Abstract

Over the past several years there has been increased interest in the phase behavior and morphology of the dilute region of amphiphilic systems. A general sequence of phases has been shown to exist when a single variable is changed, such as alcohol, salinity or temperature of an amphiphilic surfactant solution. The surfactant can be anionic, cationic, zwitterionic or nonionic. The sequence of phase transformations represents a spontaneous change in the curvature and self — association of the amphiphile whereby an isotopic micellar solution transforms into a highly swollen homogeneous lamellar phase made up of sheets of bilayers, to an optically isotropic phase which scatters light and exhibits birefringence when sheared (1). These phases are designated L1, L α and L3 respectively.
