Interest in biosurfactants has been steadily increasing due to their diversity, environment friendly nature such as nontoxicity and excellent biodegradability, possibility of large-scale production, selectivity, performance under extreme conditions, and potential applications in environmental protection. In this study, fatty acid biosurfactants were synthesized from renewable vegetable oils such as rapeseed oil, cottonseed oil, palm oil, and coconut oil for cosmetic and household products applications. The structure of the resulting products was elucidated by FT-IR, 1H NMR, and 13C NMR spectroscopies and interfacial characteristics of the synthesized surfactant including critical micelle concentration, surface tension, interfacial tension, wetting property, emulsification activity, viscosity and foam property have been examined. |
