Wilcoxon, J P

We report measurements of the critical behavior of an inverted micelle system. The two component system consists of a nonionic surfactant n-decyl octaoxyethylene glycol monoether (C{sub 10}E{sub 8}) in a hydrocarbon, dodecane. The system has an upper critical consult point at 30 {plus minus} 2 wt % C{sub 10}E{sub 8} at a temperature of T {equals} 28.05 {plus minus} 0.03. We demonstrate both static and dynamic scaling is obeyed with universal 3D-Ising exponents describing the divergence of the osmotic compressibility and the static correlation length. 5 refs., 3 figs.
