Formulation And Evaluation of a Water -Based Sunscreen Lotion Incorporating Glycine Max Extract
Year: 2025
Type: article
Abstract: The present study focuses on the formulation and evaluation of a water-based sunscreen lotion utilizing Glycine max (soybean) extract, a natural source of isoflavones, flavonoids, and antioxidants with known photoprotective properties. In light of growing concerns over the safety and environmental impact of synthetic UV filters, the use of herbal alternatives offers a promising solution. The extract was prepared through cold maceration, followed by its incorporation into lotion formulations at varying concentrations. The prepared formulations were assessed for organoleptic properties, pH, spreadability, homogeneity, extrudability, and Sun Protection Factor (SPF). Results demonstrated favorable physical stability, good aesthetic attributes, and SPF values increasing proportionally with the concentration of Glycine max extract. The highest SPF recorded was 21.66 for the formulation with 1.5% extract. These findings suggest that Glycine max extract serves as a viable, safe, and eco-friendly alternative for natural sunscreen formulations. Further studies including in vivo testing are warranted to substantiate these results.
