Use of Metal Complexes Having Bispyridylpyrimidine or Bispyridyltriazine Ligands as Catalysts for Reactions With Peroxy Compounds for Bleaching Coloured Stains on Hard Surfaces

摘要

The present invention relates to the use of certain manganese complexes having bispyridylpyrimidine or bispyridyltriazine ligands or mixtures of such ligands as catalysts for reactions with peroxy compounds for bleaching coloured stains on hard surfaces, especially dishes in automatic dishwashers. The invention relates also to cleaning formulations for hard surfaces comprising such catalysts.
