PURPOSE:To readily obtain a high-quality solid powdery cosmetic without requiring much time for mixing and stirring, by stirring and mixing a powdery cosmetic base material with a fluorocarbon, filling the resultant mixture in a container and volatilizing the fluorocarbon. CONSTITUTION:A fluorocarbon having <=110 deg.C boiling point is stirred and mixed with a powdery cosmetic base material to provide a granular or powdery sub stance, which is then filled in a cosmetic container. The fluorocarbon is subse quently volatilized and molding is carried out to afford the aimed substance. The amount of the blended fluorocarbon is 20-80wt.% expressed in terms of weight concentration in mixing. The fluorocarbon is a colorless, transparent and inert liquid having extremely low surface tension and excellent permeability without dissolving most of cosmetic base materials. Fluorinert FC-72(R) manufac tured by Sumitomo 3M Ltd. is exemplified as the fluorocarbon. |
