Bleaching (detergent) compositions are disclosed comprising a peroxide bleaching agent and a novel cationic peroxyacid bleach precursor having at least one of the following groups (A) and (B) : <CHEM> wherein R1 and R2 are each individually H, or a substituent group containing at least one carbon atom, provided that R1 and R2 are not both H. The novel bleach precursor of the cationic nitrile type shows no tendency to deliquesce under normal atmospheric conditions. |
