Abstract

Ionic liquids (ILs), often termed as "designer" solvents due to the extreme tunability of sought functional properties, are promoted by many stakeholders as green alternatives to the conventional volatile organic solvents. Nevertheless, this qualification was stated without sufficient caution versus versatility of ILs chemical structures which could induce significant variations in hazardous properties. Moreover, this class of compounds which contained organic cations and most inorganic anions may often present a high water solubility and poor biodegradability. These specific properties could influence the environmental behavior of these ILs and implied IL potential environmental and health effects. With regards to the exponential increase of applications, publications and patent for ten years, concerning ILs without halogen atoms, we may anticipate that some ILs could attain multi ton industrial production in the near future. In this context, according to the EC regulation 1907/2006 regarding REACH, each manufacturer or importer of a substance in quantity of minimum one ton by year should submit a registration application to the European Chemicals Agency (ECHA). In this context, a global view of some physico-chemical, toxicological and ecotoxicological data available in the literature, in accordance with the information requested by REACH regulation, is proposed here. In fact, it seems to be important to identify the relationship between LI structures and their (eco-)toxicological properties to help manufacturer for design of the more safe IL structures.
