Abstract

This invention relates to an encapsulated active substrate comprising a bleach and/or a bleach activator releasably encapsulated in a coating of at least one metal salt of an inorganic acid, said salt being soluble in an aqueous medium such that upon contacting the encapsulated substrate with the aqueous medium, the active substrate is released into said aqueous medium, characterized in that the substrate has a preliminary coating of an alkali metal carbonate or a bicarbonate and a final encapsulating coating of a metal salt of an inorganic acid. The coating technique controls the activity of the bleach or bleach activator and minimises dye damage or pinholing of the fabrics washed.
