        abstract = {The present study aimed to formulate and evaluate a herbal soap using orange peel (Citrus sinensis) extract as a natural active ingredient. Orange peel is rich in flavonoids, phenolics, and essential oils, which possess antioxidant, antimicrobial, and skin-protective properties. The extract was obtained using maceration, Soxhlet, and hydroalcoholic methods, and the hydroalcoholic extract showed the highest yield and was selected for formulation. The soap was prepared using a combination of coconut oil, palm oil, olive oil, sodium hydroxide, glycerin, and orange-peel extract. Six formulations (F1–F6) were developed and optimized using Box–Behnken Design under Quality by Design principles. The formulations were evaluated for physicochemical and functional properties including appearance, pH, hardness, foam height, foam retention, total fatty matter, cleansing ability, skin irritation, and stability. All formulations showed acceptable characteristics; however, formulation F6 demonstrated superior performance with highest hardness, foam stability, and cleansing efficiency. Phytochemical screening confirmed the presence of bioactive compounds responsible for antimicrobial and antioxidant activity. Stability studies indicated that all formulations remained stable over the study period. The study concludes that orange peel extract soap is an effective, eco-friendly, and safe herbal formulation with potential applications in skincare and hygiene products.},
