Description

  The present invention relates to an oxidizing agent-containing composition used as a hair dye or a hair decoloring / decoloring agent and a method for using the same.

  Generally, as a hair treatment composition, a hair dye or a hair bleaching / decoloring agent that exhibits an effect by mixing a plurality of agents is known. Such a hair treatment composition is composed of, for example, a first agent containing an alkali agent and an oxidation dye, and a second agent (oxidation agent-containing composition) containing an oxidizing agent such as hydrogen peroxide. Oxidative hair dyes are known. Conventionally, an oxidant-containing composition that uses a stabilizer in order to improve the stability of the oxidant is known. For example, Patent Document 1 discloses a hair treatment agent containing hydrogen peroxide containing 1-hydroxyethane-1,1-diphosphonic acid (etidronic acid) and the like. However, since etidronic acid has a low metal sequestering ability, there is a problem that hair feel and hair dyeability after hair treatment are somewhat inferior, and a stabilizer in place of etidronic acid has been demanded. For example, Patent Document 2 discloses a hydrogen peroxide-containing composition containing pyrrolidone carboxylic acid ester or the like as a hydrogen peroxide stabilizer.
