Drop profile analysis tensiometry is applied to determine the distribution coefficient of a nonionic surfactant for a water/hexane system. The basic idea is to measure the interfacial tension isotherm in two configurations: a hexane drop immersed in the surfactant aqueous solutions at different bulk concentrations, and a water drop immersed into a hexane solution of the same surfactant. Both types of experiments lead to an isotherm for the equilibrium interfacial tensions with the same slope but with a concentration shift between them. This shift refers exactly to the value of the distribution coefficient.

Emulsion stability simulations of nondeformable and deformable droplets are used to justify the change in the number of aggregates as a function of time shown by (decane ? CCl 4 )/water emulsions stabilized with either sodium di-octyl-sulfosuccinate (DOSS) or sodium oleate (NaOl). It is found that the results of the simulations depend sensitively on the value of the bending modulus B 0 of the surfactant monolayer. The experimental data of DOSS and NaOl emulsions can only be accurately reproduced by assuming the occurrence of deformable droplets in both cases, along with a significant variation of B 0 as a function of the salt concentration [NaCl]. Otherwise only reasonable agreement is found. In the second scenario, the rates predicted by the simulations of nondeformable droplets are closer to the experimental values of the emulsions stabilized with [NaOl] = 0.5 mM, [NaOl] = 1.0 mM, and [DOSS] = 0.42 mM. Conversely, the rates predicted by the simulations of deformable droplets are closer to the experimental data of the system containing [NaOl] = 2.0 mM.
