  • Compositions and methods for emulsifying a pefluorocarbon with an oxygen-carrying surfactant
    Publication number: 20070026024
    Abstract: A physiologically acceptable perfluorocarbon emulsion composition that includes perfluorodecalin and an oxygen-carrying fluorinated surfactant forming a stable emulsion in a continuous aqueous phase. The oxygen-carrying fluorinated surfactant may be fractionated to increase its physiological compatibility, and may further include a fatty acid radical perfluorinated to increase its oxygen-carrying capacity. The perfluorocarbon emulsion composition of the present invention thus exhibits improved stability and efficiency, broadening its application and effectiveness as an artificial oxygen carrier.
