Abstract
A fabric bleaching composition comprising a peroxy compound and a specified manganese complex is disclosed, as well as a process for bleaching and/or cleaning a fabric by contacting it with said fabric bleaching composition.
Claims34
A fabric bleaching process comprising contacting a fabric to be bleached with an effective bleaching amount of a fabric bleaching composition comprising
- a) a peroxy compound;
- and
- b) 0.0005 to 0.5%, by weight of manganese, of one or more water-soluble manganese complexes having one of the formulae (5) through (8), (11) through (15), (17) or (18):
- ##STR36## in which, in formulae (5),(6) through (8), (11) through (15), (17) or (18):
- R.sub.1 is hydrogen, alkyl, cycloalkyl, aryl, each of which is optionally substituted;
- R.sub.5 is hydrogen, alkyl, alkoxy, each of which is optionally substituted, halogen, cyano, N(alkyl).sub.2, N.sup.+ (alkyl).sub.3, wherein the alkyl groups are optionally substituted, or a water-solubilizing group;
- Y is optionally substituted alkylene or cyclohexylene;
- n is 0, 1, 2 or 3;
- M is hydrogen, an alkali metal atom, ammonium or a cation formed from an amine;
- m is 2 or 3;
- q is 0, 1, 2or3;
- and
- A is an anion, with the proviso that in the formula (5):
- R.sub.5 is optionally substituted alkoxy, halogen, cyano, N(optionally substituted alkyl).sub.2 or N.sup.+ (optionally substituted alkyl).sub.3 ;
- and R.sub.1, q and A are as defined above.
