“…The presence of ester group‐containing tail along with the caffeinium head group in the SAILs series is responsible for reduced CMC values [19,27] . Further, the cat‐anionic mixtures (SAIL‐DS) have still lower CMC values than both the pure components (SAILs and SDS) as shown in Figure 1B and Table 1 [30] . The significant reduction in CMC values of cat‐anionic mixtures is due to formation of ion‐pair complexes having strong electrostatic interactions between the oppositely charged head groups of SAILs and SDS.…”

Caffeinium-based surface-active ionic liquids (SAILs), (1-(2alkanoyl oxy) ethylcaffeinium bromide), [C n Ecaf]Br with variable chain length (n = 12, 14, 16) were synthesized and their molecular structures were explored by multiple spectral techniques. The critical micelle concentration (CMC) of pure SAILs and their mixtures with sodium dodecyl sulfate (SAIL-DS) in aqueous solution was determined by employing various techniques at 298 K. The tensiometry and dynamic light scattering (DLS) techniques have been employed to gain insight about the interfacial behavior and aggregate size of catanionic mixtures in aqueous solution. Interestingly, the interaction parameters (X m 1 ; b m ) showed strong synergism between these two oppositely charged molecules. Further, it was found that SAIL-DS cat-anionic mixtures exhibit excellent adsorption efficacy and are more effective in lowering the surface tension of water as compared to pure SAILs. The DLS results showed the formation of mixed-size aggregates in SAIL-DS systems. The contact angle and wetting properties of pure SAILs over the parafilm surface were also determined using a static sessile drop method. Further, MTT assay was used to determine the biocompatibility of SAILs on Human embryonic kidney (HEK-293) cell line and in-vitro anti-cancer activity on Lung cancer cells (A549). These SAILs displayed substantial cytotoxicity against cancerous cells, indicating that they could be useful in a variety of biological applications.

“…A synergistic interaction is observed between N-lauryl sarcosine sodium and 1-dodecyl-3-methylimidazolium bromide, 38 while the CMC of the mixed system of the biamphiphilic ionic liquid 3-methyl-1-pentylimidazoliumdodecylsulfate [C 5 mim][C 12 SO 4 ] and sodium dioctylsulfosuccinate increases with an increase in the mole fraction of the IL, presenting an antagonistic behavior. 20 The mixed aggregates of sodium dodecylbenzenesulfonate and 1-alkyl-3methylimidazolium chloride-based ionic liquids formed by synergistic interaction find applications in the preparation of silver nanoparticles. 39 Das et al 40 In the present communication, we have described a comprehensive assessment of the interactional behavior of C 16 mimCl with sodium oleate and sodium linoleate using surface tension measurements.…”

“…The fascinating phase behavior of such mixed systems arises due to the interplay of the electrostatic interaction, hydrophobic interaction, H-bonding, and steric effect. The interaction of SAILs with cationic, , anionic, , nonionic, , Gemini, , Pluronic, − and Tetronic , surfactants has been investigated by several researchers. The synergistic interaction in the mixed systems comprising 1-dodecyl-3-methylimidazolium chloride (C 12 mimCl) with the nonionic surfactant Triton X-100 or Triton X-405 has been reported by Farahani et al and it was revealed that micellization is spontaneous in nature and more favorable in the presence of Triton X-100.…”

The present investigation is undertaken to develop and characterize mixed aggregates formed from a surface-active ionic liquid (SAIL), 1-hexadecyl-3-methylimidazolium chloride (C16mimCl), and two anionic surfactants, sodium oleate or sodium linoleate. The micellization behavior of the cationic SAIL and anionic surfactants was investigated using the tensiometric method. The obtained surface tension data have been analyzed by Rubingh’s regular solution theory (RST) and Clint’s theory for mixed binary systems. Surface tension data offer additional insight into the change in the critical micelle concentration (CMC) and surface activity as a function of the mole fraction of the SAIL. The negative value of interaction parameters and low CMC values imply the synergism between micelle-forming units at the all-mole fraction investigated. The interfacial and thermodynamic parameters for mixed micelles and mixed monolayers at various mole fractions of C16mimCl have been calculated and discussed. A thorough insight into the correlation between the molecular orbital energy level of C16mimCl and sodium oleate or sodium linoleate is provided by optimized parameters, which are obtained from a computational simulation approach. The obtained results highlight the compatibility of SAILs with anionic surfactants in formulating the mixed nanoaggregates for desired applications.

“…Therefore, in the present work, the changes in the physicochemical properties of CTAB in aqueous solution upon addition of R 4 N + Br − at different temperatures have been investigated by using conductometric technique and calculating various thermodynamic parameters which are useful to know about the thermal stability of these ternary systems. Additionally, UV–Visible, Fourier transform infrared (FTIR) and 1 H‐NMR spectroscopy techniques have also been applied to gain a better understanding of the thermal stability and the aggregation process of these ternary systems in the bulk and at the air–water interface (Chauhan et al, 2014, 2018; Kumar, Katal, & Rawat, 2018; Pal et al, 2021).…”

The influence of tetraalkylammonium salts, viz., tetraethylammonium, tetrapropylammonium, and tetrabutylammonium bromides (0.005, 0.010, 0.015 mol kg−1) on the micellar behavior of aqueous solutions of the cationic surfactant cetyltrimethylammonium bromide (CTAB, 0.2–2 mmol kg−1) over the 298.15–313.15 K temperature range has been studied by conductometric method. From conductivity versus surfactant concentration plots, the critical micelle concentration (CMC) of CTAB has been determined, which shows that the tetraalkylammonium bromides promote the formation of CTAB aggregates. Further, from the temperature dependence of CMC values, the degree of ionization, the counterion binding constant along with some thermodynamic parameters of micellization, such as standard free energy change (), standard enthalpy change (), standard entropy change () have been calculated. From the values of , and , it has been concluded that our ternary system is both enthalpy as well as entropy controlled. Similar CMC values were obtained from UV–Visible spectrometry measurements, using pyrene as a probe at ambient temperature. Also 1H‐NMR and FTIR methods give a greater understanding of the molecular scale interactions between the tetraalkylammonium bromides and the cationic surfactant.
