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.
