Formulation and Antimicrobial Evaluation of a Polyherbal Face Wash Gel Using Citrus and Medicinal Plant Extracts

The present study focuses on the formulation and evaluation of a herbal face wash gel using natural ingredients known for their skincare benefits. The main objective was to develop a safe, effective, and eco-friendly formulation incorporating orange peel, rosemary, and honey, each recognized for their antibacterial, antioxidant, moisturizing, and rejuvenating properties. The formulation process involved extraction via maceration with rosewater, followed by gel formation using Carbopol 940, preservatives, foaming agents, and neutralizers. Three formulations (F1, F2, F3) were prepared with varying concentrations of herbal extracts, and F3 was identified as the most stable and effective. The formulated gels were evaluated through physicochemical and performance-based parameters including pH, viscosity, spreadability, grittiness, foamability, washability, irritancy, and antimicrobial activity against Staphylococcus aureus and Escherichia coli. The F3 batch showed a pH of 6.54, high spreadability (8.33 g·cm/s), suitable viscosity (5200 cP), and non-irritant behavior. The zone of inhibition in the antimicrobial assay confirmed its antibacterial efficacy. Stability studies showed no significant change over three months. Overall, the study concludes that herbal face wash formulations can serve as effective and natural alternatives to synthetic products, promoting healthy skin without adverse effects.
