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