This article describes the synthesis, properties and potential applications of new cationic surfactants based on natural glycine betaine and vegetable oils as renewable raw materials. Convenient procedures were developed on a multigram scale using environmentally friendly starting materials to provide glycine betaine-derived esters and amides. Some readily biodegradable formulations containing ester-type surfactant were found to exhibit remarkable emulsifying properties for road making applications and they are now under industrial development using green solvent-free processes. Bipolar bolaamphiphiles possessing two cationic glycine betaine moieties were synthesized as monomers for the preparation of original drug delivery liposomal systems.
