% by weight, and particularly preferably 0.5 to 3% by weight, based on the total composition (excluding the oxidizing agent).

As already mentioned, it is possible to additionally use further known coupling agents, if desired or necessary to obtain a certain coloring effect,
Sometimes useful. Further, the composition of the present invention has a so-called shade additive (shadin) for the purpose of adjusting a desirable color tone.
It may also include direct dyes.

Examples of such color tone additives include nitro dyes such as 2-amino-4,6-dinitrophenol, 2-amino-4-nitrophenol, 2-amino-6-chloro-4-nitrophenol and the like. In the hair dye composition (but excluding the oxidizing agent), preferably about 0.05-2.
5% by weight, particularly preferably about 0.1 to 1% by weight.

The compositions of the present invention can be formulated according to the state of the art or eg "Grundlagen Rezp".

Carrier materials, additives, conditioning agents, etc. commonly used in such compositions may be included, as known to the expert by the description in the article of 82-815, Heidelberg, 1989. They are formulated as solutions, creams, gels, or aerosols, suitable carrier compositions for which are well known in the art.

The oxidative dye precursor composition of the present invention is mixed with an oxidizing agent. A preferred oxidizing agent is hydrogen peroxide, and it is preferable to use it at a concentration of 2 to 6%, for example. However, other peroxides such as urea peroxide and melamine peroxide may be used.

The pH of the hair dye composition at the time of use, that is, the hair dye composition of the present invention after being mixed with peroxide is
A weakly acidic range, that is, a range of 5.5 to 6.9, or a neutral range, or an alkaline range, that is, 7.
You may adjust in the range of 1-9.5.
