Abstract:
PROBLEM TO BE SOLVED: To obtain a makeup cosmetic which makes best use of the advantages of the conventional defocus making, and can cover its disadvantages, e.g. insufficient covering power, by making the cosmetic include spherical particles and particles treated with a perfluoroalkyl.
SOLUTION: This cosmetic contains (A) spherical particles, which may be optionally surfacetreated and (B) particles treated with a perfluoroalkyl. The preferable examples of the component A include particles of nylon, silica and acrylic resin which may optionally have a hollow structure. The component A may be surface-treated with silicone, metal soap or the like. The component B is treated with alkyl trialkoxysilane or the like, to chemically modify the particle surfaces to have an alkyl group of perfluoroalkyl structure. The cosmetic contains the component A preferably at 10 to 90 wt.%, and component B at 0.1 to 50 wt.%.
