Abstract

NOVELTY - A laundry and cleaning composition comprises metal complex (1-99.9 pts.wt.), an oxygen bleaching agent, and adjunct materials. The metal complex comprises a transition metal atom including manganese, iron, cobalt, chromium, nickel, copper, vanadium, molybdenum, tungsten, palladium, ruthenium; and a cross-bridged macropolycyclic ligand comprising an organic macrocycle ring comprising greater than or equal to 4 donor atoms.

USE - A laundry and cleaning composition for fabric washing, and for hard surfaces (including interiors of ovens, kitchen surfaces, or bathroom surfaces).

ADVANTAGE - The composition has superior bleaching compared to compositions not having the selected transition-metal bleach catalyst. The superiority in bleaching is obtained using very low levels of transition-metal bleach catalyst. It controls or kills microorganisms including bacteria, viruses, sub-viral particles, and molds; and destroys objectionable non-living proteins and/or peptides.

DETAILED DESCRIPTION - A laundry and cleaning composition comprises metal complex (1-99.9 pts.wt.), an oxygen bleaching agent, and adjunct materials. The metal complex comprises a transition metal atom including manganese (Mn) (II), Mn (III), Mn (IV), Mn (V), iron (Fe) (II), Fe(III), Fe(IV), cobalt (Co) (I), Co(II), Co(III), chromium (Cr) (II), Cr (III), Cr(IV), Cr(V), Cr(VI), nickel (Ni)(II), Ni (III), copper (Cu) (I), Cu(II), Cu(III), vanadium (V) (III), V(IV), V(V), molybdenum (Mo) (IV), Mo(V), Mo(VI), tungsten (W) (IV), W(V), W(VI), palladium (Pd) (II), ruthenium (Ru) (II), Ru(III), or Ru(IV); and a cross-bridged macropolycyclic ligand comprising an organic macrocycle ring comprising greater than or equal to 4 donor atoms, where 2 of the donor atoms being non-adjacent donor atoms, and a moiety that comprises a 2-10C cross-bridged chain that covalently connects greater than or equal to 2 non-adjacent donor atoms of the organic macrocycle ring, the covalently connected donor atoms being donor atoms that are coordinated to the transition metal.
