Are Ionic Liquids toxic?
There is no general answer to this question. Since Ionic Liquids can consist of many chemically different types of cations and anions this question has to be answered case by case. The “magic Ionic Liquid” which meets all requirements in toxicity, ecotoxicity, stability and performance simply does not exist. Up to now there is still very limited information available regarding a full toxicological profile of Ionic Liquids. Only recently some valuable data has been published [14]. This data was collected for the notification process of the corresponding Ionic Liquids and represents examples from the most common classes of cations: EMIM, BMIM and ammonium.
