Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a hair dye composition having good stability, easy mixing of one agent and two agents, good dyeing and excellent feel of hair after dyeing. Regarding

[0002]

2. Description of the Related Art Conventionally, a hair dye is composed of a first agent containing an oxidizing dye intermediate and a second agent containing an oxidizing agent.
A dosage form of oxidative hair dye is widely used. The oxidative hair dye is one in which a colorless, low-molecular weight oxidative dye intermediate is permeated into the hair and oxidatively polymerized in the hair to generate a pigment, which dyes the hair. These hair dyes are very convenient because they can dye hair in various color tones as desired and have excellent hair dyeing power.

[0003]

However, in the conventional oxidative hair dye, the hair is apt to be damaged by the hair dyeing treatment. This tendency was remarkable in a liquid hair dye in which a large amount of a solvent, a surfactant, and an alkaline agent such as ammonia were mixed in the preparation. On the other hand, the cream type hair dye can improve the drawbacks found in the liquid type to some extent, but the effect was not sufficiently satisfactory. Further, the cream type hair dye has a problem that the stability of the emulsion is deteriorated because a large amount of dye is mixed in the one agent. Therefore, until now, a large amount of thickening components such as higher alcohols and hydrocarbons have been added to ensure the stability of the preparation. However, such a product also has drawbacks such as difficulty in mixing due to the difference in viscosity between the first agent and the second agent, and difficulty in squeezing out from the tube due to increase in viscosity over time when actually used. It was It is an object of the present invention to provide a hair dye composition that does not have the above-mentioned drawbacks.

[0004]

Means for Solving the Problems As a result of intensive studies for solving the above-mentioned drawbacks, the present inventor has found that a hair dye composition comprising an acylated collagen polypeptide and a cationized polymer has good stability. It was found that the 1st and 2nd agents can be easily mixed, the dyeing is good, and the feeling of the hair after dyeing is excellent, and the present invention has been completed.
