Abstract:
1. A liquid cleaning composition comprising: a) from 0.1% to 20% by weight, of an oxidising agent; and b) from 0.001% to 10% by weight, of a radical scavenger, said scavenger selected from the group consisting of: wherein R 20 is the moiety —COOM or —SO 3 M, wherein M is hydrogen or a metal; R 24 , R 25 , R 26 , and R 27 are each independently C 1 -C 10 linear or branched alkyl, —OR′ wherein R′ is C 1 -C 20 linear or branched alkyl, —COOM, —SO 3 M, —Cl, —Br, —NO 2 , and mixtures thereof; R 28 is hydrogen, C 1 -C 10 linear or branched alkyl, —OR′ wherein R′ is C 1 -C 10 linear or branched alkyl, —COOM, —SO 3 M, —Cl, —Br, —NO 2 , and mixtures thereof; (iii) homopolymerx or copolymers comprising units having the formula: wherein R 31 is the moiety hydrogen, C 1 -C 10 linear or branched alkyl, —OR′ wherein R′ is C 1 -C 20 linear or branched alkyl, —OH, —COOM, —SO 3 M, —Cl, —Br, —NO 2 , and mixtures thereof; wherein M is hydrogen or a metal; each R 32 is independently hydrogen, C 1 -C 10 linear or branched alkyl, —OR′ wherein R′ is C 1 -C 20 linear or branched alkyl, —COOM, —SO 3 M, —Cl, —Br, —NO 2 , and mixtures thereof; R 1 and R 2 are each independently selected from —C(R 31 ) 2 —, —CO—, —C(O)O—, —C(O)NH—, —O—, —N + (R 31 ) 2 —; (iv) and mixtures thereof.
