Disclosed are monopersulfates of nitrogen containing heterocyclic (poly)percarboxylic acids of formula:
wherein:
R represents hydrogen or alkyl, (hetero)cycloalkyl, (hetero)aryl, alkylaryl or arylalkyl, said groups being optionally substituted, a carboxylic group or a percarboxylic group, or any other substituents non-reactive in the presence of the percarboxylic group;
R¹ represents an alkyl group having more than 5 carbon atoms;
n is selected from 0,1 and 2;
m is selected from 1, 2 and 3; and the heterocyclic ring may optionally be condensed with at least one further (hetero) aromatic or (hetero)cycloalkyl ring. Also described is a process for the preparation of said salts and their use as bleaching agents.
