✦ Synopsis

Two-phase systems consisting of water-in-oil (W/O) microemulsions in equilibrium with excess water and oil-in-water (O/W) microemulsions in equilibrium with excess oil have been prepared using the surfactant sodium bis( 2-ethylhexyl)sulphosuccinate (AOT) without cosurfactant. The interfacial tension of the planar interface separating the phases for the W/O case is only weakly dependent upon the volume fraction ofdroplets in the microemulsion phase whereas for the O/W case, the microemulsion droplet size increases and the tension drops as the dispersed volume fraction is increased.
