Formulation and Evaluation of Walnut Shell Powder-Based Herbal Face Scrub Soap

Abstract

This study focuses on the formulation and evaluation of a walnut shell powder-based herbal facial scrub using natural ingredients.Plant-based cosmetics are becoming increasingly popular, because they are safer, more effective, and have fewer side effects than synthetic products.The aim of this research was to develop a multifunctional herbal scrub soap that cleanses, exfoliates and nourishes the skin.

The formulation was prepared using a glycerin soap base along with herbal ingredients such as neem, tulsi, orange peel powder, red lentil powder, and walnut shell powder as a natural exfoliating agent. Aloe vera gel and vitamin E were incorporated to enhance moisturizing and antioxidant properties, while fragrance was added to improve sensory appeal. The prepared soap was evaluated for several physicochemical parameters such as sensory properties, pH, foam height, foam retention, flammability, cleansing properties, viscosity, and roughness.

The results indicated that the formulated soap possessed good physical appearance, pleasant odor, and acceptable pH suitable for skin application. It showed good foaming ability, stability, and cleansing efficiency. The presence of walnut shell powder provided effective exfoliation without causing irritation, while other herbal ingredients contributed antimicrobial, soothing, and skin-enhancing properties.                   

In conclusion, the developed herbal face scrub soap was found to be safe, effective, and suitable for regular use. It can serve as a natural and eco-friendly alternative to commercially available synthetic scrub soaps. Further studies on stability and microbial analysis are recommended to enhance its commercial applicability.
