Abstract

Detergent compositions comprising photobleach delivery systems, processes for preparing them, and their methods of use, the compositions combine selected hydrophobic photobleaches, especially based on Si(IV) phthalocyanines, with selected axial ligands, with certain water-soluble polymers, nonbonded ligands, detersuve surfactants, especially certain mid-chain branched types, and non-surfactant detersive adjuncts.
