Mixed micellization and interfacial properties of alkanediyl-α, ω-bis(dimethylcetylammonium bromide) in the presence of alcohols

► Interactions of the cationic gemini surfactants 16-s-16 (s = 4,5,6) and linear alcohols have been investigated at 303 K. ► Mixed micellization is observed in each case. ► Nagg and micropolarity of the systems were evaluated using fluorescence measurements.
