(57) 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.
