Description

  The present invention relates to a cleaning composition. More particularly, the present invention relates to a cleaning composition applied to skin or hair.

Skin and hair cleansing compositions are generally based on anionic surfactants. Skin cleansers are mainly composed of higher fatty acid salts (soaps), and hair cleansers are alkyl sulfates or alkyl sulfonates. Alkyl ether sulfate and the like are used. It is known that a hydroxyalkyl ether carboxylate type surfactant exhibits an excellent function in terms of foaming among the anionic surfactants. However, anionic surfactants are often excellent in foaming and detergency, but have a problem in terms of irritation. On the other hand, nonionic surfactants are known as hypoallergenic surfactants. Among them, polyglycerin fatty acid esters have higher foaming properties than other polyglycerin fatty acid esters by increasing the mono-fatty acid ratio in the fatty acid part. (See, for example, Patent Document 1). However, although this limited polyglycerin fatty acid ester also has foaming properties, there is a problem that the sustainability of foam and foam quality are insufficient.
