Preparation of Eco-Friendly Mosquito Repellent Jelly Using Essential Oils and Evaluation of Its Efficacy

The developed mosquito-repellent jelly represents an innovative and environmentally sustainable solution without relying on toxic chemicals. It was formulated using five essential oils viz., citronella, lemongrass, clove, neem, and lavender to ensure safety for human skin and eyes, which provide effective repellency. The jelly exhibited 100% effectiveness during the first two hours of application. Although its efficacy gradually declined, reducing to 70% over the subsequent three hours and further decreasing to 40% after four hours. The physical and chemical properties of the jelly were thoroughly evaluated through organoleptic analysis, repellency testing, skin patch testing, eye irritation testing, and inhalation testing, all of which confirmed its safety for further use. This mosquito-repellent jelly offers a natural, eco-friendly alternative to conventional chemical repellents, aligning with the growing demand for non-toxic solution in personal care. However, to extend the effective repellency of the mosquito-repellent jelly, an innovative method is required to lock the aroma of the gel, which is responsible for its repellent action.
