Development and evaluation of natural polyherbal soap

Abstract

This research focuses on the formulation of polyherbal soaps using natural ingredients such as neem, aloe vera, shikakai, rose water, and Multani mitti. The primary objective was to develop an eco-friendly, skin-beneficial soap with antibacterial, antioxidant, and skin-conditioning properties, as opposed to synthetic soaps containing harsh chemicals. The soap base was formulated using a cold process method, incorporating key ingredients at varying concentrations, such as neem oil (Azadirachta indica), aloe vera gel (Aloe barbadensis), and others, to enhance the soap’s effectiveness in treating skin issues. The study evaluates the prepared polyherbal soap formulations (F1, F2, F3, F4) based on organoleptic characters, pH, foam height, foam retention, irritation, and antimicrobial activity. The results showed that all formulations exhibited desirable attributes such as a pleasant fragrance, good lather, and no irritation upon skin application. The pH remained stable at 9 across all formulations, and antimicrobial activity was observed, with the F4 formulation demonstrating the highest inhibition zone (14mm) against E. coli. The findings suggest that polyherbal soaps possess superior therapeutic properties compared to conventional synthetic soaps, offering benefits such as enhanced skin hydration, acne control, and protection against infections. These formulations are considered promising for inclusion in skincare regimens, with minimal chemical content and more holistic benefits. Further clinical studies are recommended to validate these results and explore the broader potential of polyherbal soaps in skincare applications.
