Phase diagrams. Pseudo-ternary phase diagrams obtained at 25°C for the systems: (A) CTAB + CTAFeII/n-butanol/n-hexane/water, (B) CTAB + CTAFeII/alcohol/n-hexane/water, and (C) surfactant/n-butanol/n-hexane/water. The section closed within the solid (or dashed) lines corresponds to the microemulsion phase. The discontinued lines in (A) represent the H values used for the measurements. Symbols indicate the compositions for the SANS measurements.
