Abstract

Aqueous dispersions of a non-aromatizable perfluorinated C.sub.9 -C.sub.18 polycyclic hydrocarbon having gas carrying properties, and a minor amount of an amidoamine oxide surfactant, the dispersions having at room temperature an average particle size of not over 0.1 micron initially and less than 0.3 micron for up to about one year or more. The ability of the dispersions to maintain low particle size over long periods at room temperature indicates exceptional stability, making them valuable as blood substitutes and therapeutic agents.
