  • Cleaning Agent Comprising Complexes with Bleach Catalytic Activity
    Publication number: 20090042764
    Abstract: Hard surface cleaning agents comprising a macrocyclic compound of the general formula L: wherein each of n1, n2 and n3 independently represents 1 or 2; and hard surface cleaning agents comprising a transition metal complex of the general formula (I): [MLaXb]cY??(1) wherein M represents a metal selected from the group consisting of manganese, iron, cobalt, copper, ruthenium, molybdenum, and combinations thereof; X represent a neutral or anionic ligand; Y represents a non-complex-bound anion; a represents 1 or 2; each of b and c independently represents a number of 0 to 6, with the proviso that b and c are selected such that the complex is neutral based on M, X and Y; and L represents a macrocyclic ligand of the general formula L; and methods of cleaning hard surfaces therewith.

  • Support-fixed bleaching catalyst complex compounds suitable as catalysts for peroxygen compounds
    Patent number: 7335629
    Abstract: The present invention relates to support-fixed bleaching catalyst(s)suitable or the catalysis of peroxide compounds, characterized in that the support-fixed bleaching catalyst(s) is/are covalently bonded to a support by means of at least one organic ligand of the bleaching catalyst. The bleaching catalyst(s) form(s) a complex with at least on transition metal. The invention further relates to support-fixed bleaching catalysts for the catalysis of peroxide compounds, where at least one ligand, covalently bonded to a support, is a transition-metal-free ligand, which chelates with transition metal, derived from another source, preferably from the bleaching composition and/or added water and thus forms the complex with a transition metal.
