Abstract:
1. A bleaching composition comprising a metal-containing bleach catalyst, an anionic surfactant, a cationic organic catalyst compound of the formula: where the net charge is from about +3 to about −3; m is 1 to 3 when G is present and m is 1 to 4 when G is not present; n is an integer from 0 to 4; and each R 20 is independently selected from a substituted or unsubstituted radical selected from the group consisting of H, alkyl, cycloalkyl, aryl, fused aryl, heterocyclic ring, fused heterocyclic ring, nitro, halo, cyano, sulfonato, alkoxy, keto, carboxylic and carboalkoxy radicals, and any two vicinal R 20 substituents may combine to form a fused aryl, fused carbocyclic or fused heterocyclic ring; R 18 may be a substituted or unsubstituted radical selected from the group consisting of H, alkyl, cycloalkyl, alkaryl, aryl, aralkyl, heterocyclic ring, silyl, nitro, halo, cyano, sulfonato, alkoxy, keto, carboxylic and carboalkoxy radicals; R 19 may be a substituted or unsubstituted, saturated or unsaturated, radical selected from the group consisting of H, alkyl, cycloalkyl, alkaryl, aryl, aralkyl and heterocyclic ring; G is selected from the group consisting of: (1) —O—; (2) —N(R 23 )—; and (3) —N(R 23 R 24 )—; R 21 -R 24 are substituted or unsubstituted radicals independently selected from the group consisting of H, oxygen, linear or branched C 1 -C 12 alkyls, alkylenes, alkoxys, aryls, alkaryls, aralkyls, cycloalkyls and heterocyclic rings; provided that any of R 18 , R 19 , R 20 , R 21 -R 24 may be joined together with any other of R 18 , R 19 , R 20 , R 21 -R 24 to form part of a common ring; any geminal R 21 -R 22 may combine to form a carbonyl; any vicinal R 21 -R 24 may join to form unsaturation; and wherein any one group of substituents R 21 -R 24 may combine to form a substituted or unsubstituted fused unsaturated moiety; X − is a suitable charge-balancing counterion; and v is an integer from 1 to 3 and, optionally, a peroxygen source.
