BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an acidic hair dye composition for hair, and in particular, satisfies the essential conditions as an acidic hair dye such as dyeing property and wash resistance, while providing a good feeling after use. The present invention relates to an acidic hair dye composition for finishing hair.

2. Description of the Related Art Conventionally, as a hair dye composition for hair, an oxidative hair dye which dyes hair by utilizing an oxidative polymerization reaction and a hair dye in an acidic region using a legal dye are used. There is an acidic hair dye that does. Of these, the acidic hair dye is usually a one-pack type, and therefore has an advantage in terms of simplicity in use as compared with an oxidative hair dye that requires a two-pack type. However, the optimum pH range is 1.5 to 4.5 (this range is preferable in order to obtain good dyeing property and wash resistance, and the average is around 3), which is considerably low among ordinary hair cosmetics. Therefore, there is a drawback that it is difficult to satisfy the feeling of use. Recently, a hair dye that also serves as a conditioner after shampooing has been attracting attention. This product is used as a rinsing feeling while weakening the coloring effect to the extent that it does not stain the hand with respect to ordinary hair dyes, and a feeling after use is required.

On the other hand, as the function of the rinse, two functions of improving the combing of hair after drying and suppressing the generation of static electricity are important. Commonly used for this purpose are cationic surfactants. However, if an attempt is made to add a cationic surfactant to the acidic hair dye composition, an anionic component that is conventionally generally contained as a coloring agent in the hair dye composition reacts with the cationic surfactant. Then, there was a problem that it made a complex and aggregated. For this reason,
It was not possible to use cationic surfactants as rinse-effect agents in acidic hair dyes. The present invention has been made in response to such conventional circumstances and recent trends, and rinses a cationic surfactant while satisfying the essential conditions for an acidic hair dye, such as dyeing property and wash resistance. An object of the present invention is to provide an acidic hair dye composition for hair, which has a higher rinse effect by being added as an effect agent.

It is in the range of 05 to 0.7, preferably 0.1 to 0.3.
Is. When it is less than 0.05, the rinse effect is deteriorated due to too little cationic compound. On the other hand, when the molar ratio exceeds 0.7, the produced complex of the cationic compound and the anionic component hinders the stability of the system and remarkably lowers the dyeing property.

The composition system of the present invention comprises a cationic compound in an anionic colorant, and the complex formed is stabilized in the presence of a quantitatively predominant anionic surfactant. It is considered to be a live system. Therefore, when the ratio of the cationic compound to the anionic component is increased, the amount of the complex is increased, and it becomes cloudy without being completely dissolved. However, when the amount of the cationic compound is increased and the amount becomes more dominant than the anionic component, the Dissolved by the compound, the system becomes a lysed system again. However, in this case, the dyeability is reduced due to the inhibition by cations.
