Abstract: Nitrogen-containing heterocyclic (poly) peroxycarboxylic acid monopersulfates which have the formula: ##STR1## wherein the symbols have the following meanings: R represents a hydrogen atom or an alkyl, (hetero)cycloalkyl, (hetero)aryl, alkyl-aryl or arylalkyl group, wherein said groups are optionally substituted, or a carboxylic group or a peroxycarboxylic group, or any other substituents non-reactive in the presence of the peroxycarboxylic group;R.sup.1 represents an alkyl group > C.sub.5 ;n is a number selected from 0,1 and 2;m is a number selected from 1, 2 and 3;and the heterocyclic ring may be in its turn condensed with at least one further (hetero) aromatic or (hetero)cycloalkylic ring. The invention relates to a preparation process for, and to their use, as bleaching agents.

Abstract: Amino-derivative (poly)peroxycarboxylic acid monopersulfates having the formula: ##STR1## wherein the symbols have the following meanings: R, R.sub.1 and R.sub.2, which may be alike or different from one another, represent hydrogen atoms, alkyl groups which may be optionally substituted with the proviso that at least one of them is a hydrogen atom;n is an integer different from 0;said --(CH.sub.2).sub.n -- group may be also interrupted by CONR.sub.3 groups;and wherein R.sub.3 represents a hydrogen atom or an alkyl or aryl group. A process for their preparation and their use as bleaching agents are also disclosed.
