  • Patent number: 7429558
    Abstract: The invention relates to a fabric treatment composition which comprises a self-crosslinking polymer possessing pendant azetidinium groups. A first aspect of the invention comprises an azetidinium functionalized polymer containing primary or secondary amine groups. Cross-linking reactions between the azetidinium group and primary or secondary amine groups do not form quaternary groups and consequently do not result in a charged, cross-linked polymer. This lack of charge is believed to overcome the problems of stain fixing and dye adsorption. A second aspect of the present invention subsists in an azetidinium functionalized polymer of which the monomers comprise: an amino-acrylate and/or amino-alkacrylate monomer, and, optionally, further non-amino acrylate and/or alkacrylate monomer.

  • Patent number: 7012055
    Abstract: Fabric treatment compositions comprising a textile compatible carrier and particles having a layered structure comprising oxygen atoms and silicon and/or phosphorus atoms and comprising organic functional groups which are bonded to silicon and/or phosphorus atoms by direct covalent bonds between the silicon and/or phosphorus atoms and a carbon atom. The functional groups are selected to impart lubricating properties to the particles.
