Description

Skin detergent composition

The present invention relates to a skin cleanser composition.

In recent years, various detergents have been developed in response to the diversification of makeup cosmetics and consumer demand. For example, in Patent Documents 1 and 2, a rinse-type detergent is disclosed which transmits a specific water-soluble polymer to a detergent and imparts special liquid properties, thereby improving the massage property of the detergent. Improves the cleansing properties of make-up dirt and sebum dirt.

On the other hand, Patent Document 3 discloses a rinse-free detergent composition capable of removing cosmetic soil and skin dirt, which is less irritating to the skin and the eye mucosa. Further, Patent Document 4 describes a rinse-free type detergent which is obtained by impregnating a sheet with a nonionic surfactant having an average HLB of 10 to 15 and a liquid oil or a polyol. Clean the skin and wipe off the dirt on the skin.
