PROBLEM TO BE SOLVED: To provide a skin detergent composition which has a low viscosity, causes no precipitation and separation of crystals and is excellent in stability, foam volume at a low temperature, foam quality, rich feeling during massaging and squeaky feeling after rinsing.SOLUTION: There is provided a skin detergent composition obtained by filling in a foamer vessel a cleansing agent which comprises (A) 0.3 to 4 mass% of an alkyl glyceryl ether having an alkyl group having 8 to 22 carbon atoms, (B) 1 to 10 mass% of a fatty acid represented by the formula (1) or a salt thereof in which the average carbon numbers of R1 is 11.5 to 13.8, (C) 0.2 to 12 mass% of a glycerine derivative represented by the formula (2) in which R2 is -[CH2CH(CH3)O]- and each of p, q, r and s is an integer of 0 to 20 and 4≤p+q+r+s≤20 and (D) water, wherein the mass ratio [(A)/(B)] of the component (A) to the component (B) in terms of the acid is 0.05 to 1.SELECTED DRAWING: NoneCOPYRIGHT: (C)2016,JPO&INPIT
