Abstract
As part of an investigation into the mechanisms responsible for the formation and stability of emulsions, the partition of the homogeneous non-ionic surfactant C8H17 [O·CH2·CH2]6OH or C8E6 (E = ethoxy) in the main two-liquid (2L) regions of the three-component systems C8E6–water–dodecane, C8E6–octanol–water and the four-component system C8E6 octanol–water–dodecane has been determined. Cmc and aggregation numbers have been obtained for the surfactant in the different phase regions. The relation of these results to emulsification in the systems is discussed.
