A foaming agent comprising an amphoteric surfactant and an N-acylamino acid surfactant which foams by being dispersed or sprayed, and provides improved foaming characteristics to foaming cosmetic compositions. In one preferred embodiment of the present invention, the foaming agent is comprised in a foaming cosmetic composition such as a hair mousse composition comprising a solvent and optical compositions such as polymer, preservative and propellant. As shown in the figure, foaming composition (8) of the present invention containing cocamidopropyl betaine and sodium lauroyl sarcosinate shows similar rheology to comparative example (A) and better foam rheology compared to comparative examples (B) and (C). |
