Abstract: Due to its special molecular structure, Gemini surfactants possess many excellent properties over traditional surfactants, such as surface activity, critical micelle concentration, wettability, water solubility at low temperature, solubilization, rheological property, and lime soap dispersing power. Research and developmental prospects of bio-based Gemini surfactants were emphatically analyzed because of its combined characteristics of Gemini surfactants and natural products. Synthesis and applications of Gemini surfactants made from sugar, oil and rosin were introduced respectively. It is pointed out that convenient synthetic methods and effective mixed systems of Gemini and traditional surfactants will be the research focus in the near future.
