Abstract:
A laundry or cleaning composition comprising:(a) from 0.0001% to 99.9% of a bleach activator and/or organic percarboxylic acid;(b) from 0.001 ppm to 49% of a transition-metal bleach catalyst, said catalyst comprising a complex of a transition metal and a cross-bridged macropolycyclic ligand, wherein:(1) said transition metal is selected from the group consisting of Mn(II), Mn(III), Mn(IV), Mn(V), Fe(II), Fe(III), Fe(IV), Co(I), Co(II), Co(III), Ni(I), Ni(II), Ni(III), Cu(I), Cu(II), Cu(III), Cr(II), Cr(III), Cr(IV), Cr(V), Cr(VI), V(III), V(IV), V(V), Mo(IV), Mo(V), Mo(VI), W(IV), W(V), W(VI), Pd(II), Ru(II), Ru(III), and Ru(IV);(2) said cross-bridged macropolycyclic ligand being coordinated by four or five donor atoms to the same transition metal and comprising:(i) an organic macrocycle ring containing four or more donor atoms separated from each other by covalent linkages of 2 or 3 non-donor atoms, two to five of these donor atoms being coordinated to the same transition metal atom in the complex;(ii) a cross-bridged chain which covalently connects at least 2 non-adjacent donor atoms of the organic macrocycle ring, said covalently connected non-adjacent donor atoms being bridgehead donor atoms which are coordinated to the same transition metal in the complex, and wherein said cross-bridged chain comprises from 2 to 10 atoms; and(iii) optionally, one or more non-macropolycyclic ligands; and(c) at least 0.1%, of one or more laundry or cleaning adjunct materials.
