Interest in biosurfactants has been steadily increasing in recent years due to their diversity, environmentally friendly nature such as nontoxicity and excellent biodegradability, selectivity, performance under extreme conditions, and potential applications in environmental protection. In this study, saccharide polymeric biosurfactants with excellent biodegradable characteristics were synthesized from renewable vegetable oils such as cottonseed oil, palm oil, and coconut oil for cosmetic products applications. The structure of the resulting products was elucidated by 1H NMR, and 13C NMR spectroscopies and environmental compatibility of the synthesized polymeric surfactants such as biodegradability, acute oral toxicity, skin and eye irritation was also evaluated. The interfacial properties of synthesized polymeric surfactants have been evaluated such as CMC, static and dynamic surface tension, interfacial tension, wetting property, emulsification activity, viscosity, and foam property. |
