Abstract
Liquid cleansing oils capable of mixing well with old makeup and being easily rinsed off with water have come into the mainstream in recent years. An object of the present invention is to provide a cosmetic composition which easily mixes with old makeup, enables the old makeup to be lifted off rapidly, demonstrates superior cleansing strength even if the skin is wet, demonstrates satisfactory ease of rinsing, has a satisfactory feel during use without leaving an oily sensation after washing, and demonstrates superior moisture dispersivity. The present invention achieves this object by comprising a nonionic surfactant and a polyvalent alcohol fatty acid ester of a fatty acid having 6 to 12 carbon atoms and a polyvalent alcohol having 2 to 4 hydroxyl groups; wherein, the total amount of monoester and diester in the ester is 50% or more, and the weight ratio of monoester to diester is 4 or less.
