Superior thermal stability gel emulsion produced by low concentration Gemini surfactant

► Gemini surfactant can be used as a high efficiency emulsifier to produce gel emulsions. ► The viscoelasticity and thermal stability of the gel emulsions increase along with raising the surfactant concentration. ► The gel emulsions produced by Gemini surfactant show superior thermal stability compared with gel emulsion produced by the monomeric surfactant.
