The neighborhood of the three-phase regime in microemulsions

We extend a previous calculation and comparison with experiment of the shape of the three-phase regime, of a ternary mixture of water, oil, and tenside, in the space of concentrations and temperature x, y, τ into the neighborhood of the three-phase regime. Apart from the two- and one-phase boundaries, we determine the behavior of the intensity of scattered light and the interfacial energies. The agreement with experimental data is reasonable.
