COMPOSITION COMPRISING MACROCYCLIC TETRA-AMIDO N-DONOR METAL-LIGAND COMPLEX AS BLEACHING CATALYST

摘要

The present invention relates to compositions comprising a macrocyclic tetra-amido N-donor metal-ligand complexes as a bleaching catalyst. It provides a laundry bleaching composition comprising: a) a macrocyclic tetra amido N-donor metal-ligand complex (preferably, 5,6-benzo-3,8,11,13-tetraoxo-2,2,9,9,12,12-hexamethyl-1,4,7,10- tetraaza-cyclo-tridecane), and b) a builder, said composition being substantially devoid of any added peroxygen bleach or a peroxy-based or peroxyl-generating bleach system.
