Synthesis of (2-hydroxyl-3-butoxyl) propyl-succinyl-chitosan (HBP-SCCHS) – an amino sugar anionic surfactant under Microwave Irradiation and its application;(TJPS-2021-0086.R1)

Abstract

Introduction: Chitosan, a biopolymer with 97% degree of deacetylation was used herein, to synthesize an amino sugar anionic surfactant of varied alkyl chain length, using a microwave assisted synthesis. We were also examined their properties in aqueous form. Objectives: The objectives of the study were to increase the surface activity and water solubility of chitosan derivatives. Materials and Methods: Structural features and crystallinity were confirmed using FT-IR, ¹H-NMR and XRD. The chitosan by itself was found to have weak surface-active properties since, it has no hydrophobic segment. Results: The microwave assisted synthesized sugar-amino based anionic surfactant, HBP-SCCHS was found to have excellent surface-active and detergency properties. The aggregation behavior of amino sugar anionic surfactant was characterized by surface tension; which indicated that it had good surface activity. Conclusion: We believe that good surface activities of synthesized water-soluble surfactants can be used in the formulations of face wash, body wash, liquid detergents, more applications in pharmaceutical, medicine and food industry, etc.
