  • Fluorinated cationic surfactant
    Patent number: 8580715
    Abstract: A composition comprising a fluorinated pyridinium cationic compound of formula (I) wherein Rf is R1(CH2CH2)n—, R1 is a C7 to C20 perfluoroalkyl group interrupted by at least one catenary oxygen atom, each oxygen bonded to two carbon atoms, n is an integer of 1 to 3, and R is H, C1 to C5 linear or branched alkyl, or C1 to C5 linear or branched alkoxy, having surfactant properties for lowering surface tension in an aqueous medium or solvent medium, and for use as a foaming agent.
