  • Patent number: 7928049
    Abstract: 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.

  • Patent number: 7659354
    Abstract: The present invention is directed to polymeric compounds comprising a main backbone derived from at least the following monomeric components: (I) 20 to 99.9% by weight, preferably 50% to 99% by weight, of at least one cationic monomer according to formula (I), and (II) 0.1 to 80% by weight of a hydrophobic unsaturated nonionic monomer that polymerizes in the presence of an initiator, optionally a water-soluble monomer (III) different from either monomer (I) and monomer (II), and optionally a crosslinking agent (IV). Said compounds are particularly useful to overcome the problem of dye bleeding and/or dye transfer in laundry processes.
