Abstract
A cosmetic comprises an alkyl phosphate represented by the formula (I): ##STR1## in which R.sub.1 and R.sub.2 independently represent hydrogen atom or an alkyl group having from 1 to 36 carbon atoms, and R.sub.3 represents an alkyl group having from 1 to 36 carbon atoms, and a cosmetic powder. The cosmetic is water-repellent in nature, unlikely to break by sweat and is readily spread on the skin with improved softness due to incorporation of the alkyl phosphate. The cosmetic is prepared by first mixing the cosmetic powder and the alkyl phosphate dissolved in an organic solvent under heating conditions. Subsequently, the solvent is distilled off to form an alkyl phosphate coating on the indivisual particles. The coated particles are mixed with other cosmetic ingredients.
