Abstract
A stable liquid peracid precursor composition for delivering a bleaching and cleaning material is provided in which the liquid peracid precursor composition combines a dispersion medium which comprises a stabilizing effective amount of a liquid matrix and an emulsifier, and a dispersed phase that comprises a peracid precursor. The bleaching and cleaning material comprises either a hydrophobic or hydrotropic generated mono- or diperoxyacid, or mixtures thereof.
