Beschreibung
Zusammenfassung:	The invention aims at providing a powder cosmetic which does not suffer from the aggregation of powder even when it contains a large amount of oily component and in which no caking of powder on the surface occurs even when pressed, and a process for the production of platy calcium sulfate dihydrate usable for the cosmetic. The process of the production includes a process for producing a powder cosmetic comprising calcium sulfate dihydrate and an oily component, and a process for producing platy calcium sulfate dihydrate which process comprises dissolving a calcium salt in an organic acid and reacting the resulting calcium solution with sulfuric acid.
