ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention concerns a composition for coloring keratin fibers, particularly human hair, said composition containing 3-(2,4-diaminophenoxy)-1-propanol and at least one p-phenylenediamine derivative, 4,5-diamino-1H-pyrazole derivative or p-aminophenol derivative, and a method for coloring keratin fibers.
Oxidation dyes have attained essential importance in the field of hair coloring. The color is created by reaction of certain developers with certain couplers in the presence of an oxidant.
Oxidation dyes intended to be used for coloring human hair must meet numerous special requirements. Said dyes must be toxicologically and dermatologically harmless and non-sensitizing and they must produce colors of the desired intensity.
The hair colors must remain stable for at least four to six weeks. It is also expected that the hair colorations will remain stable when other cosmetic treatments are applied, such as shampooing or hair restyling. The hair colors should also be resistant to external effects such as light and weather as well as to perspiration and mechanical abrasion.
It is also necessary to be able to create a wide range of different color shades by combining appropriate developers and couplers.
The preparation of stable blue and reddish color shades presents a particular problem. Blue-coloring hair dye couplers together with yellow and red color components are needed for producing natural-looking hair colorations. Fashionable reddish hair colors, on the other hand, are created by use of an excess of the red color component.
The stability of the hair colors in both the blue and the red range, however, still leaves much to be desired, particularly as regards the action of organic acids and perspiration.
SUMMARY OF THE INVENTION
Surprisingly, we have now found that with a combination consisting of the coupler 3-(2,4-diamino-phenoxy)-1-propanol and at least one developer selected from the group consisting of certain p-phenylenediamine derivatives, 4,5-diamino-1H-pyrazole derivatives and p-aminophenol derivatives, it is possible to prepare hair colorants which, compared to the prior art, present substantially improved resistance to organic acids and perspiration besides outstanding washing and light fastness.
The preparation of 3-(2,4-diaminophenoxy)-1-propanol dihydrochloride and the use thereof in hair colorants are known from U.S. Pat. Nos. 4,259,261 and 4,329,504.
The object of the present invention is a composition for coloring keratin fibers, particularly human hair, based on a developer-coupler combination, characterized in that it contains as the coupler 3-(2,4-diaminophenoxy)-1-propanol and as the developer
