Properties of sodium methyl ester alpha-aulfo alkylate/trimethylammonium bromide mixtures

The surface properties of binary mixtures of anionic sodium methyl ester α-sulfo alkylate (CmMES) and cationic alkyl trimethylammonium bromide (CⁿTAB) of different carbon chain length have been studied in the present work. The critical micelle concentration (CMC) that was obtained from the plots of...
