Microemulsion Phase in Equilibrium with Birefringent Surfactant-Rich Phasest, as well as salt (usually) and alcohol (often). Phase behavior of a commercial surfactant has been studied as a function of salinity, surfactant concentration, and temperature. The number of phases depends in a systematic way on the above factors. As surfactant concentration increases or temperatu

Critical Behavior in a Microemulsion System: I — Experimental Evidence for Field Like Variable apparent field variable related to composition: the water over surfactant ratio. In polyphasic regions this variable (denoted X in the following) has the same value in the different phases in equilibrium. For a quaternary mixture we report results concerning a three-phase equilibrium which involves

The critical points were approached either by raising the temperature at fixed composition (path I) or by increasing the water over surfactant ratio (denoted X) at constant temperature (path II). For each critical point investigated, the critical exponents V and . associ

Experiments on the dilute microemulsion show that the droplet structure is retained as the critical region is crossed and that the critical scattering arise

Analysis of Sans Data from Dense Microemulsionsattering (SANS) technique. Each intensity spectrum exhibits a clear diffraction maximum. As the surfactant volume fraction Ψ. increases, the peak position moves to higher values of Q, while the peak height diminishes. Attempts were made to interpret the intensity spectra using the following models:

Investigation of the Microemulsion Phase Structure of Polyphasic Systems by Time Domain Spectroscopyring. Time domain spectroscopy reveals that this structure could be that of concentrated oil-in-water dispersions of microdroplets ? on a wide range of surfactant concentrations. Light scattering shows that the radii of the microdroplets would be between 150 and 250 ? ? and that their interactions c
