    • A laundry or cleaning composition comprising: (a) 1ppb-49% of a transition metal bleach catalyst comprising a complex of a transition metal and a cross-bridged macropolycyclic ligand in which: (1) the metal is selected from Mn(II), 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), Cr(III), Cr(IV), Cr(V), Cr(VI), V(III), V(IV), V(V), Mo(IV), Mo(V), Mo(VI), W(IV), W(VI), Pd(II), Ru(II), RU(III) and Ru(IV); and (2) the macropolycyclic rigid ligand is selected from: (i) ligand of formula (I) having denticity of 4 or 5: (ii) ligand of formula (II) having denticity of 5 or 6: (iii) ligand of formula (III) having denticity of 6 or 7; (where E = moiety (CRn)a-X-(CRn)a'; X = O, S, NR or P, or a covalent bond (especially covalent bond); for each E the sum of a + a' = 1-5( especially 2 and 3; G = (CRn)b; R = H, alkyl, alkenyl, alkynyl, aryl, alkylaryl or heteroaryl or two or more are covalently bonded to form an aromatic or hetero aromatic, cycloalkyl or heterocycloalkyl ring; D = donor atom selected from N,O, S, or P, at least two D atoms are bridgehead donor atoms coordinated to the transition metal; b = C or D or cycloalkyl or heterocyclic ring; n = 1 or 2, completing the valence of C atoms to which R moieties are bonded; n' = 0 or 1 completing the valence of D donor atoms to which R moieties are bonded; n'' = 0,1 or 2 completing the valence of B atoms to which R moieties are bonded; a, a' = 0-5, preferably a + a' = 2 or 3, the sum of all a + sum of all a' in formula (I) being 7-12, the sum of all a + a' in formula (II) being 6 (especially 8) -12, the sum of all a + a' in formula (III) being 8 (especially 10)-15 and the sum of all a + a' in formula (IV) being 10 (especially 12)-18; b = 0-9 (especially 0-5) or one or more of the (CRn)b moieties covalently bonded from any D to the B atom is absent as long as at least two (CRn)b covalently bond two of the D donor atoms to the B atom and the sum of all b is 1-5; and (iv) optionally one or more non-macropolycyclic ligands, preferably selected from H2O, ROH, NR3, RCN, OH-, OOH-, RS-, RO-, OCN-, SCN-, N3-, CN-, F-, Cl-, Br-, I-, O2-, NO3-, NO2-, SO42-, SO32-, PO43-, organic phosphates, organic phosphonates, organic sulphates, organic sulphonates, and aromatic N-donors such as pyridines, pyrazines, pyrazoles, imidazoles, benzimidazoles, pyrimidines, triazoles, and thiazoles with R being H, optionally substituted alkyl or aryl; and (b) at least 0.1% adjunct ingredient(s), preferably oxygen bleaching agent. Preferably the donor atoms in the macropolycyclic ligand are N, S, O or P, especially N or O, more especially all are N. The ligand comprises 4 or 5 donor atoms all connected to the same transition metal. The ligand comprises an organic macrocycle ring having at least 12, especially 12-20 atoms. Al, a are 2 or 3, all X are covalent bonds, a' are 0 and B are 0.1 or 2. The mol ratio of transition metal to ligand is 1:1 and transition metal is Mn or Fe.
