Interest in biosurfactants has been steadily increasing in recent years due to their diversity, environmentally friendly nature such as nontoxicity and excellent biodegradability, possibility of large-scale production and potential applications in environmental protection. In this study, amino acid biosurfactants were synthesized for cosmetics and household product applications. Economic and environmentally friendly biosurfactants with excellent biodegradable characteristics were derived from renewable vegetable oils such as cottonseed oil, palm oil, and coconut oil. The structure of the resulting products was elucidated by 1H NMR, and 13C NMR spectroscopies and environmental compatibility such as biodegradability and acute oral toxicity was evaluated. The interfacial characteristics of the synthesized surfactant including surface tension, critical micelle concentration, interfacial tension, wetting property, emulsification activity, viscosity and foam property have been examined. |
