Abstract

Abstract: This study describes the enhancement in the solubility and controlled‐release of fragrance agents (menthol, four n ‐alkanols, and three aromatic esters) using three CO2 switchable surfactants ( N ‐alkylimidazolium bicarbonates). The surfactants significantly improved the solubility of fragrance agents in water. N ‐Dodecylimidazolium bicarbonate was the most effective surfactant to solubilize menthol. A stability test indicated that the surfactant could stably disperse menthol in water. Moreover, the surfactants improved the solubility of n ‐alkanols to different levels, however, the solubility of the aromatic esters equally. The release of menthol from the surfactant solution under N2 at different durations of bubbling time, temperatures, and flow velocities were studied.
