KR960000192A - Cosmetic Pigment Treated with Sunscreen and Manufacturing Method Thereof - Google Patents

Abstract

The present invention relates to a cosmetic pigment prepared by adsorbing an ionic, nonionic or zwitterionic surfactant on a surface of a pigment to form a surfactant layer, and solubilizing a sunscreen agent on the surfactant layer, and a method for producing the same. .

Cosmetic pigments according to the present invention is excellent in the ultraviolet ray blocking effect, not having any skin irritation, and also excellent in physical properties as a pigment for cosmetics.
