The formation of a water‐in‐oil (w/o) microemulsion in Triton X‐100/1‐butanol/alkane/water systems was investigated at 25.0±0.1°C. Phase inversion temperatures in hydrocarbon‐water microemulsions stabilized with Triton X‐100 were determined for different hydrocarbons. It was found that the more soluble the alkane (oil), functioning as a nonionic emulsifier, the lower was the phase inversion temperature, above which oil‐in‐water type microemulsions invert to w/o type. The effect of the presence of cosurfactant was studied. No phase inversion was observed in the absence of cosurfactant. The effect on phase inversion temperature of decreasing or increasing the temperature was evaluated. By definition, phase inversion was not affected by different temperatures.
