Abstract

Neem (Azadirachta Indica) is one of India's most valued traditional medicinal herbs, with each part of the tree holding distinct medicinal properties. Mosquito-borne diseases, which pose a significant global health threat, require developing alternative mosquito-repellent solutions. This research explores the potential of neem-scented candles as a natural repellent due to neem's insect-repelling compounds, such as azadirachtin. Various analyses, including percentage yield, moisture content, Fourier Transform Infrared Spectroscopy (FTIR), and Ultraviolet-Visible (UV-Vis) Spectroscopy, are conducted to evaluate the neem oil and the candles' properties. Additionally, tests on the candles' melting point, burning rate, scent stability, and candle compression are performed, along with a structured survey to assess consumer perception. FTIR and UV-Vis analyses confirmed the presence of bioactive compounds in the neem oil. The formulated neem-scented candles exhibited moderate effectiveness in repelling mosquitoes, offering a potential alternative to chemical-based repellents. The consumer survey indicated a positive reception towards the neem-infused candles, appreciating their dual functionality as decorative items and mosquito repellents. Neem-scented candles demonstrate potential as an eco-friendly mosquito-repellent solution. The research supports using neem oil as a natural repellent, highlighting its biodegradability and minimal impact on beneficial insects. Future work could focus on optimizing the formulation for enhanced efficacy and exploring other natural additives to improve the candles' performance.
