Abstract
A cosmetic powder bar composition is disclosed. The composition, substantially oil free, comprises calcium sulfate dihydrate, mica or mica-containing composite material and polyethylene. A unique process for making this composition is also set forth. In this process a powder phase composition and a liquid phase composition are separately prepared. The two compositions are contacted to form a slurry. The slurry is placed in molds and heated to remove free water therefrom.
