Formulation And Evaluation of Moisturizing Cream Containing Hibiscus Rosa-Sinensis Extract

Abstract

Background: Herbal cosmetics are gaining popularity due to their wide range of phytochemical properties. The powerful antioxidant activity of Hibiscus rosa-sinensis (HRS) is attributed to its phenolic and flavonoid compounds. HRS is a good option for topical products meant to safeguard and rejuvenate skin because of its bioactive ingredients. Aims: The study aimed to formulate and evaluate herbal cosmetic creams containing Hibiscus rosa-sinensis extract, focusing on phytochemical composition, antioxidant activity, stability, and rheological characteristics. Methodology: Phytochemical screening, total phenolic content (TPC), and total flavonoid content (TFC) were evaluated to confirm the extract’s antioxidant potential (TPC: 78.03±1.50 mg QE/g, TFC: 92.03±1.74 mg QE/g). Antioxidants capacity was assessed using DPPH and reducing power assays, showing inhibition levels up to 92.12%. Three cram formulations (F1 and F2 containing 4% of extract and F3 (placebo) were prepared and analyzed for organoleptic properties, stability under varying temperature, conductivity, and rheological behavior. Stability and parameters were recorded after storage at accelerated conditions. Results: Phytochemical evaluation confirmed the presence of strong antioxidant constituents. All formulations showed excellent physical stability, with no phase separation or major changes in organoleptic properties across different storage conditions. Conductivity remained consistent, and rheological analysis indicated desirable pseudo plastic, shear-thinning behavior ideal for topical applications. The optimized formulations demonstrated ease of application, good spread ability, and compliance with cosmetic quality standards. Conclusion: Overall, Hibiscus rosa-sinensis extract is used to make stable, smooth, and skin-beneficial cream. It is a natural and safe ingredient that works well in skincare products.
