Novel highly water-soluble peroxyacid bleach precursor compounds are described of general formula (I), where R is methyl or ethyl, A is a C2-C6 alkylene, or phenylene group and Y is a sulphate, sulphonate quaternary ammonium or morpholinium group. Laundry bleaching and detergent compositions containing a source of alkaline hydrogen peroxide and one of said peroxyacid bleach precursor compounds provide enhanced bleaching and reduced colour and fabric damage relative to that provided by conventional precursors, at wash temperatures from 10 DEG C to 60 DEG C. |
