PROBLEM TO BE SOLVED: To provide an O/W-type emulsion having transparency and stability, while improving skin absorption of a fat-soluble component which is an active ingredient of an external preparation for skin or a cosmetic and preferably comprises carotenoids, vitamin C derivatives, and vitamin E's, to provide a method for producing the same, to provide the external preparation for skin into which the same is mixed, and to provide the cosmetic. SOLUTION: This method for producing the O/W-type emulsion comprises dissolving a glycerol fatty acid ester in a polyhydric alcohol, then adding the fat-soluble component thereto and together mixing the components, further adding a sucrose fatty acid ester dissolved in water thereto and together mixing them, and finally subjecting them to high-pressure emulsification, so that the O/W-type emulsion which has an average particle diameter of≤0.1μm, is highly stable and transparent, and has good absorption into the skin is obtained. The O/W-type emulsion is used for the cosmetic and the external preparation for skin. COPYRIGHT: (C)2005,JPO&NCIPI
