ABSTRACT
Nanoemulsions were prepared from selected blends of essential oils of mentha -turmeric and mentha – dill. The average droplet diameter for two emulsions was 12.29 nm and 21.65 nm as measured by diffractive laser scattering (DLS). The polydispersity index for the developed emulsions was found to be 0.2 which indicated narrow size distribution of particles and monodisperse nature of nanoemulsions. Further, the bio efficacy of the developed formulations was evaluated by Contact Toxicity Bioassay. At 02.0 mg/mL concentration of the prepared emulsions, 65% and 68% mortality of R. dominica adults was recorded after 72 hours of exposure. Overall, the study reveal a strong possibility of using essential oil (from edible plants) based nano-formulation for achieving food safety.
