Description

  The present invention relates to a hair cosmetic composition, and more particularly to a hair cosmetic composition in which a plurality of agents are mixed and foamed by shaking. The hair cosmetic composition of the present invention includes, for example, hair dye compositions such as an oxidative hair dye composition and a hair bleaching / destaining agent composition.

For example, Patent Document 1 and Patent Document 2 listed below are hair dyes such as multi-agent hair dyes such as oxidative hair dyes and hair bleaching agents, in which each agent is mixed and foamed by shaking in a container. A material composition is disclosed.

  In the conventional foamed hair cosmetics of the mixed foaming method by shaking, there is a problem that the foam retention after foaming is insufficient due to the tendency of defoaming and foam quality deterioration based on the passage of time after foaming. was there. In order to solve these problems, it is common to increase the viscosity of hair cosmetics. However, when the viscosity of the agent constituting the hair cosmetic is increased in advance, good foaming becomes difficult with the mixed foaming method by shaking.

  On the other hand, the applicant of the present application pays attention to the property that the anionic polymer selected from the acrylic acid polymer thickens when it changes from acidic to alkaline, and blends this anionic polymer into an acidic agent. Has developed a hair cosmetic composition in which a plurality of agents are mixed and thickened during foaming (Patent Document 3).
