Abstract: An objective of the invention is to provide a sunscreen cosmetic that, by blending an environmentally friendly and highly water-resistant powder component instead of microplastic beads or silica, can achieve high ultraviolet protection power even when a small amount of an ultraviolet protectant is used, that moreover has the property wherein, by coming into contact with water, perspiration or the like, the ultraviolet protection effects are increased even more than those directly after being applied, and that also has an excellent texture. The sunscreen cosmetic according to the present invention contains (A) an oil phase thickener, (B) an ultraviolet protectant, and (C) a wax powder having a volume-average particle size of 1 to 30 lam.
