Structure of mixed anionic/nonionic surfactant micelles: Experimental observations relating to the role of headgroup electrostatic and steric effects and the effects of added electrolyte
Article Abstract:
The roles of the headgroup steric and electrostatic contributions to the free energy of micellization are studied. Small angle neutron scattering (SANS) is used to investigate the mixed surfactant micelles of sodium dodecyl sulfate (SDS)/C12E6 and SDS/C12E8 in D2O and in weak electrolyte.

Structure and composition of mixed surfactant micelles of sodium dodecyl sulfate and hexaethylene glycol monododecyl ether and of hexadecyltrimethylammonium bromide and hexaethylene glycol monododecyl ether
Article Abstract:
The geometry and composition of mixed surfactant micelles of sodium dodecyl sulfate (SDS) and hexaethylene glycol monododecyl ether (C12EO6) and of hexadecyltrimethylammonium bromide (C16TAB) and C12EO6 were examined using small-angle neutron scattering. SDS/C12EO6 system was found to mix nonideally and has a compositional data that are concordant with regular solution theory. In contrast, the C16TAB/C12EO6 system ideally mixes and its growth was found to increase with increasing surfactant concentration and mole function of C12EO6 in solution.
