Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powder dye composition, and more particularly to a powder dye composition which can be stably stored for a long period of time and is suitable for preparing a hair dye composition, and a hair dye containing the composition. It relates to a composition.

[0002]

2. Description of the Related Art Oxidation dyes commonly used in oxidation hair dyes, for example, p-phenylenediamine, toluene-
2,5-Diamine, m-phenylenediamine, and the like are unstable compounds that are easily oxidized by oxygen in the air, and cause deterioration such as a decrease in purity or a blackening of appearance during storage. However, there is a problem that the material cannot be used as a raw material.

[0003] At present, these problems have been dealt with by using packaging forms that avoid contact with air or by using dyes such as sulfates and hydrochlorides.

[0004] Hair dyes containing these dyes include:
There are liquid, cream, gel, aerosol and powder forms. In hair dyes such as liquid, cream, gel, and aerosol, the dye is dissolved in the base material, and a reducing agent is further added to stabilize the dissolved dye. Is common. On the other hand, in a powdery hair dye, the dye is usually mixed with the base as it is.

[0005]

However, the use of sulfate or hydrochloride as the dye has not sufficiently improved the stability. Also, due to their properties, these oxidation dyes have problems such as caking and lumps during storage, and furthermore, there has been a problem of scattering of the dye at the stage of producing the hair dye. In particular, in the case of a powder hair dye containing a large amount of an oxidation dye, there has been a problem that the dispersibility of the hair dye itself deteriorates and production inconvenience occurs, thereby lowering production efficiency.

[0006]

Means for Solving the Problems The present inventor has made intensive studies in view of the above-mentioned circumstances, and as a result, by adding a dispersant and a small amount of oil to the oxidation dye, the stability and flying property of the oxidation dye have been improved. The present inventors have found that a hair dye composition can be prepared by a simple operation using the same at the time of use, and the present invention has been completed.

That is, the present invention relates to (A) a dye of 80% by weight or more, (B) a dispersant and (C) an oil content of 0.01 to 2.0.
It is intended to provide a powder dye composition characterized by containing by weight, and a hair dye composition containing the composition.

[0008] As a secondary effect of the present invention, as a result of improving the scattering property of the oxidation dye, the rise of the dye in preparing the hair dye composition is reduced, and the working environment is greatly improved. Furthermore, the powder hair dye composition prepared using the powder dye composition of the present invention has good dispersibility, so that inconvenience in production can be eliminated and production efficiency can be improved. Hereinafter, the present invention will be described in detail.
