Abstract
Abstract Cationic surface-active agents which are polyhydroxylated tertiary amines or the quaternary ammonium salts thereof and which are usefully employed in cosmetic compositions, are prepared by condensing on a fatty alcohol, glycerol epihalohydrin alone or together with an epoxide to form polyhalogenated polyethers, which in turn are converted to polyhalogenated glycidyl ethers, the latter being reacted with a secondary amine to form polyhalogenated tertiary amines which are then reacted with sodium or potassium acetate in the presence of a diol to form said polyhydroxylated tertiary amines.
