The present invention relates to the use of selected metal complex compounds and ligands as oxidation catalysts as well as to a process for removing stains and soil on textiles and hard surfaces. The metal complex compounds have hydrazide ligands, preferably with electron withdrawing groups in the phenyl ring adjacent to the acyl group. Further aspects of the invention are formulations comprising such metal complex compounds, novel metal complex compounds and novel ligands.

Use of metal hydrazide complex compounds as oxidation catalysts

The present invention relates to the use of metal complex compounds with terpyridine ligands as oxidation catalysts. The present invention relates also to formulations comprising such metal complex compounds, to novel metal complex compounds, and to novel ligands. The metal complex compounds are used especially tor improving the action of peroxides, for example in the treatment of textile material, without at the same time causing any appreciable damage to fibres and dyeings.

Use of metal complex compounds as oxidation catalysts

The present invention relates to the use of metal complex compounds having hydrazide ligands as oxidation catalysts. Further aspects of the invention are formulations comprising such metal complex compounds, novel metal complex compounds and novel ligands. The metal complex compounds are used especially for enhancing the action of peroxides, for example in the treatment of textile material, without at the same time causing any appreciable damage to fibers and dyeings. There is also no appreciable damage to fibers and dyeings if these metal complexes are used in combination with an enzyme or a mixture of enzymes.
