Bio-based surfactants are the one using renewable biomass as the main starting material. Bio-based surfactants, different from petroleum-based surfactants, have attracted more attentions from scientific and industrial fields due to the renewable resource and outstanding surface/interfacial properties. Interfacial tension and dynamic light scattering measurement were utilized to evaluate the interfacial properties and aggregation behavior of bio-based zwitterionic surfactants derived from waste cooking oils in aqueous solution. The bio-based surfactants show excellent interfacial properties in the absence of alkali and remain ultra-low oil-water interfacial tensions at temperatures 50~70 ℃ and pH 7 to 12; the bio-based surfactants solution exhibits good interfacial properties in different simulated oil-water samples; the interfacial properties are not effected by the storage temperature of 50 ℃, -20 ℃ and 4 ℃; the hydrodynamic diameters of the aggregates in different water samples are in the range of 10 to 30 nm and inorganic salt ions have little effect on the size of the aggregates. The bio-based surfactants derived from waste cooking oils are potentital substitutes to petroleum-based surfactants for many applications, especially in enhanced oil recovery.

Key words: waste cooking oil, bio-based surfactant, zwitterionic surfactant, no-alkali system, ultra-low interfacial tensions, enhanced oil recovery
