Abstract
A bleach system is described that includes a peroxygen compound which is hydrogen peroxide or an inorganic substance that generates hydrogen peroxide in water, a C.sub.1 -C.sub.30 imine and a transition metal catalyst. Use of the transition metal catalyst promotes the interaction of the hydrogen peroxide and imine thereby enhancing bleach performance.
