Abstract
Time- and temperature-dependence of the small angle X-ray scattering (SAXS) profiles for homogeneous and transparent solutions of the sodium dioleylsulfosuccinate (SDOleS)–decane–water system with various molar ratios of [H2O]/[SDOleS] have been examined. The time-dependence of the SAXS profiles has provided evidence that the droplet–lamellar transition occurs spontaneously but very slowly at 298 K. This behavior depends upon the quantity of water solubilized into the SDOleS microemulsions. Some microstructural models have been proposed to explain this very slow transition.
