Abstract

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.
