Abstract
A process for preparing a stable and anhydrous solid dispersion, containing from 20 to 95 weight percent of a fatty body, constituted of 10 to 50 weight percent of at least one wax having a melting point greater than 55.degree. C., and from 4 to 50 weight percent of a polyhydric alcohol, involves heating the fatty body and the polyhydric alcohol to a temperature between 65.degree. and 95.degree. C. and mixing the heated components in a turbine rotating at a speed greater than 1500 rpm. The resulting dispersion is employed in the production of cosmetics in stick form.
