  • Patent number: 6653269
    Abstract: A laundry composition, preferably to be used in addition to a laundry detergent, comprises an acidic peroxidic liquid, and particles suspended in the liquid. The particles comprise a protective coating around a core which includes at least one active ingredient selected from a chelating agent, a dye-transfer inhibitor, an anti-fading agent, an anti-bacterial agent, a fabric softener, a transition metal compound and an optical brightener. The particles are stable in the acidic peroxidic liquid but dissolve or disperse under alkaline washing conditions. Surprisingly incorporation of active ingredient(s) into particles appears to give better washing results than the dissolution of such active ingredients in such a liquid.
