摘要:
A cationic surfactant of the formula ##STR1## wherein R' represents a hydrocarbon radical containing up to 30 carbon atoms and derived from lanolin, natural waxes or resin acids, n is a number between 0.5 and 10, and R.sub.1 and R.sub.2 each independently represent lower alkyl or lower hydroxyalkyl, or together form a heterocycle such as morpholinyl or piperidinyl, is used to prepare cosmetic compositions for application to the skin or hair. Preferably, R' in the surfactant is derived from the alcohols of lanolin and hydrogenated lanolin.
