Abstract:
A purpose of the present invention is to provide an oil-in-water emulsion cosmetic having a fresh feeling in use like that of a skin-care cosmetic such as a milky lotion, while also allowing titanium oxide or zinc oxide, which are ultraviolet scattering agents, to be stably blended into the oil phase, and also providing excellent sunscreen effects. The present invention relates to an oil-in-water emulsion cosmetic characterized by comprising (A) an ultraviolet scattering agent having a hydrophobic surface; (B) a water-soluble alkyl-substituted polysaccharide derivative; (C) a higher alcohol; and (D) a non-ionic surfactant. The emulsion cosmetic of the present invention preferably has a viscosity, measured by a B-type viscometer at 30° C., of 12,000 mPa·s or lower.
