Abstract

Laundry or cleaning composition comprising: (a) a catalytically effective amount, preferably from about 1 ppb to about 99.9%, of a transition-metal bleach catalyst which is a complex of a transition-metal and a cross-bridged macropolycyclic ligand; and (b) at least about 0.1% of one or more laundry or cleaning adjunct materials, preferably comprising an oxygen bleaching agent. Preferred compositions are laundry compositions and automatic dishwashing detergents which provide enhanced cleaning/bleaching benefits through the use of such catalysts.

Dependent claims

A laundry and cleaning composition comprising;

(A) from 1 ppb to 99.9% of a metal complex comprising:
(1) a transition metal atom 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), Cr(II), Cr(III), Cr(IV), Cr(V), Cr(VI), Ni(II), Ni(III), Cu(I), Cu(II), Cu(III), 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);
and
(2) a cross-bridged macropolycyclic ligand comprising;
(a) an organic macrocycle ring that comprises at least 4 donor atoms, 2 of said donor atoms being non-adjacent donor atoms;
and
(b) a moiety that comprises a cross-bridged chain that covalently connects at least 2 non-adjacent donor atoms of said organic macrocycle ring, said covalently connected donor atoms being donor atoms that are coordinated to said transition metal;
said cross-bridged chain comprising from 2 to about 10 atoms.
(B) an oxygen bleaching agent;
and
(C) the balance to 100%, of one or more adjunct materials.

(b) a cross-bridged macropolycyclic ligand comprising:
(1) an organic macrocycle ring comprising:
(i) at least 4 donor atoms independently selected from the group consisting of N, O, S, and P;
2 to 6 of said donor atoms being coordinated to the same transition metal atom;
and
(ii) a sufficient number of non-donor atoms to separate said donor atoms from each other by covalent linkages of at least one non-donor atom;
and
(2) a moiety that comprises a cross-bridged chain, said cross-bridged chain comprising from 2 to 10 atoms and covalently connecting at least 2 non-adjacent, transition metal atom coordinated, donor atoms of said organic macrocycle ring;
said cross-bridged macropolycyclic ligand being coordinated by at least 4 of said donor atoms to said transition metal atom;
and
(c) when said cross-bridged macropolycyclic ligand comprises less than 6 donor atoms coordinated to said transition metal, a sufficient number of non-macropolycyclic ligands to complete the coordination sphere of said transition metal atom;
and
(d) when said transition metals' charge is not neutralized by said non-macropolycyclic ligands, a sufficient number of counter ions to provide said metal complex with charge neutrality;
(B) an oxygen bleaching agent, selected from the group consisting of molecular oxygen, hydrogen peroxide, a source of hydrogen peroxide, peracid, a source of peracid and mixtures thereof;
and
(C) the balance to 100%, of one or more adjunct materials.
