Abstract:

The surface properties and micellar behaviors of mixed systems composed of dodecylammonium chloride (DAC) and sodium alcohol ether sulphate (AES) have been studied in great detail. The results of this study revealed that the mixed systems possessed excellent surface activities over a wide range of molar ratios and temperature intervals. Variations in the critical micelle concentrations (cmc) and corresponding surface tension (γcmc) of the mixtures were determined over a range of molar ratios and temperatures, and several environmental factors were also evaluated, such as pH and ionic strength.

Key words: Cationic and anionic surfactant mixed system, Solubility, Ultra-low interfacial tension, Surface property
