Achieving Stable, Reverse Water‐in‐Fluorocarbon Emulsions

Abstract

Dispersing water in a fluorocarbon seems against nature , since two more antipathetic types of liquids, in terms of intermolecular interactions, just do not exist. Every single characteristic relevant to water‐in‐fluorocarbon reverse emulsion stability (solubility and diffusivity parameters, interfacial tension and densities) is unfavorable. Yet stable emulsions of this type can be prepared with an appropriate fluorinated surfactant. Such reverse emulsions have potential as a new class of pulmonary drug‐delivery system.
