Cleavable surfactants are amphiphiles in which a weak linkage has been deliberately inserted, normally, but not always, between the hydrophobic tail and the polar headgroup. The main objective behind the development of cleavable surfactants is to improve the rate of biodegradation and the rate of biodegradation has been studied for several of the surfactants [۲]. pH labile linkages in surfactants result in special applications in industry and biological science such as targeting drug delivery, gene therapy and … [۳]. The viscosity of surfactant is greatly related to the size, shape and organization of micelles in solution [۴]. In this article aggregation behavior of ester-containing gemini surfactant 'dodecyl betainate gemini (s=۳)' which is new synthesized surfactant was investigated using viscosimetry and dynamic light scattering.
