This research describes for the first time, the utilization of natural deep eutectic solvents (NADES) as green alternatives to organic solvents for improving the stability of the hormone under various storage conditions. The results showed that temperature and light effect on melatonin content during the storage presented a diverse behavior according to the solvent. At low temperatures, the hydrophilic eutectic systems based on choline chloride-glycerol and lactic acid-glucose, along with water, were the most effective in extending the shelf life of the hormone compared to conventional solvents. However, at high temperature, this behavior was reversed. Regarding the effect of light, it significantly affects the stability of melatonin, primarily UV exposure. The eutectic systems appear to be the best medium for melatonin stability under this condition.

By combining the same cation with three different α-substituted carboxylate anions, the effect of anion functional group substitution on the IL miscibility with water and hygroscopicity was experimentally evaluated and rationalized using COSMO-RS sigma profile analysis. Lower critical solution temperature (LCST) phase separation experiments and water vapor partial pressure measurements revealed that there is a stark α-substitution dependency on the affinity of water for acetate [AcO], pivalate [PivO], and trifluoroacetate [TFA] derived tributyl(octyl)phosphonium [P<sub>4448</sub>] ILs.

ILs possess unique and interesting characteristics, including excellent chemical and thermal stability and low vapor pressures. Understanding the rheological properties of ILs is essential to optimizing IL performance. This paper presents a comparative analysis of the rheological properties of two ionic liquids, N<img>Hexylpyridinium tetrafluoroborate (HPyBF4) and N<img>Hexylpyridinium bromide (HPyBr), under different shear rates, temperatures, and pressures. Rheological measurements were performed under varying controlled pressure and temperature conditions. The experimental investigation covered a pressure range of 689–12,411 kPa [100–1800 psi] and a temperature range from room temperature up to 522 kelvin (K) [480°F]. The primary objective is to explore and compare the flow behavior and viscoelastic characteristics of HPyBF4 and HPyBr under high-pressure and high-temperature conditions. The experimental data showed that HPyBF4 and HPyBr exhibited shear-thinning behavior, and pressure had an insignificant effect on rheology compared to the temperature effect. Under the same testing conditions, HPyBr showed higher shear stress and viscosity than HPyBF4.
