Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair rinse composition, and more specifically, it has an effect of gradually coloring hair without being dyed on the hands at the time of use, has an excellent conditioning effect, and has a shine on the hair and fingers. Further, the present invention relates to a foam-like hair rinse composition having significantly improved smoothness and excellent safety.

[0002]

2. Description of the Related Art Conventionally, since hair after washing has poor gloss and combability, a treatment agent called a hair rinse or a hair conditioner is applied in order to impart a conditioning effect to the hair. These treating agents generally contain a quaternary ammonium salt such as stearyltrimethylammonium chloride as a main component, and various additives are added to further enhance the effect.

On the other hand, among those who use these hair treatment compositions, there are cases where the hair becomes gray due to aging, or the hair is damaged due to brushing, perm, etc., and the natural hair color changes. . In order for these people to return the hair to the original color, it is most effective to dye the hair with a hair dye such as an acid dye or an oxidation dye. However, the operations are complicated, and it is immediately known that the hair is dyed by a third party because the color of the hair is rapidly changed, which causes a feeling of strangeness. In addition, a boundary is formed between the treated portion and new hair as the hair grows, which is not preferable in appearance. Particularly, a hair dye using an acid dye has a problem that it is very easy to dye the skin such as hands and scalp and does not easily come off once dyed. Further, the hair dye using an oxidative dye mainly containing paraphenylenediamine contains an alkali agent and hydrogen peroxide solution, and thus has a problem that the hair is significantly damaged by the treatment. Therefore, what is strongly desired is one in which the hair color changes gradually and naturally to the natural color without abrupt color change and can be dyed easily. Therefore, while imparting a high conditioning effect such as shine or finger passage to the hair by the hair treatment composition such as the above-mentioned hair rinse which is a daily lifestyle, it is easily and dyed on the skin such as hands and scalp. It is considered to be more useful if these things can be done without doing so, the complexity is eliminated.

As means for achieving these things, Japanese Patent Laid-Open No.
In JP-A-308215, a product using an acid dye and a quaternary ammonium salt is proposed, which is effective in improving the texture as a hair rinse, but it is an anionic acid dye and a cationic dye. The quaternary ammonium salt is an insoluble salt, so that sufficient dyeing power cannot be obtained, and the skin is more likely to be dyed than the hair.
Japanese Patent Application Laid-Open No. 61-78714 proposes a gray hair dye for cumulative hair dyeing using an oxidation dye such as p-phenylenediamine, but the operation is complicated and the hair is damaged. There's a problem. In addition, JP-A-2-5371
5 and JP-A-60-126114,
Attempts have been made to develop air-oxidative hair dyes using 4-diaminophenol, but with these methods, conditioning effects such as gloss and combing cannot be obtained, and a leaving time of 10 minutes or more is required. It is simply lacking, and the stability of the composition is poor, and practical application is impossible.
