Patent ID: 6903060

Claim:
A bleaching composition comprising an organic catalyst compound, in conjunction with or without a peroxygen source, wherein said organic catalyst compound is selected from the group consisting of organic catalyst compounds that exhibit an organic catalyst lifetime greater than or equal to 30 minutes, said organic catalyst compounds being aryliminium zwitterions having a net charge of from about +3 to about −3, and being represented by the formula [II]: where R 5 -R 7 are independently selected from substituted or unsubstituted radicals selected from the group consisting of H, alkyl, cycloalkyl, aryl, alkaryl, aralkyl, heterocyclic ring, silyl, nitro, halo, cyano, sulfonato, alkoxy, keto, carboxylic, and carboalkoxy radicals; also present in this formula is the radical represented by the formula: where Z p − is covalently bonded to T o , and Z p − is selected from the group consisting of —CO 2 − , —SO 3 − , —OSO 3 − , —SO 2 − and —OSO 2 − and p is either 1, 2 or 3; T o is selected from the group consisting of substituted or unsubstituted, saturated or unsaturated alkyl, cycloalkyl, aryl, alkaryl, aralkyl and heterocyclic ring, provided T o is not substituted or unsubstituted methylene or a moiety that is covalently bonded to the nitrogen of formula II via unsubstituted methylene.
