Abstract

Oil in water microemulsions were prepared using didodecyldiphenylether disulfonate gemini-type surfactant (C12-DADS), water, oil (toluene) and a co-solvent (short chain alcohol such as 1-propanol). The phase diagrams for microemulsions with gemini surfactants were determined and compared to those of structurally related surfactants, monododecyldiphenylether disulfonate (C12-MADS) and monododecyldiphenylether monosulfonate (C12-MAMS). Conductivity measurements and direct imaging by cryo-TEM were performed to characterize the phases.
