Description

COSMETIC PREPARATION

The present invention relates to a cosmetic (cosmetic) having excellent foam quality.

In cosmetics, cosmetics of the rinse type such as shampoo, three pigments, and body-soap have fine foaming and foaming properties when they are applied to the hair and skin, It is desired that the cosmetic material is of a non-washed type such as a hair-foam agent. When the cosmetic material is discharged from the container, the foam is fine, Which is suitable for each type of product, such as being sprayed, and the like.

In addition, in hair cosmetic compositions, since hair treated with hair dye is discolored by washing, a hair cosmetic composition which suppresses fading and keeps hair color after hair dyeing is required. On the other hand, a hair cosmetic using a special surfactant (Patent Document 1: Japanese Patent Application Laid-Open No. 7-233033, Patent Document 2: Japanese Patent Application Laid-Open No. 2002-275038) has been proposed. However, there is a problem in that the fading prevention effect is insufficient or the quality of the film is deteriorated. From the above, a hair cosmetic excellent in fading prevention effect and having a good quality is desired.

In skin cosmetics, elution, arm, shin, and the like may become whitish (whitening) under a dry environment such as a winter season due to elution of components of the stratum corneum from the washed skin. From the above, skin cosmetics with good whiteness and high whiteness of the skin are desired.
