Abstract (en)
[origin: WO9616148A1] There is provided a peroxyacid bleach precursor composition, and detergent composition containing it, comprising: a) a particulate peroxyacid bleach precursor of a size less than 100 mu m and selected from precursors which produce under perhydrolysis hydrophobic peroxyacid whose parent carboxylic acid has a critical micelle concentration less than 0.5 moles/litre; and b) a water-soluble organic acid compound; wherein said precursor and said organic acid are in close physical proximity. The compositions of the invention show enhanced storage stability as well as an enhanced perhydrolysis rate.
