摘要：
Metal salts of monoalkyl phosphates of the following formula ##STR1## in which each R represents a saturated or unsaturated, linear or branched hydrocarbon group having from 8 to 32 carbon atoms, and M represents an alkaline earth metal or divalent transition metal.The metal salts are particularly suitable as cosmetic powders, fillers for resins, and lubricants, parting agents and pigment dispersants for polymeric compounds. When used as cosmetic powders, the metal salts improve spreadability, moistness, smoothness, adherence, transparency and covering power of cosmetics.Preparation process of the metal salts is also disclosed.
