PROBLEM TO BE SOLVED: To provide an O / W emulsion which is stable over time without containing a surfactant and which can contain a large amount of a fatty phase without losing stability. SOLUTION: In an emulsion containing an aqueous phase and an oily phase, at least one of an amount sufficient to thicken the oily phase is provided. At least one hydrophilic unit, at least one thickening copolymer having a sufficient amount of at least one hydrophobic unit to partially or completely dissolve in the oil phase, and at least one hydrophilic thickening compound And the hydrophilic unit is alpha, C 3 -C 6 monocarboxylic acids with β- ethylenically unsaturated, alpha, C 4 -C 6 dicarboxylic acids with β- ethylenically unsaturated, and are selected from monoesters or monoamide derivatives of said diacids Shall be. |
