Formulation, Evaluation and Antimicrobial Efficiency of Herbal Handwash from Catechu

The present study focuses on the formulation, evaluation, and antimicrobial efficacy of an herbal handwash prepared using Acacia catechu (catechu) extract. With increasing awareness about the side effects of synthetic hand hygiene products, the demand for natural alternatives has surged. This study aimed to develop a safe, effective, and ecofriendly handwash using catechu, known for its traditional antimicrobial properties. The formulation was optimized with ingredients such as NaCMC, SLS, glycerine, and fragrance to ensure proper consistency, moisturizing effect, and aesthetic appeal. The handwash underwent thorough evaluation for physical parameters including pH (6.05), viscosity, spreadability, and skin irritation, along with antimicrobial testing against Staphylococcus aureus and Pseudomonas aeruginosa. Results revealed significant zones of inhibition (55 mm and 48 mm respectively), confirming broad-spectrum antimicrobial activity. The formulation remained stable over various temperatures and showed no adverse effects on the skin. These findings highlight the potential of catechu-based handwash as a viable natural alternative in both healthcare and general hygiene settings.
