COSMETIC COMPOSITION FOR BLOCKING ULTRAVIOLET RAYS

WIPO Patent Application WO/2017/057864

A1

The present invention relates to a cosmetic composition for blocking ultraviolet rays and, more specifically, to a cosmetic composition for blocking ultraviolet rays, containing an oil-in-water type emulsion in which an oil-phase part is dispersed in a water-phase part, wherein the oil-phase part contains: (a) at least two kinds of inorganic ultraviolet blocking agents having an average particle diameter of greater than or equal to 1 nm but less than 50 nm; and (b) at least one inorganic ultraviolet blocking agent having an average particle diameter of greater than or equal to 50 nm but less than or equal to 200 nm. The cosmetic composition for blocking ultraviolet rays according to the present invention improves the uniformity and stability of an emulsion through inorganic ultraviolet blocking agents with different average particle diameters, and thus allows the manufacture and use of cosmetic products showing excellent feeling of use and ultraviolet blocking characteristics.
