Abstract
Publisher Summary The term “Solubilization” denotes the increased solubility of a given compound, associated with the presence of surfactant micelles or inverted micelles in the solution. The most popular solubilization process is the transfer of oil molecules into the core of surfactant micelles. Thus, oil that has no solubility in the aqueous phase becomes water-soluble in the form of solubilizate inside the micelles. This process has a central importance for washing of oily deposits from solid surfaces and porous media, and for removal of oily contaminants dispersed in water. The main actors in the solubilization process are the micelles of surfactant and/or copolymer. Their ability to uptake oil is of crucial importance. The addition of copolymers, which form mixed micelles with the surfactants, is a way to control and improve micelle solubilization performance. This chapter presents the models of solubilization kinetics, which have been verified for surfactant/polymer systems and discusses the specific role of the copolymers as promoters of oil solubilization in the surfactant systems.
