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 dispersion, segregation and moisture absorption, a good storage stability and a good handleability, and a mixing with a solution. The present invention relates to a powder hair dye composition having excellent properties.

[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 oxidative hair dye usually comprises a creamy or liquid first agent containing an oxidizing dye and a creamy or liquid second agent containing an oxidizing agent, and the first and second agents are mixed at the time of use. Later, 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 an oxidizing dye in powder form and an oxidizing agent, which is mixed with a solution such as water at the time of use, and then applied to hair to dye hair. This powder hair dye is characterized in that it is easy to use and convenient for transportation and carrying.

[0003]

However, this powder hair dye has a high scattering property due to its nature, so that it is difficult to handle, a large loss occurs at the time of weighing, and there is a problem in working environment such as sucking in dust during handling. There is a problem. In addition, since the specific gravity of the raw materials being mixed is different, the content components segregate during transportation and storage, substances with high specific gravity move downward, and substances with low specific gravity move upward and become non-uniform. Each time, the problem that the hair dyeing power is different may occur. Furthermore, because the oxidation dye and the oxidizing agent are mixed at the same time,
When stored for a long time, under the influence of moisture etc., the stability of oxidation dyes and oxidizing agents decreases, and when dyeing hair, it is not possible to dye the hair with the desired color with depth,
There are problems such as a decrease in color fastness.

[0004]

Means for Solving the Problems The present inventor has made intensive studies in view of the above-mentioned circumstances, and as a result, by incorporating a dispersant and a small amount of oil into a powder hair dye composition, scattering, segregation and moisture absorption are reduced. Prevention, excellent storage stability, improved mixing with the dissolving solution, and hair dyeing that can dye hair in the desired color with depth when dyeing hair, and also have excellent color fastness The inventors have found that the present invention can be obtained, and have completed the present invention.

That is, the present invention provides a powder hair dye composition characterized by containing a dye, an oxidizing agent, a dispersant and an oil content of 0.01 to 2.0% by weight. Hereinafter, the present invention will be described in detail.

The compounding amount is 0.05 to 20% by weight based on the composition, and preferably 0.5 to 20% by weight.
-10% by weight. If the compounding amount is less than 0.05% by weight, the effect of improving dispersibility is not sufficiently exhibited, the state prior to the addition of the oil component during production becomes uneven, the addition of the oil component tends to be biased, and the particle size is further reduced. This is not preferable because it tends to cause segregation due to variation. On the other hand, even if it exceeds 20% by weight,
Rather, the dispersibility of the composition deteriorates.

If the content is more than 2.0% by weight, the handleability becomes worse due to stickiness, and the dyeing property decreases as the amount of oil added increases, The feel of the hair when washed off becomes worse.

Further, silicic anhydride can be blended for the purpose of preventing the hair dyeing power from decreasing due to moisture absorption. The compounding amount is 10.0% by weight or less, preferably 0.05 to 5.0% by weight based on the composition. If the content is less than 0.05% by weight, a sufficient effect cannot be obtained. If the content is more than 10.0% by weight, the scattering prevention effect and the stability are reduced, and the mixing property with the solution is deteriorated.
