Abstract
Increased stability is conferred on oil-in-water emulsions of perfluorocarbons by addition of a minor (0.1-5% w/v) amount of a fluorinated compound of higher boiling point than the perfluorocarbon being emulsified. The added fluorinated compound is preferably a perfluorinated saturated polycyclic hydrocarbon. The most preferred additive is perfluoroperhydrofluoranthene.
