摘要：
The invention is a sunscreen cosmetic containing (a) a specific hydrophobic zinc oxide powder, (b) decamethylcyclopentasiloxane, and (c) an alkyl trimethicone having 6 to 12 carbons.Hydrophobic powder that has the noticeable effects of low oil absorption and a low apparent specific volume is stably blended into a sunscreen cosmetic as a UV radiation dispersing agent to produce a sunscreen cosmetic that has remarkably improved ease of washability after use.
