Sugar-based surfactants can be obtained from renewable materials such as fatty alcohols and sugars and are easily biodegradable. Due to their unique solution and interfacial properties as well as their benign environmental pro le, they are nding more and more industrial applications for detergency, emulsi cation, dispersion, wetting, solubilization, etc. [1-4].
