Abstract: A Process for Preparing a Synergistic Herbal Mosquito-Repellent Roll-On Formulation The present invention relates to a process for preparing a herbal mosquito- repellent roll-on formulation comprising Neem leaf extract, Tulsi leaf extract, Mint leaf extract, Marigold flower extract and Eucalyptus globulus oil. The process comprises separately extracting the botanical materials using approximately 60% v/v ethanol-water, controlled filtration, vacuum concentration at 38-40°C, standardization to approximately 20±2% w/w extract solids, blending the extracts at a 3:2:2:1 ratio, followed by controlled incorporation of 1.0-2.0% w/w Eucalyptus oil and 1.0-3.0% w/w Polysorbate 20, homogenization at 1,500-2,500 rpm for 10-15 minutes and roll-on filling. The optimized formulation comprises approximately 3.0%, 2.0%, 2.0%, 1.0% and 1.5% w/w of Neem, Tulsi, Mint, Marigold and Eucalyptus, respectively, and is configured to provide prolonged mosquito repellency and an experimentally determinable synergistic effect.
