This study presents the development of a natural mosquito repellent spray formulated with lemon and eucalyptus essential oils. Key physicochemical properties—including pH, viscosity, and stability—were evaluated to ensure skin compatibility and formulation consistency. The spray demonstrated a neutral pH of 7.0, smooth flow characteristics (approximately 1.3 seconds through the test nozzle), and remained stable under varying temperature conditions. Utilizing biodegradable, non-toxic components as an alternative to conventional chemical repellents such as DEET, the formulation offers a safer and environmentally friendly approach to mosquito protection.
