Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powdery hair dye composition, and more particularly, to a composition having excellent storage stability, good dyeing power and fastness, and improved fluidity and dispersibility. The present invention relates to a powder hair dye composition having excellent productivity and productivity.

[0002]

2. Description of the Related Art Hair coloring agents are classified into temporary coloring agents, semi-permanent hair coloring agents and permanent hair coloring agents. Permanent hair dyes are also called oxidative hair dyes and are currently most commonly used due to their good dyeing power and good color retention. This oxidation hair dye usually comprises a creamy or liquid first agent containing an oxidation dye and a creamy or liquid second agent containing an oxidizing agent. After mixing, it is applied to the hair and dyed. On the other hand, powdered hair dyes are known as different forms of oxidative hair dyes. This is a mixture of a powdery oxidation dye and an oxidizing agent, which is mixed with water at the time of use and then applied to hair to dye hair. This powder hair dye is easy to use,
It has features such as being convenient for transportation and carrying.

[0003]

However, since this powder hair dye contains an oxidizing dye and an oxidizing agent at the same time, if it is stored for a long period of time and is affected by moisture or the like, the oxidizing dye or the oxidizing agent may be damaged. In addition, when dyeing hair, it is not possible to dye the hair with a desired color tone having a large depth, and the dyeing fastness is also lowered. Further, when a large amount of the oxidation dye is blended, the dispersibility deteriorates, that is, it is difficult to uniformly mix the components, the components tend to be biased, and the fluidity also deteriorates. These are inconvenient in manufacturing and cause problems such as a decrease in production efficiency.

[0004]

Means for Solving the Problems The inventors of the present invention have made intensive studies to solve the above-mentioned problems, and as a result, (A) dyes and (B)
By providing a powder hair dye composition containing an oxidizing agent and (C) a dispersant, the hair dye is excellent in storage stability, and can be used to dye hair into a deep and desired color tone when dyeing hair. The present inventors have found that a hair dye having good fastness can be obtained, and have completed the present invention. Further, by improving the flowability and dispersibility of the powder hair dye, the inconvenience in production is eliminated, and the production efficiency can be improved.
