Abstract

A bleaching composition (10) includes a plurality of solid microparticles (12). Each microparticle includes a bleaching agent (14) encapsulated in a shell (20) which modifies the release of bleaching agent from the microparticle. The shell includes a hydrophobic material (22) and a release rate modifier (24) in contact therewith.
