PURPOSE: To obtain the composition excellent in foaming power and cleaning performance, having extremely low stimulating property to human skin and proper viscosity and long-term storage stability by blending a specific anionic surfactant with an amphoteric surfactant. CONSTITUTION: This composition is obtained by blending (A) a long-chain acyltaurin salt-type anionic surfactant of formula I [R<1> is a 7-19C (un)saturated hydrocarbon; R<2> is H or a 1-3C alkyl; M<1> is an alkali (ethanol)metal, ammonium, etc.] (preferably N-cocoyltaurin sodium) with (B) an alkylamino acid type amphoteric surfactant of formula II [R<3> is an 8-20C (un)saturated hydrocarbon; R<4> is H, a 1-4C alkyl, etc; M<3> is M<1> ; 1 is 1-4] (preferably N-lauryl-/β-alanine sodium, etc.). Furthermore, the component Ais preferably blended with the component B so that the weight ratio of the component A to the component B become (5:1) to (1:5) and total amount of the components A and B become 1-10wt.% based on 100wt.% of the composition. |
