• through a low-energy method, using polysorbate 20 as a surfactant. The formulation presented an average droplet size ranging from 244.6 to 280.4 nm, a polydispersity index of less than 0.25, and a negative zeta potential (−15.7 to −18.6 mV), maintaining stability for 14 days. In the bioassays, fourth

• bicyclogermacrene, valerianol, β-pinene, and sesquirosefuran being the major substances in the essential oil of leaves (81.4%), suggesting a key role of this metabolites in larvicidal activity [113][115]. The oil was extracted using hydrodistillation and incorporated into the nanoemulsion by the low-energy method

• using a low-energy method with sorbitan monooleate 80 and polysorbate 20. The NE presented an average droplet size of 74.5 nm (±1.939) and a polydispersity index of 0.271 (±0.007), remaining physicochemically stable for up to 180 days.
