Solubilization and release of fragrance agents in the aqueous solution of CO 2 switchable surfactants

This study describes the enhancement in the solubility and controlled‐release of fragrance agents (menthol, four n ‐alkanols, and three aromatic esters) using three CO 2 switchable surfactants ( N ‐alkylimidazolium bicarbonates).

Description
Summary:This study describes the enhancement in the solubility and controlled‐release of fragrance agents (menthol, four n ‐alkanols, and three aromatic esters) using three CO 2 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 N 2 at different durations of bubbling time, temperatures, and flow velocities were studied.
