Description

  The present invention relates to a skin cleansing composition having good foaming, foamy creaminess and excellent rinsing properties.

  Alkyl sulfates and alkyl ether sulfates are widely used as main surfactant components in aqueous detergents because of their high detergency and a large amount of foaming. However, when such a surfactant is used alone as a skin cleanser, there are problems such as a rough texture and a sufficient amount of foam cannot be obtained, and various improvement studies are underway.

  In the case of polyoxyethylene addition type alkyl sulfates that are generally used at present, it is known that the foam quality improves when used in combination with a cationic polymer or the like (Patent Document 1). However, when a cationic polymer is added to the polyoxyethylene addition type alkyl sulfate, there is a problem that nulling occurs and a refreshing feeling of use cannot be obtained.

Further, it is known that the polyoxyethylene addition type alkyl sulfate improves the rinsing property when the EO addition mole number is reduced. However, when a polyoxyethylene addition type alkyl sulfate having a small number of EO addition moles and a cationic polymer are blended, the solubility of the complex formed in the solution is lowered, so that foaming is lowered. Occurs.
