To best of our knowledge, we presently introduce, for the first time, the use of the residual-entropy scaling approach to adequately represent the dynamic viscosity of deep eutectic solvents (DESs) as a function of temperature and density. In this regard, various unreduced and reduced viscosity forms (total viscosity, Rosenfeld, and dilute gas) were tested and compared. The use of a cubic Equation of State (Cubic EoS: Soave-Redlich-Kwong, SRK or Peng-Robinson, PR) served here to provide sufficiently accurate residual entropy data needed by the present scalings. The resulting modeling approach was successfully validated by representing experimental dynamic viscosity data taken from the literature of three of the most representative choline chloride (ChCl) based deep eutectic solvents (DESs): ChCl:Urea(1:2), ChCl:Ethylene Glycol(1:2), and ChCl:Glycerol(1:2). The validation was conducted within a temperature range varying from 10 to 100 °C and at pressures ranging from 1 to 1,000 bar.
