Deep eutectic solvents (DESs) are a class of mixtures with the potential to serve as designer materials, and substitute for conventional organic solvents used in a wide variety of applications. The eutectic behavior of these mixtures has been explored in some depth, but the characteristic tendency of these materials is to behave contradictory to ideal, anticipated behavior. Therefore, experimental analyses are paramount to understanding the molecular dynamics of these materials. In this work, we have assessed a series of DESs using incremental compositions of Choline chloride (ChCl) and Ethylene glycol (EG). We have explored the rate dependence of glass phase transitions in these ChCl:EG mixtures using differential scanning calorimetry by quantifying the impacts of thermodynamic kinetics. The supporting evidence demonstrates that thermal cycling rate significantly affects glass transition temperatures, suggesting the importance of defining rate-independent transition temperatures for these mixtures.
