In this article, we report the results of the mixing behavior of alkanediyl-alpha,omega-bis(dimethylcetylammonium bromide) gemini surfactants with anionic hydrotropes (sodium salicyalte, sodium benzoate, and sodium tosylatc) in aqueous solutions using conductivity measurements. The critical micelle concentration (cmc) for different mixing mole fractions at different temperatures, their ideal cmc values, and different interaction parameters have been estimated. The results show that the mixing behavior is nonideal and the interactions among the surfactants and the hydrotropes are synergistic in nature.
