ABSTRACT
If one considers the use of subzero temperature differential scanning calorimetry (SZTDSC) as an analytical tool, a striking fact becomes evident: whereas this technique has been used extensively for the study of aqueous solutions of polymers, biopolymers, and other organic compounds such as phospholipids, only a little attention has been given to the investigation of amphiphilic systems. Even less attention has been paid to the study of ternary (water+surfactant+oil) and quaternary (water+surfactant+co-surfactant+oil) systems.
