Abstract
Bio-based surfactants have attracted increasing attention due to their renewable resources and excellent surface properties. In this study, a novel bio-based sulfonic zwitterionic surfactant (BSZS) derived from transgenic soybean oil was prepared using a simple reaction route with two steps of the amidation and quaterisation. The bio-based sulfonic zwitterionic surfactant showed a critical micelle concentration (CMC) as low as 33.34 mg/L with a surface tension of 28.50 mN/m. In addition, it also showed good performance in foamability, emulsibility, and wettability. The excellent performances indicated the great potential applications of the bio-based sulfonic surfactant from vegetable oils in both daily life and industrial fields.Bio-based surfactants have attracted increasing attention due to their renewable resources and excellent surface properties.
