Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair treatment composition, and more specifically, it can prevent damage to the hair during treatment, impart a good feeling to the hair, and give a color change over time. The present invention relates to a hair treatment composition such as a hair bleach that can suppress changes.

2. Description of the Related Art Conventionally, the problems to be solved by the invention
For hair bleaching, a composition containing an oxidizing agent such as hydrogen peroxide is applied to the hair as it is (one-agent type).
A so-called bleaching agent, which is applied to hair by mixing with a composition containing an alkali such as ammonia (two-component type), is widely used. Since these hair treatment agents use an oxidizing agent such as hydrogen peroxide, the hair is significantly damaged during the treatment, and therefore the suppleness of the hair after the treatment is eliminated,
There was a problem that the combing became poor, the moisture and gloss were lost due to washing the hair, the color of the hair changed over time, and the hair color became unnatural.

Therefore, the pH of the system is lowered by adding an ammonium salt to the alkaline agent (Japanese Patent Laid-Open No. 55-855).
No. 12), those containing a specific cationic polymer (JP-A-55-4384), those containing gluconic acid and the like (JP-A-59-93017), and the like. However, none of them had sufficient effects. Therefore, there has been a demand for a hair treatment agent capable of preventing damage to the hair during treatment, imparting a good feel to the hair, and causing little change in the color of the hair over time.
