Abstract
It is well known that the amoutn of water that can be incorporated in AOT reversed micelles is dependent on its salinity [1] and on the nature of the electrolyte [2]. A maximum of solubility exists, which has been shown by Shah et al. [1] to result from two distinct behaviors of the surfactant film, depending on whether it is attractive (case of low salt concentration where the phase behavior is governed by a critical droplet radius Rc) or not (case of high salt concentration, where the phase behavior is governed by the spontaneous radius of curvature Ro). Biphasic systems separating with an excess water phase (the so-called Winsor II systems) can only be the presence of a specific electrolyte depending on its concentration is not fully understood.
