DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an acidic hair dye composition for hair, and more particularly to a hair dye composition having satisfactory feeling after use while satisfying the essential conditions as an acid hair dye such as dyeing property and washing resistance. The present invention relates to an acidic hair dye composition for hair to be finished to a natural finish.

[0002]

2. Description of the Related Art Conventionally, as hair dye compositions for hair, there are oxidized hair dyes for dyeing hair using an oxidation-reduction reaction, and hair dyes in an acidic region using legal dyes. Perform acid hair dyes. Of these, acid hair dye
Acid dyes and alcohols (often benzyl alcohol is used), organic solvents and acids for pH adjustment (often citric acid) are used as the main components. It contains a thickening agent so that it does not drool, and since it is usually a one-part type, it has an advantage in terms of simplicity at the time of use compared to an oxidized hair dye that requires two or more parts . However, the optimum pH range is 1.5 to 4.5 (this range is preferable in order to obtain good dyeing and washing resistance, and the average is around 3), which is considerably low in ordinary hair cosmetics. Therefore, there is a disadvantage that the feeling of use is hardly satisfied.

[0003] The present invention has been made in view of such conventional circumstances, and provides a good feeling after use while satisfying the essential conditions as an acidic hair dye such as dyeing resistance and washing resistance. It is an object of the present invention to provide an acidic hair dye composition for hair that can be finished to a final thickness.

According to the present invention, by adding 0.01 to 5.0% by weight of cetanol in the acidic hair dye composition, the feel after use is greatly improved, and the dyeing property by the dye is improved. Also increase. The amount of cetanol is 0.01
If the amount is less than 5% by weight, a satisfactory feeling after use cannot be obtained. If the amount is more than 5.0% by weight, sticky properties are exhibited, and the feeling of use is deteriorated. In addition, the composition of the present invention can be applied as a rinse / hair dye combination composition after shampooing, taking advantage of the feature that it is a one-part hair dye composition.

Further, according to the present invention, when the anionic surfactant represented by the salt of the above general formula is blended in an amount of 0.01 to 5% by weight, the rinsing effect is further improved.
