Formulation, optimization and evaluation of multi-herb soap for dermatological benefits

Abstract This study explores the formulation and evaluation of a natural, multi-herb soap incorporating various medicinal plant extracts known for their skin-beneficial properties. The soap is developed using a blend of herbal ingredients such as Orange peel powder, turmeric,and aloe vera, each selected for their antimicrobial, anti-inflammatory, skin brightening and moisturizing effects. Through a cold process method, the herbs are integrated into a base of natural oils to create a gentle, chemical-free cleansing bar. The final product is assessed for physical characteristics, pH, lathering ability, and shelf stability. Results suggest that the multi-herb soap not only meets quality standards but also offers potential therapeutic benefits, making it a promising alternative to commercial soaps containing synthetic additives.
