Abstract
A composition containing: (a) a peroxygen compound; and (b) an activator compound corresponding to formula I: ##STR1## wherein R is hydrogen, an aryl, alkyl, alkenyl or cycloalkyl group containing 1 to 17 carbon atoms, n is a number from 1 to 8, A, B and Y, independently of one another, represent hydrogen, an aryl, alkyl, alkenyl or cycloalkyl group containing 1 to 17 carbon atoms or a hydrophilic group selected from the group consisting of --SO.sub.3 H, --OSO.sub.3 H, --PO(OH).sub.2, --OPO(OH).sub.2, --CO.sub.2 H and anions thereof and --N.sup.+ R.sup.1 R.sup.2 R.sup.3 X.sup.-, where R.sup.1, R.sup.2 and R.sup.3, independently of one another, represent hydrogen, an aryl, alkyl, alkenyl or cycloalkyl group containing 1 to 17 carbon atoms and X.sup.- represents a charge-equalizing anion, and wherein at least one of the substituents A, B or Y in the molecule is one of the hydrophilic groups.
