[origin: EP0879875A2] Ionic or ionisable (poly)oxaacyloxy-benzene compounds of formula (I) are used as activators for especially inorganic peroxygen compounds in oxidation, laundry, cleaning or disinfectant solutions; in which R<1> = 1-5C alk(en)yl, an aryl or 3-10C cycloalkyl group, optionally substituted by 1-5C alk(en)yl, or a group of formula (II); R<2> = 1-10C alkylene, alkenylene and/or arylene; X = an ionic or ionisable group; and n = 1-10. Also claimed are (a) laundry agents, detergents and disinfectants containing (I) as bleaching activator; and (b) a method of activating peroxygen compounds (III) with (I).
