Formulation and Evaluation of Mosquito Repellent Polyherbal Emulgel as a Novel Approach

Mosquito-borne diseases are posing a significant global health challenge, indicating the need for safer and more effective repellant. In this study, a novel herbal emulgel was formulated as a mosquito repellent using ethanol extracts of Azadirachta indica, Piper nigrum, and Calotropis gigantea. Suitable emulsifying and gelling agents were incorporated to ensure a stable, smooth, and skin-friendly product. The formulation was evaluated for physical parameters including pH, viscosity, spreadability, and washability, all of which were within acceptable ranges for topical use. Additional tests, such as irritancy studies, FTIR spectroscopy, and stability analysis, confirmed that the emulgel was non-irritant, physically stable, and safe for application. The FTIR analysis supported the compatibility of the herbal extracts within the formulation matrix. Stability studies further demonstrated that the emulgel retained its efficacy and consistency over time. The results validate that the developed herbal emulgel is an effective, natural, and safe alternative to synthetic mosquito repellents. It presents a promising solution for the prevention of mosquito-borne diseases through a plant-based, skin-compatible approach.
