Abstract
A laundry treatment product, in the form of a single-compartment of multicompartment sachet capable of releasing its contents into the wash liquor during the laundry process, contains a particulate laundry treatment composition including a quaternary ammonium- or phosphonium-substituted bleach precursor, for example, cholyl-4-sulphophenyl carbonate, optionally together with a peroxy bleach compound and optionally together with one or more detergent ingredients. The sachet may be a self-contained whole wash product, or a bleach adjunct for use in conjunction with a separate detergent composition.
