Zusammenfassung:This invention relates to a process for releasably encapsulating an active substrate which comprises inter alia a bleach activator in a metal salt of an inorganic acid, said salt being soluble in an aqueous medium such that when the encapsulated active substrate is brought into contact with the aqueous medium, the active substrate is released into said medium. This invention is useful for the controlled release of bleach activators into a wash cycle and to stabilise some bleach activators which may otherwise lack stability.
