Specifically, it has excellent storage stability, good dyeing power and fastness, fluidity and dispersibility are improved, and further, productivity and manufacturability. The present invention relates to a powder hair dye composition having excellent resistance.
[0002]
[Prior art]
Hair dyes are classified as temporary colorants, semi-permanent hair dyes and permanent hair dyes. Permanent hair dyes are also called oxidative hair dyes and are currently most commonly used because of their dyeing power and good color. This oxidative hair dye usually comprises a creamy or liquid first agent containing an oxidative dye and a creamy or liquid second agent containing an oxidant, and the first and second agents are used at the time of use. After mixing, it is applied to the hair and dyed. On the other hand, powdery hair dyes are known as different forms of oxidative hair dyes. This is a mixture of a powdered oxidative dye and an oxidant, which is mixed with water at the time of use, and then applied to the hair for dyeing. This powder hair dye is characterized in that it is easy to use and convenient to transport and carry.
[0003]
[Problems to be solved by the invention]
However, since this powder hair dye contains an oxidative dye and an oxidant at the same time, the stability of the oxidative dye and the oxidant is lowered when stored for a long period of time and affected by moisture, etc. At this time, there is a problem that the hair cannot be dyed in a desired color tone with a deep depth and the dyeing fastness is also lowered. Further, when a large amount of the oxidation dye is blended, the dispersibility is deteriorated, that is, it is difficult to mix uniformly, the components are easily biased, and the fluidity is also deteriorated. These are inconveniences in manufacturing, and problems such as a reduction in production efficiency occur.
[0004]
