The aim of this study was to investigate acute and subacute oral toxicity of an ionic liquid, didecyldimethyl-ammonium acesulfamate [DDA][Ace], in rats. The compound tested was classified to the fourth toxicity class with a fixed LD50 cut-off value of 500 mg/kg. Organ pathology induced by [DDA][Ace] in acute experiments included exfoliation of the surface layer of the digestive tract and alveolar septa in lung parenchyma. In a subacute experiment, rats were administered 10, 50, and 100 mg/kg/day [DDA][Ace] for 28 days. Reduced body weight gain and reduced food consumption was observed in mid-and high-dose rats. Statistically significant hematology changes were found mostly in high-dose groups of both sexes: increases in hematocrit, mean corpuscular volume, and mean platelet volume. Statistically significant changes in clinical chemistry parameters included increases in the GGT, SDH, and LDH activity and bilirubin concentration, and decreases in triglycerides, glucose, and inorganic phosphorus concentration. No treatment-related microscopic changes were observed. Under the conditions of this study, the lowest-observed-adverse-effect level of [DDA][Ace] was considered to be 10 mg/kg/day.
