Abstract
The invention provides a phase stable liquid detergent composition containing at least one insoluble oxidant, comprising: PA0 (a) a liquid phase which comprises: (i) an effective amount of at least one surfactant selected from the group consisting of anionic, nonionic, cationic, amphoteric, zwitterionic surfactants, and mixtures thereof; (ii) a liquid carrier therefor, comprising water soluble or dispersible organic solvents, water, or a mixture thereof; PA0 (b) an effective amount of a water insoluble oxidant stably suspended in said liquid phase, which maintains oxidative stability, said water insoluble oxidant being an alkaline earth metal peroxide or a Group IIB peroxide; and PA0 (c) a stabilizer which is either a source of common ions or by buffering to a pH of greater than 8.
