Preparation and Characterization of Biodegradable Diethanolamide Surfactant from Cotton Seed Oil

Abstract

The heavy reliance of cosmetics, paint, and other manufacturing industries on edible plant-based oils has driven up the cost of these oils, leading to a significant imbalance between their domestic and industrial usage. With a projected population surge on the horizon, competition for these oils between domestic and industrial sectors could escalate, potentially creating an unsustainable situation for consumers. To address this challenge, this research explores and characterizes biosurfactants derived from cottonseed oil as an alternative fixed oil source. This renewable source shows promise as a commercial raw material for feedstock and oil-based industries, aligning with Sustainable Development Goal 11 (SDG 11) on sustainable production. In this study, diethanolamide biosurfactant was prepared from cottonseed oil using established analytical methods. The modified product was characterize using UV-Visible and Fourier Transform – Infrared (FTIR) Spectroscopy.
