Effect of added ionic liquid on aqueous Triton X-100 micelles

Effect of [C n mim][Br] Based Ionic Liquids on the Aggregation Behavior of Tetradecyltrimethylammonium Bromide in Aqueous Medium

“…To knowledge, the first report on cationic surfactant self-assembly in a non-aqueous medium was published in 1967 [30]. The aggregation behavior of the ionic [19, 20, 25-29, 31, 33-38, 40], non-ionic [19,23,24,32,41] and zwitterionic [21,22] surfactants with a range of ILs having various cations and anions has been studied in detail. 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].…”

“…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 general, the effect of ILs on the aggregation behavior of surfactants is governed by electrostatic and hydrophobic interactions, which in turn depend on the structural properties of the IL molecule, including the head group, counter ion type and alkyl chain length, as well as the concentration of the ILs in the medium [26,27,34,35,37,47]. At lower concentrations, ILs behave as electrolytes and decreases the CMC values of aqueous surfactants, whereas at higher concentrations the CMC of the aqueous surfactant increases, which may be due to cosolvent-type behavior of the ILs [22,24,43]. The cations and anions of the ILs have a profound impact on the physicochemical properties of aqueous surfactant solutions [20][21][22][23][24][25][26][27]47].…”

Various Self-Assembly Behaviors of Amphiphilic Molecules in Ionic Liquids

“…BmimPF 6 can partition into the Triton X-100 micellar phase both close to the core as well as in the palisade layer of Triton X-100. They suggested the presence of favorable interactions such as hydrogen bonding between C-2 proton of imidazolium cation and ethoxy/hydroxyl, between PF 6 − and H of the Triton X-100 hydroxyl terminal, and dipoleinduced dipole type of interaction between Triton X-100 phenyl π-cloud and 1-alkyl-3-methylimidazolium cation between bmimPF 6 and Triton X-100 [26]. In addition to emimTf 2 N, Triton X-100 was shown to aggregate and form micellar aggregation in bmimBF 4 and bmimPF 6 , respectively [27].…”

Phase Manifestation and Formation of Nanoemulsions Composed of Imidazolium-based Ionic Liquid, Tween 80/Span 80 and Labrafac Lipophile WL 1349

“…The first ILbased microemulsion was reported by Gao et al (2004) where an IL was used to replace water content (Zech et al 2010). In the subsequent investigations, various kinds of IL-based microemulsions have been prepared (Zech et al 2010;Harrar et al 2011;Behera, Dahiya & Pandey 2007;Zhang et al 2011;Cheng et al 2007). In most of the studies on ILbased microemulsions, the IL, such as 1-butyl-3-methylimidazolium tetrafluoroborate (C 4 mim) (BF 4 ), was used as a replacement for water .…”
