On the other hand, research have been performed using CnSA for studies of adhesion interactions [10] and a saturated derivative of C18SA was used in nucleation and control ofthe inorganic crystal growth in Langmuir experiments [11,12]. Since a key feature of CnSA is their ability to undergo selfassembly in water, a process in which factors such as surfactant molecular structure, surfactant concentration, and temperature dictate the type of aggregates formed; the aim of this work was to describe the aggregation behavior of disodium salt of 2-(2-decenyl) succinic acid C10SA (n = 10, Scheme 1) in alkaline aqueous media. The understanding of the physical chemical mechanism of aggregation and particularly the structural factors responsible for its surfactant efficiency despite its relatively short hydrophobic tail and a big hydrophilic head, will be important for the design of new materials.
