Disclosed is an oil-in-water (O/W) emulsion composition which contains an oil-soluble ultraviolet absorber having a low solubility, and also has excellent in stability. The O/W emulsion composition is characterized by comprising (a) an aqueous dispersion of an oil-soluble ultraviolet absorber, (b) one or more compounds selected from nonionic surfactants and fatty acid soaps, (c) a water-swellable clay mineral, and (d) a higher fatty acid. Component (a) is preferably an aqueous dispersion of composite particles of an oil-soluble ultraviolet absorber and an organic polymer.
