Abstract

Abstract A solid detergent composition, suitable for use in personal hygiene, having improved slough loss and wear rate characteristics is presented. This solid detergent compositions contains: (A) 40 to 89.9% by weight of at least one linear alpha-olefin sulfonate having 12 to 28 carbon atoms, (B) 10 to 60% by weight of at least one, tertiary amine oxide having general formulae (I) and (II) ##STR1## wherein R 1 represents an alkyl group having 16 to 24 carbon atoms, R 2 represents an alkyl group having 1 to 11 carbon atoms, R 3 represents an alkyl group having 1 to 3 carbon atoms, R 4 and R 5 independently represent an alkyl group having 12 to 24 carbon atoms and R 6 represents an alkyl group having 1 to 3 carbon atoms, and (C) 0.1 to 20% by weight of water.
