(57) [Summary] [Object] To provide an emulsifier composition for producing an O / W emulsion excellent in stability, water resistance or water repellency, and touch. A polyglycerin fatty acid ester-based emulsifier composition comprising an ester of polyglycerin having a degree of polymerization of 4 or more and a fatty acid, and an acyl lactic acid having 8 or more carbon atoms or a salt thereof. [Effects] The emulsifier composition of the present invention does not affect the emulsification performance depending on the pH and blending components, can be emulsified at a low concentration within a predetermined range, is convenient, and can be used in a wide range of fields. . Further, by using the emulsifier composition of the present invention, it is possible to provide an O / W emulsion which is excellent in temperature stability, feel, and water resistance or water repellency. Furthermore, excellent biodegradability, lack of toxicity. |
