PURPOSE:To obtain an emulsifier which is soft to skin and stable with the lapse of time, by combining a specific phosphate ester neutralized by a basic substance and a specific nonionic surfactant as the emulsifier. CONSTITUTION:As an emulsifier, a pnosphate ester which is partially or completely neutralized by a basic substance, wherein said phosphate ester comprises a phosphate monoester shown by formulaIand a phosphate diester shown by formula II (wherein R1 and R4 are each a 12-24 C branched saturated hydrocarbon group, R2 and R3 are each an ethylene or propylene group, m, n are each 0-30) in a mole ratio of 100:0-70:30 and a nonionic surfactant with HLB of 6 or less are combined. This emulsifier is weakly acidic or neutral and soft to skin and extremely stable with the lapse of time. |
