Abstract

Stabilized compositions employing a binding system for improving shelf stability of an activated bleach composition containing a peroxygen source and a catalyst activator are disclosed. Stabilized compositions employ a binding system comprising an anionic surfactant for a solid formulation of a catalyst activator and peroxygen source to provide shelf stability for an activated bleach composition. Methods of formulating and use are further disclosed.
