  • Highly concentrated self-emulsifying preparations containing organopolysiloxanes and alkylammonium compounds and use thereof in aqueous systems
    Patent number: 7629415
    Abstract: This invention concerns highly concentrated self-emulsifying preparations containing organopolysiloxanes and alkylammonium compounds and use thereof in aqueous systems on textile substrates. More particularly, this invention concerns preparations consisting of fully or partially quaternized amino-functional organopolysiloxanes, quaternary alkylammonium compounds, if appropriate an organic hydrotrope and if appropriate water.
    Type: Grant
    Filed: December 17, 2003
    Date of Patent: December 8, 2009
    Assignee: Rudolf GmbH & Co. KG Chemische Fabrik
    Inventors: Bernhard Sandner, Cristina Stanica, Longying Jiang
  • Partially quaternised, amino-functional organopolysiloxanes and their use in aqueous systems
    Patent number: 7329707
    Abstract: This invention concerns preparations containing partially quarternized amino-functional organopolysiloxanes and use thereof in aqueous systems on textile substrates. The preparations contain (1) 2 to 60 percent by weight of a partially quartenized amino-functional organopolysiloxane, (2) 2 to 40 percent by weight of an emulsifier, (3) 0 to 15 percent of a hydrotrope and (4) 20 to 95 percent by weight of water, with the proviso that the total nitrogen content of component (1) is in the range from 0.05 to 2.0 percent by weight, based on the overall composition of component (1).
