AB  - The ability of Room Temperature Ionic Liquids (RTILs) to support the self-aggregation of amphiphilic
molecules such as non-ionic surfactants have enhanced their applications in the industry. The aim of the
present study is to formulate and investigate the properties of surfactant/RTILs and surfactant/RTILs/oil
aggregation intended for separation processes. The aggregation behaviour of a non-ionic surfactant,
Tween80 in 1-butyl-3-methylimidazolium hexafluorophosphate (bmimPF<sub>6</sub>) and 1-butyl-3-methylimidazolium
tetrafluoroborate (bmimBF<sub>4</sub>) was determined by measuring the surface tension of surfactant/RTILs mixture at
different concentration ratios. The resulting Critical Micelle Concentrations (CMCs) were compared with the
ones in the water. The CMCs of Tween80 in bmimPF<sub>6</sub> and in bmimBF<sub>4</sub> were found to be much higher than that
in water under the same condition. The relatively low solvophobicity between RTILs and the hydrophobic tail
of Tween80 led to increased CMCs. The aggregation behaviour of Tween80 in RTILs was further investigated
in the presence of an oil phase. The added Palm Oil Ester (POEs) induced the formation of oil-in-RTIL
nanoemulsions. These nanoemulsions were prepared using low energy method and were characterized using
Zetasizer measurement and transmission electron microscopy. The particle size of Tween80/bmimBF<sub>4</sub> / POE were found comparable to the ones in water. The results showed that the introduction of oil phase produced a
diverse effect towards hydrophobic and hydrophilic RTILs.
