Based on the observations made so far, we can safely state that if the organic phase becomes enriched with surfactant, inverted (i.e., water-in-oil) emulsions can form provided that the organic phase contains water as well. This is an important issue, as the particular system that we are interested to resolve is that of an aqueous phase with surfactant contacting an organic phase without the surfactant. One expects that inverted emulsions would form in the organic phase provided both the surfactant and water diffuse into it from the underneath aqueous phase. This issue was addressed previously by Davies, J. T.; Wiggill . This issue is also relate to a recent interesting study by Yang and Abbott , who reported the growth of water droplets on a hydrophobic surface immersed in water, where water vapor had to pass through a layer of oil following which it could undergo nucleation and growth on the hydrophobic substrate. Hence, there already exists evidence that water can dissolve in, and diffuse through, oil. If such is the case, the results summarized in Figure suggest that inverted emulsion would form in that phase in the presence of surfactant. Enrichment of an organic phase by a surfactant due to diffusion from the aqueous phase is directly detectable in UV spectroscopy (see below). The issue regarding water diffusion is addressed next.
