Alkyd resin prepared from Gossypium hirsutum (cotton seed) seed oil and immersed in silver nanoparticles has been characterized and evaluated using standard analytical methods. Gas Chromatography-Mass Spectrometry (GCMS) was used to determine the fatty acid profile of the seed oil extract which was physicochemically characterized using AOAC standard method. The results obtained are as follows: Iodine value; 102.36g I₂/100g, Acid value; 3.19 mgKOH/g, Saponification value; 202.32 mg/KOH/g, Refractive index; 1.46, Specific gravity; 0.91 and Moisture content; 1.20. The alkyd resin was prepared using alcoholysis-polyesterification reaction. The prepared resin was then immersed in silver benzoate to give Gossypium hirsutum immersed silver nanoparticle alkyd resin (GHSOR-AgNps) and the formulated resin was analyzed using Ultraviolet-Visible spectroscopy (UV), Fourier Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscopy (SEM). UV-visible spectroscopy was used to analyze the silver benzoate salt. The performance of the formulated resin was assessed and revealed thus: soluble in both polar and non-polar organic solvents used in the study, dried through after 24 hours, showed chemical resistance to 0.1M NaOH with total removal, and its acid value was below 10 mgKOH/g. Therefore, Gossypium hirsutum seed oil (GHSO) has been shown to be a cost-effective, renewable and sustainable feedstock for alkyd resin production in the coating industry.
