Abstract:
A bleaching composition comprising:a) a monomer ligand or transition metal catalyst thereof of a ligand having the formula (I): wherein each R is independently selected from: hydrogen, F, Cl, Br, hydroxyl, C1-C4-alkylOâ€”, â€”NHâ€”COâ€”H, â€”NHâ€”COâ€”C1-C4-alkyl, â€”NH2, â€”NHâ€”C1-C4-alkyl, and C1-C4-alkyl; R1 and R2 are independently selected from:C1-C4-alkyl, C6-C10-aryl, and, a group containing a heteroatom capable of coordinating to a transition metal, wherein at least one of R1 and R2 is the group containing the heteroatom; R3 and R4 are independently selected from hydrogen, C1-C8 alkyl, C1-C8-alkyl-Oâ€”C1-C8-alkyl, C1-C8-alkyl-Oâ€”C6-C10-aryl, C6-C10-aryl, C1-C8-hydroxyalkyl, and â€”(CH2)nC(O)OR5 wherein R5 is independently selected from: hydrogen, C1-C6-alkyl, n is from 0 to 4, and mixtures thereof; and, X is selected from C&boxH;O, â€”[C(R6)2]yâ€” wherein Y is from 0 to 3 and each R6 is independently selected from hydrogen, hydroxyl, C1-C4-alkoxy and C1-C4-alkyl; and, b) the balance carriers and adjunct ingredients.
