NMR Diffusion and Relaxation Studies on Surfactant Systems

Abstract

The unique bilateral structure of surfactants allows for a variety of interesting applications in society and industry. In this study, we focused on one particular non-ionic surfactant referred to as C10E7P2OH. Six solutions were analyzed by DOSY, T1 and T2 experiments in order to determine the structure and size of the aggregates formed in solution. Three of these solutions contain the surfactant C10E7P2OH in water at concentrations by mass of 2, 3.5 and 5%. Three solutions contain surfactant at identical concentrations, and also D-limonene at 2% by mass.
