Synergistic effects of cationic gemini 1,4-bis(3-dodecylimidazolium-1-yl) butane bromide (C₁₂鈥?鈥揅₁₂)Br₂ and anionic sodium lauryl sulfate (SLS) on the interfacial composition, solubility, and solubilization capacity of the microemulsions were investigated. When the mole fractions of (C₁₂鈥?鈥揅₁₂)Br₂ in a (C₁₂鈥?鈥揅₁₂)Br₂ and SLS mixture (X_{(C12鈥?鈥揅12)Br2}) is in the ranges of 0.7 to 1 and 0 to 0.1, the three-phase microemulsion region appears. The solubilization capacity (SP*) of the microemulsions containing both (C₁₂鈭?鈭扖₁₂)Br₂ and SLS surfactants become much greater in contrast to the microemulsions that are either (C₁₂鈥?鈥揅₁₂)Br₂-based or SLS-based. The solubilization capacity (SP*) reaches a peak value at X_{(C12鈥?鈥揅12)Br2} = 0.7. The effects of oils, NaCl contents, and temperatures, on the oil +(C₁₂鈥?鈥揅₁₂)Br₂ + SLS + butan-1-ol + aqueous NaCl microemulsion system鈥檚 蔚鈥撐?phase diagrams were also discussed.
