Research Advance of Cardanol-based Surfactants

This paper reviews recent progress in the cardanol-based surfactants.Especially,cardanol-based anionic surfactant(cardanol sulfonate,cardanol sulfate,cardanol carboxylate) and nonionic surfactants have been widely researched and deve-loped.However,the study of cardanol-based cationic surfactants has not yet been reported.In addition,this paper also prospects the research and application of the cardanol-based surfactants in future.
