Interaction and Viscous Properties of Aqueous Solutions of Mixed Cationic and Nonionic Surfactants

“…. [7] indicates that the ionic head group not only interacts with the oxyethylene groups nearer to the hydrocarbon chain but also with the oxyethylene groups remote from the hydrocarThis variation in b values can also be explained by considbon chain. This is further confirmed by the fact that the ering cationic-cationic repulsion at a higher mole fraction principal peak of the multiplets remains at the same position of CTAB and the cationic head group-oxonium ion repuleven in the mixed binary systems, indicating the peak of sion as a secondary effect, as described in case of the NP oxyethylene groups which are not taking part in the interacseries.…”

Adsorption Behavior of Cationic and Nonionic Surfactant Mixtures at the Alumina–Water Interface

“…The regular solution model was used to fit these, and an interaction parameter (b) between 01.5 and 01.2 was obtained. A considerable number of binary mixed micellar systems have been studied using this procedure (4)(5)(6)(7)(8) and the inter- anionic systems (4), 04.6 to 01.0 (16,17) for anionic-quantity of NP-15. If the relative and absolute quantity of NP-15 is lower, synergism between these two surfactants is seen.…”

Mixed Surfactant Systems

“…This was based on the pseudophase separation approach with the assumption of ideal mixing in the micelles. Generally, ideal mixing models have been successful in describing the CMC behavior of binary ionic (28,39,41*42) and binary nonionic (22,91,92) surfactant mixtures, especially for surfactants with the same hydrophilic group. Clint has extended the ideal binary mixing model to explicitly treat surfactant monomer concentrations and micelle compositions (91).…”
