“…of the ILs in solution. Trends in conductance of aqueous cationic TTAB in the presence of ILs are similar to those observed by Zhang et al [48] for the aqueous Triton X-100 surfactant system in the presence of [C 12 mim][BF 4 ]; these trends are different from those observed for aqueous cationic, anionic, nonionic and aqueous zwitterionic surfactants upon addition of IL [21][22][23][24][25][26][27][28][29][36][37][38][39][40]. For a fixed concentration of TTAB, as the concentration of the ILs was increased from 0.2 to 1.0 wt%, the specific conductance increased by a reasonable amount.…”

“…The CMC values are presented in Table 2 and are found to be in good [64]. Several other reports suggest either no change in the CMC [24], decrease in the CMC [22,[25][26][27][65][66][67][68][69], or increase in the CMC [23,28,29,[36][37][38]40] upon addition of the ILs. Looking at these results it is premature to correlate the ILs with the common electrolytes for properties of aqueous solutions with TTAB.…”

“…The effect of the hydrophobicity of the alkyl groups of the ILs and surfactant anions on the CMCs, size distributions and thermodynamics of micellization has also been investigated [27,34,35]. Physicochemical properties of aqueous cationic, anionic, non-ionic and zwitterionic surfactants such as the CMC, size of the aggregates, aggregation number, dipolarity and microfluidity have been systematically modified by adding ILs [21][22][23][24][25][26] 4 ] on the physicochemical properties of aqueous anionic and cationic surfactants [28,29,[36][37][38][39][40]. ILs composed of different cations and anions have been extensively studied by various research groups in the field of colloid and interface science and some extensive reviews are available [41][42][43][44][45][46][47][48].…”

In order to gain insight into the role of environmentally benign imidazolium based ionic liquids (ILs) to alter the physicochemical properties of single chain cationic surfactants, we have investigated the effect of 1-hexyl-3-methylimidazolium bromide ([C 6 mim][Br]) and 1-octyl-3-methylimidazolium bromide ([C 8 mim][Br]) on the aggregation behavior of aqueous tetradecyltrimethylammonium bromide (TTAB). The critical micelle concentration (CMC) of TTAB at different concentrations of ILs was determined through conductance, surface tension, spectral change of a dye by UV-Vis measurement, and the pyrene fluorescence probe measurement techniques at 298.15 K. Decreasing of the CMC of aqueous TTAB with increasing ILs concentration proves the micellization is favorable. The effect of ILs on the properties of TTAB was verified by using NaBr. Surface tension measurements complimented by dynamic light scattering (DLS) data revealed the packing density of TTAB aggregates at different concentrations of ILs. The effective area of TTAB molecules at the air/water interface was calculated by the Gibbs adsorption isotherm and found to decrease up to 0.6 wt% of ILs followed by an increase at higher concentration. DLS data revealed an increase in micellar size of TTAB at higher concentration of IL with decrease in the aggregation number (N agg ), determined by the fluorescence quenching method.

“…Above 10.0 wt.% of IL, due to high amount of IL in the solution media, huge number of IL molecules surrounds the TTAB monomers, thus allows lesser number of surfactant molecules to form the micellar aggregate. These results are different from what observed in case of our previous investigations SDS + [bdmim][Cl]/[bdmim] [BF 4 ], as there cmc increased and N agg decreased with addition of IL [30,31]. Our N agg results re-emphasize the significant effect of IL [bdmim] [Br] in modifying the physicochemical properties of aqueous TTAB solutions.…”

“…In our previous work, we have successfully demonstrated the effect of trisubstituted imidazolium based ILs, 1-butyl-2,3-dimethylimidazolium chloride [bdmim] [Cl], and 1-butyl-2,3-dimethylimidazolium tetrafluoroborate [bdmim] [BF 4 ] in altering the micellization properties of anionic surfactant SDS in aqueous media [30,31]. Therein we have clearly shown the effect due to change in anion of IL on surfactant properties.…”

The micellization and surface-active behavior of zwitterionic surfactant N-dodecyl-N,N-dimethyl-3-ammonio-1-propanesulfonate (SB-12) in aqueous media were investigated in the absence and presence of different alkyl-appended and benzyl-appended ionic liquids (IL)The characteristics of self-organization processes in SB-12 + IL/water systems include critical micelle concentration (cmc), aggregation number (N agg ), micellar size (D), surface, and adsorption parameters. These parameters were determined by the fluorescence and surface tension measurements. In SB-12 solutions, cmc were found to be decreasing to different extents in the presence of all the studied IL than in pure water. The addition of IL [hdmim][Br] decreases the cmc of aqueous SB-12 to rather a low extent. The other three IL show a prominent lowering in cmc of surfactant SB-12 to different magnitude. The maximum lowering in cmc was observed due to addition of benzyl-appended IL [bzdmim] [Cl]. The aggregation number of aqueous SB-12 solution obtained in general is higher at high wt.% of added IL. The average micellar size was also found to increase upon addition of IL. Both IL anions and cations interacted with the charged centers present on the zwitterionic surfactant SB-12, which caused a substantial increase in the surface activity.Keywords Critical micelle concentration Á Benzyl appended ionic liquid Á SB-12 Á Tensiometry Á Fluoremetry J Surfact Deterg (2019) 22: 327-338. Synthesis of 1-Benzyl-2,3-Dimethylimidazolium Chloride [bzdmim][Cl]IL [bzdmim][Cl] was synthesized by slowly adding slight excess of benzyl chloride (10 g, 79 mmol) to 1,2dimethylimidazole (7.2 g, 75 mmol) in a round bottom flask. The resulting solution was refluxed between 60 and 70 C for 24 h under a N 2 atmosphere. After this, the reaction mixture was allowed to cool down and the product obtained was washed three times using diethyl ether. The solid product obtained dried under vacuum gives 1-benzyl-2,3dimethylimidazolium chloride [bzdmim] [Cl]. The reaction yields 85% of product. The water content determined through Karl-Fisher examination was found to be <380 ppm. 328 J Surfact Deterg J Surfact Deterg (2019) 22: 327-338
