Table 1 The properties measured for the ILs: the EC50 values were determined using Vibrio Fischeri bacteria with 5 min and 15 min incubation; the concentration range within which the phase transition was no longer detected (Loss of transition); the critical micelle concentration (CMC) and the fitting method used for the CMC determination (superscript).
