Natural deep eutetic solvents (NADES) are defined as a mixture of two or more solid or liquid components, which at a particular composition present a high melting point depression becoming liquids at room temperature. NADES are constituted by natural molecules and fully represent the green chemistry principles. For these reasons, the authors believe that the submit manuscript is a highly valuable contribution to the field of green chemistry and chemical engineering. For the first  time, the possibility to use NADES as enhancers of supercritical fluid tecnology is revealed.
