Abstract
A bleach precursor compound, its peroxygen acid derivative, and detergent compositions containing these materials are disclosed herein. The bleach precursor structurally comprises a quaternized ammonium or phosphonium group linked to a carbonate moiety having a leaving group. Upon perhydrolysis in the presence of hydrogen peroxide and a basic aqueous media, there is generated a peroxycarbonic acid bleach.
