Abstract
A quaternary ammonium-substituted peroxycarboxylic acid bleach precursor, its quaternary ammonium peroxycarboxylic acid derivative, and bleaching-detergent compositions containing these materials are disclosed herein. The bleach precursor structurally comprises a quaternized ammonium group linked to a carboxyl moiety having a leaving group via an aromatic or heterocyclic bridging group which, upon perhydrolysis in the presence of hydrogen peroxide, generates a highly effective, quaternary ammonium-substituted aromatic or heterocyclic peroxycarboxylic acid bleach.
