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.
