“…ILs have also been widely explored as potential ionic surfactants with different areas and applications such as extraction of organic compounds, metal ions and radioactive isotopes [55][56], as template to produce micro/mesoporous materials [57][58], in microemulsion [59][60][61]. The surfactant properties of ILs are easily understood if we consider that these compounds generally have a well-defined structure with hydrophilic character and another with hydrophobic character, i.e.…”

“…28 9 Our previous work showed that after altering a quarter of TX-100 by [C 8 mim][Cl] in castor oil-based ionic liquid microemulsions, the driving force of constructing microemulsions would be enhanced and the S ME in the pseudoternary phase diagram would be enlarged. This section was conducted to further identify the effect of mass ratio between TX-100 and [C 8 [BF 4 ] systems at (298 ± 0.5) K with K m at 4:1, respectively, and the intuitive comparison of single-phase region areas of different cosurfactant-based microemulsion was presented in Figure 10. From the results, it is noticeable that the area under the clear region increased as expected when we increased the carbon chain length of cosurfactant to six.…”

“…Moreover, ionic liquid microemulsification can overcome the immiscibility of castor oil and polar phases, and enhance their viscosity−temperature characteristics and friction-reduction properties. 8 Ionic liquid microemulsions were defined as systems in which ionic liquids substituted oils, water, or surfactants of traditional microemulsions. 9 The complex characteristics of the phase behavior and solubilization parameters of different components were the necessary basis for discussion of the properties.…”

Castor oil-based ionic liquid microemulsions are promising alternatives for petroleum-based biolubricant basestocks. This study presents the phase behavior of castor oil-based ionic liquid microemulsions through phase manifestation, and the areas of the single-phase domain (S ME ) were calculated accordingly to further illustrate the phase-forming capacities of the designed microemulsions. The results indicated that the phase-forming capacities of castor oil-based ionic liquid microemulsions depended largely on the ionic liquid ions, surfactant types, and cosurfactant chain lengths. The S ME of different anion-based ionic liquid microemulsions showed the following sequences: [BMIM][Tf 2 N]-based > [BMIM][PF 6 ]-based > [BMIM][BF 4 ]-based. The longer carbon chain of ionic liquid cations in single surfactant-based systems and the larger percentage of ionic liquid-based surfactant in mixed surfactants-based systems both gave rise to the phase-forming capacities of castor oil-based ionic liquid microemulsions. Given the presence of ionic liquid−castor oil amphiphilic balance in the designed systems, the castor oil−surfactant micelles achieved maximum solubilization capacity for [BMIM][BF 4 ] when the ethoxylated groups' number of surfactant was about eight in single surfactant microemulsion.In addition, n-hexanol donated a higher phase-forming capacity than n-butanol, while n-octanol brought about a different phase behavior due to the spontaneous curvature effect and oil nature of long-chain alcohols (C ≥ 7) in the castor-oil based ionic liquid microemulsions. Thus, this study presented useful information for formulating optimum castor oil-based ionic liquid microemulsion biolubricants based on different ionic liquids, surfactants, and cosurfactants, which were not evaluated in previous research.
