BACKGROUND OF THE INVENTION
The present invention relates to a hair bleaching agent composition that has little hair damage, is excellent in hair bleaching power, and has a uniform bleaching effect.
[0002]
[Prior art]
A method of using a decoloring agent in which an alkaline agent and an oxidizing agent are mixed is known in order to decolorize the hair or remove the hair dye from the dyed hair. Further, a decolorizing agent using persulfate as an accelerator is a two-part type of persulfate, a powdery or granular composition containing a persulfate and an alkali agent and an aqueous composition containing an oxidizing agent such as hydrogen peroxide. Is used in a three-part form of a powdery or granular composition containing an aqueous composition, an aqueous composition containing an alkaline agent, and an aqueous composition containing an oxidizing agent such as hydrogen peroxide.
However, there has been a problem that hair that has been decolorized with a hair decolorizing agent that uses these persulfates is damaged, the hair is not supple, and the hair becomes cramped or combed.
