Abstract

Heterocyclic compounds I EQU R.sup.1 --X--L (I) where PA0 L is a cyclic carbamate residue, a lactonoxy residue or a lactam residue, PA0 X is an oxygen-containing group ##STR1## where A is a linker, and R.sup.1 is an organic radical or a group L, are used as activators for inorganic peroxy compounds, in particular as cold bleach activators or optical brighteners in detergents, cleaners and bleaches and in disinfectants.
