Abstract

Ionic liquids (ILs) based on fatty acids (FAs) and choline (Ch) have been considered as promising compounds and attracted the interest of the industry and the academic community due to their unique properties, low cost and easy preparation. Their interesting properties as well as their sustainable appeal, and possibly low or non-toxicity due to the natural origin of their precursors, open new perspectives of applications in bioprocesses, in the development of bioproducts, or even in food processing. The present work is focused on three main objectives. The first is aimed at studying the synthesis of 20 ILs obtained from natural sources. The second is focused on the understanding of the thermodynamic and physical properties of ILs and their mixtures with water and vegetable oils. This step also comprises the toxicological assessment (in vivo) of ILs. The third is focused on the evaluation of the application of ILs as surfactants in the development of emulsions and in the increase of the solubility of bioactive compounds. Ch, diethanolamine, monoethanolamine, phosphoethanolamine and FAs obtained from vegetable oils, including omega 6 and omega 9 will be used for the synthesis of ILs, being novel in some cases. The melting temperatures and enthalpies, liquid crystal forming ability, critical micellar concentration, interfacial tension and rheology of ILs will be determined. Such characterization will be the base of the study of the application of ILs as surfactants in the development of W/O and/or O/W emulsions and in the increasing of the solubility of phosphoethanolamine in oily solutions. It is expected in this work the obtainment of new additives formulated by using natural compounds and bioactives with pharmacological potential, low toxicity and interesting physical properties for possible applications in the food and biopharmaceutical industries.
