Fundamental studies have improved understanding of molecular-level properties and behavior in surfactant-oil-water (SOW) systems at equilibrium under nonequilibrium conditions. However, confusion persists regarding the terms "microemulsion" "curvature" these systems. Microemulsion refers to a single-phase system that does not contain distinct oil or water droplets but least four different structures with globular domains nanometer size sometimes arbitrary shape. The significance such is unclear. At high surfactant concentrations (typically 30 wt % more), single phase zone has been identified which complex molecular arrangements may result light scattering. As concentration decreases, referred as bicontinuous microemulsion, known middle Winsor III triphasic system. Its structure described involving simple multiple films surrounding more less elongated excess globules. In cases where separates into two three phases, I II systems, one containing most surfactant, also confusedly microemulsion. this surfactant-rich phase, only curved objects are micellar soluble no real interface rather exchange molecules external liquid an ultrafast pace. use term context microemulsion confusing, particularly when applied merged nanometer-size percolating domains. work, we discuss "curvature", four-dimensional spatiotemporal model proposed concerning SOW equilibrated near optimum formulation.
