Abstract
Supercritical CO 2 is considered as a promising alternative for volatile organic solvents currently used in certain industrial processes and products, however, the poor solubilizing power of CO 2 towards polar substances remains a significant barrier to applications. Employing effective surfactants which generate stable dispersions and water/CO 2 microemulsions is accepted as one way to improve the physico-chemical properties of CO 2. This article reviews recent studies on microemulsions in liquid CO 2, as well as the development of CO 2-philic surfactants.
