Com. available tech. grade non-ionic surfactants usually contain impurities and have a broad distribution of mol. weight owing to degree of ethoxylation. It has shown that the surface tension method (Wilhelmy plate) is very sensitive if impurities are present in the surfactant. Much lower CMC values are obtained for tech. grade surfactants with the surface tension method than with the dye solubilization method. The CMC determined by the dye solubilization technique are in fair agreement with the values obtained by other available methods. The change in CMC of Tween-40 has been studied through the influence of additive Chloramine-T in aqueous medium by measuring the absorbance of the pure surfactant and with Chloramine-T in presence of the water-insoluble dye Orange-OT by using the dye solubilization technique. The absorbance was increased with increasing concentration of pure Tween-40. The absorbance of the mixed systems with Chloramine-T shows the same trend. The CMC of pure surfactant was decreased with increasing concentration of Chloramine-T. The influence of Chloramine-T on the absorbance of Tween-40 is a clear indication that the phenomenon of dye micellization is associated with the different micelles coalescing.
