There is provided a process for enhancing the activity of an oxidoreductase, comprising adding to the enzyme, as an enhancer for the activity of said enzyme, a compound having formula (I) wherein R<1>-R<4> may each independently represent hydrogen, hydroxy, halogen, nitroso, formyl, carboxyl, and esters and salts thereof, carbyamoyl, sulfo and esters and salts hereof, sulfamoyl, nitro, amino, phenyl, C1-C20 alkyl, C1-C8 alkoxy, carbonyl-C1-C6-alkoxy, aryl-C1-C6-alkyl, whereby two of the groups R<1>-R<4> may be linked together by any group, and A is a five or six membered heterocyclic ring which may be optionally substituted with any of the radicals as defined for R<1>-R<4>. A bleach composition, a detergent composition and a process for inhibiting dye transfer from one fabric to another during washing are also disclosed.
