PURPOSE:The titled cosmetic, containing ultrafine powdery zinc oxide having a specific particle diameter in a specific proportion, capable of protecting the skin from injurious ultraviolet light without whiteness, and having finish with high transparent feeling. CONSTITUTION:An antisuntan cosmetic containing ultrafine powderly zinc oxide having <=0.1mu maximum particle diameter and 10-60mmu average particle diameter in an amount of 1-30wt%. An ultraviolet light absorber e.g. a benzophenone based derivative, benzoic acid based derivative, salicylic acid based derivative, cinnamic acid based derivative, etc. of ultraviolet light scattering agent, e.g. titanium oxide, kaolin or calcium carbonate, in combination can be incorporated if necessary to shield completely the ultraviolet light. The titled cosmetic may be in any form of lotion, cream or paste, etc. Preferably, the ultrafine zinc oxide is treated by coating with a fat or oil raw material on the surface thereof, or a surfactant, etc. to improve the dispersibility and usability in incorporating the ultrafine zinc oxide in the cosmetic. |
