“…The cmc for pure C12BzCl obtained both by conductivity and surface tension measurements are in agreement with each other and with the literature values. 17,25,26 Table 1 lists the cmc values of C12BzCl in the presence of different concentrations of various Tweens as studied by conductivity and surface tension measurements. The cmc values of C12BzCl show a regular decrease with increase in the concentration of all kinds of Tweens.…”

“…Owing to its ability to form stable water-in-oil microemulsions and capacity of micellar solubilization in binary surfactant systems, C12BzCl has been the subject of intense investigations. A. Amin et al 17 have studied the effect of sodium alkanoates on the micellization of C12BzCl in aqueous medium using conductometric and fluorescence quenching experiments and the results show that the variation in the cmc of C12BzCl is due to the combined effect of salt effect, solubilization, chain length compatibility, and the solvent modifying tendency of the carboxylate salts. T. Farias et al 18 have studied the solubilization of drugs by benzalkonium chloride micelles using conductivity and 1 H NMR experiments.…”

The present work is aimed at studying the interactions between mixed micelles of nonionic surfactants, Tweens (Tween 20, Tween 40, Tween 60, and Tween 80) and cationic surfactant, dodecylbenzyldimethylammonium chloride (C12BzCl), and to draw a comparison between the effect of different Tweens with respect to fatty acid chain present in them. Both from the industrial and research point of view, the present day need for newer materials has been diverted to surfactant-additive systems rather than single surfactant systems because of the great fundamental, technological, and biological importance associated with the mixed micelles. Moreover, Tweens being biocompatible, stable, and relatively nontoxic can be used to enhance the efficacy of benzalkonium (Bz)-based disinfection products. Conductivity and surface tension techniques have been employed to determine various micellar parameters like critical micellar concentration (cmc), degree of counterion binding (β), standard free energy of micellization (ΔG mic o ), excess free energy of mixing (ΔG ex o ), interaction parameter (β m ) and activity coefficients for the Tweens (f 1 ) and C12BzCl (f 2 ) in the mixed micelles using Rubingh's, Motomura's, and Maeda's approach. The negative values of β m indicate synergism in the mixtures which is highly beneficial as it reduces the total amount of surfactant used in a particular application resulting in reduction of cost and environmental impact. The results have also been discussed in terms of short-range interactions between the two types of surfactants.
