Several studies engaged in understanding the behavior of aqueous mixtures of deep
eutectic solvents have recently emerged. A transition from one system to another
upon the addition of water is proposed by several studies. A deeper understanding
of deep eutectic solvents still requires further studies especially that there are a
countless number of combinations that can lead to their formation.
