Mixed surfactants: Sodium bis (2-ethyl-hexyl) sulphosuccinate-didodecyldimethyl-ammonium bromide-water system Academic Article uri icon


  • Phase equilibria for the mixed surfactant system didodecyl-dimethylammonium bromide (DDAB)-Sodium di-(2-ethylhexyl) sulphosuccinate (AOT)-water are studied by 2 H NMR, optical-and cryo-transmission electron microscopy methods at 303 K. The phase behavior displayed by the mixed system as well as the stability region of various single phases are discussed in terms of surfactant molecular packing considerations and electrostatic effects.
