[0002]

2. Description of the Related Art Hair dyes are widely used especially because they have a long-lasting effect and are accompanied by a bleaching effect so that they can be dyed in a lighter color tone than the original hair. There is.

There is a three-component system comprising the second agent and a third agent containing an activator such as persulfate for enhancing the decolorizing effect of hair. These oxidative hair dyes permeate an oxidative dye into the hair and oxidatively polymerize the oxidative dye with an oxidant such as hydrogen peroxide in the hair to generate a pigment, thereby dyeing the hair. Therefore, the oxidative dye in the hair dye is
An antioxidant is usually added in order to prevent oxidation by dissolved oxygen in the preparation before use.

However, it is not possible to sufficiently suppress the oxidation of the oxidative dye in the preparation only with the antioxidant that has been conventionally blended. In particular, when a large amount of an alkaline agent is added in order to enhance the decolorizing power of hair, there is a problem that coloring of the preparation occurs due to oxidation of the oxidative dye during storage of the preparation. In addition, even if the hair is dyed with a hair coloring agent that has been colored once, it will be dyed in a color different from the color of the hair dye originally prepared, and the durability after treatment It also has a problem that it is inferior.
