Formulation and Evaluation of an Herbal Oral Mouthwash Utilizing Natural Foaming Agents for Improved Foaming Efficiency and Oral Hygiene Activity

Abstract

Oral hygiene plays a crucial role in maintaining overall health, and the use of mouthwashes has become an effective adjunct to mechanical plaque control. However, most conventional mouthwashes contain synthetic surfactants and chemical additives that may cause irritation or long-term adverse effects. In the present study, a herbal oral mouthwash was formulated and evaluated using natural foaming agents to enhance foaming efficiency and improve user acceptability. The formulation was developed using medicinal plant extracts including Ashwagandha (Withania somnifera), Amla (Phyllanthus emblica), Fenugreek (Trigonella foenum-graecum), along with essential oils of Clove (Syzygium aromaticum) and Cinnamon (Cinnamomum verum), and menthol for refreshing activity. Glycerin was incorporated as a humectant and distilled water as the solvent system. The herbal combination was selected for its known antimicrobial, anti-inflammatory, and antioxidant properties, contributing to overall oral hygiene improvement. Natural foaming components were included to enhance foam formation, stability, and cleansing action without the use of harsh synthetic surfactants. The formulated mouthwash was evaluated for organoleptic properties, pH, foaming ability, foam stability, and antimicrobial activity. The results indicated satisfactory foaming efficiency, acceptable physicochemical characteristics, and promising antibacterial effects against common oral pathogens. The study suggests that herbal-based mouthwash with natural foaming agents can serve as a safe, effective, and eco-friendly alternative to conventional formulations, improving oral hygiene while minimizing chemical exposure.
