The ionic liquids potentialities to organize themselves in aqueous solution and produce aggregates were analyzed through the conductivity technique and after using a new mathematical model based on stochastic theories, to indicate the linearity change moment; it was possible to analyze the presence of these aggregates. It earns interest at science of colloids and interfacial chemistry due to the recognized ability of certain surfactant ionic liquids to reduce the surface tension of aqueous solutions and to aggregate in the form of micelles, even at low concentrations, allowing their use as stabilizing or destabilizing agents in homogeneous polymerization in water/oil emulsions. Within this context, this work aims to verify the possible micellar properties of the ionic liquids. Critical micellar concentration values for ions ammonium alkyl carboxylates were obtained. It was also shown that the CMC is directly related to the lipophilic groups of the cation and entropic factors.
