Formulation and Evaluation of Polyherbal Soap

Abstract

The present study focuses on the formulation and evaluation of a polyherbal soap utilizing natural plant-based ingredients known for their dermatological benefits. With growing consumer preference for herbal cosmetics due to their safety, minimal side effects, and therapeutic efficacy, this study integrates traditional herbal knowledge with modern formulation techniques. The soap was prepared using a glycerine base combined with herbal ingredients such as aloe vera gel, turmeric powder, neem, tulasi, white lotus flower powder, jasmine, and vitamin E. Aloe vera served as the primary moisturizing agent, while turmeric and neem contributed anti-inflammatory and antimicrobial properties. The formulation process involved melting the soap base, incorporating powdered herbal components, and molding into various shapes. Evaluation parameters included pH, color, shape, odor, foam height, foam retention, skin irritation, and percentage of free alkali. The results demonstrated a stable, mildly alkaline soap (pH 8) with satisfactory foaming properties, pleasing odor, no skin irritation, and minimal free alkali content (0.22%). The findings suggest that the formulated herbal soap is safe, effective, and suitable for skincare applications, promoting both cleansing and therapeutic benefits. This study highlights the potential of herbal cosmetics as sustainable and consumer-friendly alternatives in the personal care industry.
