The carboxylic acid‐type Gemini surfactant (CGS12) was synthesized, and its micellization in aqueoussolution at different pH values at 25.0 °C was investigated. The results show that the critical micelle concentration (CMC) of CGS12 at different pH values is only 10−6 order of magnitude, and the pH has little effect on the CMC. Moreover, the interaction of CGS12 with amino acid surfactant of sodium
