Abstract The hydration behavior of d -glucose in aqueous solutions containing a deep eutectic solvent (DES) was studied in the temperature range: T = (293.15–313.15) K. For that, several volumetric, acoustic and viscometric properties were measured and calculated. The choline chloride + urea (1,2, molar ratio) eutectic mixture was chosen as co-solvent. The Hepler parameter and the viscosity B-coefficient showed that d -glucose in DES aqueous mixtures is a structure-making agent. Both the molar properties and the transfer properties suggested a strong solute-solvent interaction with predominance of the hydrophilic -hydrophilic contribution. Lastly, the calculated viscous flow activation parameters demonstrated high stability of the hydration structure.
