Optimal estimation techniques were developed for measurement of interfacial tensions and contact angles for multiphase microemulsion systems of the following types: (1) lower-phase microemulsion in equilibrium with excess oil, (2) upper-phase microemulsion in equilbrium with excess brine, and (3) middle-phase microemulsion in equilibrium with excess brine and excess oil. The surfactant was the monoethanol amine salt of dodecyl o-xylene sulfonate mixed with a cosolvent of t-amyl alcohol in the ratio 63/67 by vol. The oil was a mixture of 90% paraffinic oil (Isopar M) and 10% heavy aromatic naphtha (by volume), and the brine was various concentrations of NaCl in distilled water. The method is applied to sessile drops, bubbles, and pendant configurations. 21 referernces.
