The conductivity measurement were performed on aqueous solutions of 1-decyl-3-methylimidazolium bromide ([C10mim]Br) in the absence and presence of carbohydrates at different temperatures. The values of the critical micelle concentration (cmc) were obtained and it was found that all the investigated carbohydrates have salting-out effect on the aggregation of [C10mim]Br in aqueous solutions, leading to significant downward shifts of the cmc.
