Abstract
Abstract Detergent compositions, detergent additive products and bleaching compositions containing aliphatic peroxyacid bleach precursors of formula <CHEM> are provided, where L is a leaving group of defined formula whose conjugate acid has a pKa of from 6 to 13 and <CHEM> is a non linear acyl group, the carboxylic acid derivative of which has a logPOCT in the range from 1.9 to 4.0 (where POCT is the partition coefficient between octanol and water). New precursor compounds are provided in which <CHEM> is a C7-C17 branched aliphatic acyl group containing a linear chain of at least 5 carbon atoms extending from and including the carbonyl carbon wherein the branching is on at least the 2- and/or 3- carbon atom.
