“…Although sugar-based surfactants are now very extensively examined, studies are mainly focused on methods of synthesis, aggregation behavior [28][29][30], creation of organogels [31,32], emulsion/microemulsion characterization [33,34], and mixture behavior [35,36]. Only a few papers deal with adsorption behavior [37][38][39][40][41].…”

“…The larger β σ and β m values for the AEO 9 /SDS mixture than those for the AEO 9 /CTAB mixture indicate attractive interaction in the AEO 9 /SDS mixture larger than that in the AEO 9 /CTAB mixture. For the mixed system, if there is no interaction between the two components composing the mixed adsorption film, the ideal molecular cross-sectional area of the mixed adsorption film can be calculated by the following equation (Rosen and Sulthana, 2001)…”

Abstract:The interaction in two mixtures of a nonionic surfactant AEO 9 (C 12 H 25 O(CH 2 CH 2 O) 9 H) and different ionic surfactants was investigated. The two mixtures were AEO 9 /sodium dodecyl sulfate (SDS) and AEO 9 /cetyltrimethylammonium bromide (CTAB) at molar fraction of AEO 9 , 9 AEO =0.5. αThe surface properties of the surfactants, critical micelle concentration (CMC), effectiveness of surface tension reduction (γ CMC ), maximum surface excess concentration (Γ max ) and minimum area per molecule at the air/solution interface (A min ) were determined for both individual surfactants and their mixtures. The significant deviations from ideal behavior (attractive interactions) of the nonionic/ionic surfactant mixtures were determined. Mixtures of both AEO 9 /SDS and AEO 9 /CTAB exhibited synergism in surface tension reduction efficiency and mixed micelle formation, but neither exhibited synergism in surface tension reduction effectiveness.

“…Synergy [1] is defined here as the condition in which the properties of the mixture are better than those attainable with the individual components by themselves and can be predicted from molecular interactions between the two surfactants and relevant properties of the individual surfactants by themselves [1]. Recently, the molecular interactions in mixed systems involving conventional surfactants [18,19] and gemini surfactants [20][21][22][23] have been of academic and industrial interest.…”

Due to the potential use of amines as co-surfactants in microemulsions, the effect of adding alkylamines (C 4 -C 8 NH 2 ) on the aggregation properties of cationic gemini surfactants [pentanediyl-1, 5-bis(dimethylcetylammonium bromide) and hexanediyl-1, 6-bis(dimethylcetylammonium bromide), referred to as 16-5-16 and 16-6-16 compounds] has been studied using tensiometry at 303 K. Data on critical micelle concentration (CMC), the surface properties C 20 (the surfactant concentration required to reduce the surface tension by 20 mN/m), U max (maximum surface excess), A min (minimum surface area per molecule) evaluated from the surface tension versus surfactant concentration plot, the interaction parameters b r (for mixed monolayer formation at the aqueous solution/air interface), and b m (for mixed micelle formation in aqueous medium) are reported. A synergistic interaction was observed both in the micelle as well as at interface, as evident from interaction parameters. Theoretical models of Clint, Rubingh and Rosen were used to explain and compare the results. More synergistic interaction was observed in 16-5-16 as compared to 16-6-16. The CMC values of 16-s-16 (s = 5, 6) decreased with increasing amine concentrations and the extent of the effect followed the sequence: octylamine [ heptylamine [ hexylamine [ pentylamine [ butylamine.
