The ternary system of surfactant/water/nonpolar solvent forms an aggregate called a W/O microemulsion. 1~ 2 When the system contains small amounts of water (eg,[water]/[surfactant]< lo), the aggregate is termed a reversed micelle. In a reversed micelle, a water droplet of 10-50 A in diameter is surrounded by the monolayer of surfactant molecules with their polar heads toward the water phase Stimulated by its similarity to the ...
