The Deep eutectic solvents (DES) are a class of ionic liquids that are formed by mixing a hydrogen bond donor (HBD) and a hydrogen bond acceptor (HBA) in specific molar ratios to create a eutectic mixture with a melting point lower than that of the individual components

There are several types of deep eutectic solvents depends on the hydrogen bond donor and hydrogen bond acceptor used

Choline chloride-based Deep eutectic solvents : This type of Deep eutectic solvents is formed by mixing choline chloride (HBD) with various HBA such as urea, glycerol, ethylene glycol, and lactic acid.
1) The literature viscosity, density, surface tension, and melting point of choline chloride-based DES depend on the specific HBA used.
2) For example, choline chloride-urea has a viscosity of 106.8 mPa·s, density of 1.23 g/cm3, surface tension of 50.3 mN/m, and melting point of 12.5°C.
