Microemulsion systems with their inner structure in the colloidal domain have been the subject of many theoretical and experimental studies due to their very broad applicability [1-4]. The name “microemulsion” was fi rst introduced by Hoar and Schulman in 1943 as the name for a clear or transparent system obtained by titration of a milky white emulsion with a medium-chain length alcohol (e.g., 1-pentanol or 1-hexanol) [5]. A more general defi nition of the term “microemulsion” was given later by Danielsson and Lindman, who described it as a “system, composed of water, oil and an amphiphilic component, being an optically isotropic and thermodynamically stable liquid solution” [6].
