Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a one-component hair treatment composition which can be conveniently used to dye hair in a bright color and is excellent in stability over time and dye stability.

[0002]

2. Description of the Related Art Unlike a hair dye that uses an acid dye, a hair dye that uses an acid dye tends to be unevenly dyed and the melanin pigment is not decolorized, which makes it difficult to dye fashionable hair and bright gray hair. was there. For this reason, Japanese Patent Application Laid-Open No. 1-175925 discloses a hair dye that can be used not only for bright gray hair dyeing, but also for fashionable dyeing, by using an acid dye and an oxidizing agent at the same time.

However, in the one-part method, the acidic dye is oxidized by the oxidizing agent, and the acidic dye is discolored, so that a stable preparation cannot be obtained for a long period of time. In the invention disclosed in JP-A-1-175925, the acidic dye is also used. It is a technology mainly based on mixing of an oxidant and an oxidant at the time of use, and there is no specific description about coexistence of an acid dye and an oxidant in one preparation, and a two-component type or a three-component type is also possible. In these two-pack type and three-pack type, the stability of the acid dye is easy to maintain, but it is difficult for beginners to use due to the complexity of mixing during use and the relationship between the mixing ratio and hair dyeing.

[0004]

SUMMARY OF THE INVENTION The object of the present invention is to provide a stable one-component type composition in which anyone can easily dye hair in a desired bright color and the dye in the preparation does not fade over time. A hair treatment composition is provided.
