Bleaching compositions are disclosed which comprise a hypohalite bleach, and an organic catalyst according to any of the following formulae: <CHEM> or a mixture thereof, wherein R1 is -COO<->M<+>, or a saturated or unsaturated, linear or branched hydrocarbon chain being substituted by 1 to 20 carboxylic groups -COO<->M<+> and M is H or an alkali metal, R2 is H, -COO<->M<+>', a substituted or unsubstituted, saturated or unsaturated, linear or branched hydrocarbon chain having from 1 to 20 carbon atoms or a saturated or unsaturated, linear or branched hydrocarbon chain being substituted by 1 to 20 carboxylic groups -COO<->M<+> and M is H or an alkali metal, and wherein the phenyl rings each independently bare in one or more positions -H, -COO<->M<+>, -Cl, -Br, -SO3M, -NO2, -Rf, -ORf wherein Rf is a substituted or unsubstituted, saturated or unsaturated, linear or branched hydrocarbon chain having from 1 to 20 carbon atoms. A method of treating fabrics with such a composition is also disclosed. |
