[Means for solving the problem]
[0005] The present inventors have discovered that an emulsion cosmetic obtained by combining an organic UV absorber, a hydrophobically treated metal oxide, a specific polyhydric alcohol that is compatible with the organic UV absorber, and a chain silicone of a specific viscosity spreads well when applied to the skin, and imparts a natural gloss and three-dimensional appearance to the finish of the skin (cheeks) immediately after application.
[0006] The present invention relates to a composition comprising the following components (A), (B), (C) and (D): (A) an organic ultraviolet absorber, (B) a chain silicone containing at least (B1) a chain silicone having a viscosity at 25°C of 30 to 10,000 mPa·s; (C) one or more polyhydric alcohols selected from PEG / PPG / polybutylene glycol-8 / 5 / 3 glycerin, PPG-9 diglyceryl, dipropylene glycol, and pentylene glycol; (D) Hydrophobized metal oxide The present invention relates to an emulsion cosmetic containing the above.
