PROBLEM TO BE SOLVED: To provide an emulsion composition being useful for e.g. a skin cosmetic, containing an oil-soluble ascorbic acid derivative, and showing still more improved skin permeability. SOLUTION: The emulsion composition containing an oil-soluble ascorbic acid derivative is one comprising the oil-soluble ascorbic acid derivative and a water-soluble polymer, wherein the emulsion has a volume-based mean particle diameter of 8 to 100μm. The emulsion composition having such a mean particle diameter can allow the constituent oil-soluble ascorbic acid derivative to exhibit an increased skin permeability. COPYRIGHT: (C)2006,JPO&NCIPI
