  • Publication number: 20020090349
    Abstract: Process for the biocidal treatment of surfaces, by applying an aqueous biocidal composition containing a biocidal agent (B), a surfactant (SA) when the said biocide is hydrophobic, and at least one water-soluble or water-dispersible organic copolymer (C) comprising at least one oligomeric or macromolecular unit (D) which can interact with the said biocide or with the micelles of surfactant(s) containing the said biocide when it is hydrophobic, and at least one hydrophilic macromolecular unit (E) which can interact with the surface to be treated and optionally with the said biocide. Use of the copolymer (C) in a biocidal composition for the treatment of surfaces, as an agent for the vectorization and/or controlled release of the said biocide onto the surface to be treated.

  • Patent number: 6379394
    Abstract: A soil-repellent treatment method for articles based on woven cotton, wherein an amphiphilic soil-repellent agent soluble or dispersible in the treatment medium is deposited on the article during one or more washing, rinsing and/or softening or dying steps, is disclosed. Said soil-repellent agent comprises at least one unit with a function (FAd) capable of being absorbed onto the surface of the cotton by electrostatic interaction; and at least one hydrophobic unit (MH) capayble of configuring said agent at the cotton/water interface. A soil-repellent agent comprising at least one unit with a cationic function (MC) capable of being absorbed onto the surface of the cotton, and the counter-ion thereof, as well as at least one hydrophobic unit (MH) containing at least four carbon atom chemically bonded to the unit having said cationic function (MC) via an oligomeric, polymeric or copolymeric vinyl alcohol chain, is also disclosed.
