Detergent compositions inhibiting dye transfer in washing

A dye transfer inhibiting composition comprising:

• A. a metallo bleach catalyst selected from
• a) metallo porphin and water-soluble or water-dispersable derivatives thereof,
• b) metallo porphyrin and water-soluble or water-dispersable derivatives thereof,
• c) metallo phthalocyanine and water-soluble or water-dispersable derivatives thereof;
• wherein said metallo bleach catalyst is present in an amount sufficient to provide a wash solution at a concentration of from 10.sup.-8 to 10.sup.-3 molar;
• B. an amine base catalyst stabilizer capable of binding the 5th ligand of the metallo bleach catalyst and capable of reducing the rate of self-destruction of said metallo bleach catalyst;
• said catalyst stabilizer is selected from the group consisting of imidazole compounds, pyridine compounds, alkylated pyridine compounds, pyrole compounds, (C.sub.2 H.sub.5).sub.3 N, C.sub.3 H.sub.7 NH.sub.2, (C.sub.6 H.sub.11).sub.2 NH, 1,5-diazabicyclo(4.3.0)non-5-ene and mixtures thereof, and is present in said composition in a molar ratio of metallo bleach catalyst to catalyst stabilizer of from 1:1 to 1:5,000;
• and
• C. an enzymatic system capable of generating hydrogen peroxide present in an amount capable of yielding hydrogen peroxide at a concentration of from 0.005 to 10 ppm/min in said wash solution.
