Abstract The critical micelle concentrations (CMC) of cetylpyridinium chloride (CPC) in water/glycerol media and the presence sodium were determined at 25 °C by surface tension conductance methods. Variation CMC follows normal trend, i.e., it increases with glycerol content decreases on adding NaCl. Empirical analysis exponential increase CPC weight per cent is indicative having two components; one component being dependent while other independent amount. counter ion binding constant was from both slope–ratio Corrin‐Harkins methods showed no dependence amount, thus confirming unusual trend behavior β media. In a medium, ratio solvent to limiting also whereas Gordon Parameter increasing as aqueous organic solvents. air–solution interface becomes saturated adsorption when concentration added NaCl about 0.02 mol kg −1 irrespective
