Abstract

A solid composition consisting essentially of 5-98 parts by weight of heterocyclic compounds I whereL1 is groups with a cyclic carbamate, a lactonoxy or a lactam structure,X is a carbonyl, a doubled carbonyl or a heterocarbonyl group, andR1 is an organic radical or a second moiety L1,and/or oxime esters II whereL2 is an oxime moiety whereR2, R3 and Z4 are organic radicals or linkers,L3 is the radical R1, a second oxime moiety L2 or a carboxylic ester residue, carboxamide residue, phenolate residue, vinyloxy radical, sulfonamide residue, imidazole residue, amidolactam residue, cyclic carbamate residue, lactonoxy residue or lactam residue, andm is 0 or 1,and 2-95 parts by weight of inert porous carrier materials with an internal surface area of from 10 to 500 m2/g.The solid composition described is suitable as stable bleach activator component in detergents, bleaches and cleaners.
