Analysis of the asymmetric synergy in the adsorption of zwitterionic–ionic surfactant mixtures at the air–water interface below and above the critical micelle concentration

Abstract:

Surface tension (ST) and neutron reflection (NR) measurements have been made on a series of mixtures of two ionic surfactants, one anionic (SDS) and one cationic (C12TAB), with the two zwitterionic surfactants dodecyldimethylammonium propanesulfonate (C12SB) and dodecyldimethylammonium acetate C12CB. The anionic surfactant SDS interacts equally strongly with both zwitterionics and the C12TAB less strongly. For the SDS–C12SB mixtures simultaneous fitting of ST and NR data made it possible to u...
