Nevertheless, the oil organoleptic char- 12 acteristics as odor, viscosity, texture, and susceptibility to oxidation limit the in natura oil 13 topical application. Therefore, the aim of this study was the development of nanoemul- 14 sions containing moringa oil (MO) as a nanotechnological approach to enable a suitable 15 topical use. Methods: The Quality by Design (QbD) approach by Design of Experiments 16 (DoE) tool was used to determine the required HLB value (rHLB) of MO and develop the 17 nanoemulsion. Subsequently nanoemulsion was characterized by hydrodynamic droplet 18 size, polydispersity index, and zeta potential, followed by a preliminary stability study 19 under different storage conditions (4 ± 2 °C, 25 ± 2 °C, 45 ± 2 °C). Results: The required 20 HLB identified through DoE was 12.27. The nanoemulsion obtained by the QbD strategy 21 was composed by 10% of MO, 12% surfactant mixture (Kolliphor® RH 40 and Span® 80), 22 and 78% water. This composition produced a nanoemulsion with an average droplet size 23 of 89.94 ± 5.34 d.nm, a polydispersity index (PdI) of 0.14 ± 0.02, and a zeta potential of - 24 9.55 ± 0.195 mV. The final formulation exhibited typical characteristics of nanoemulsified 25 systems and adequate physicochemical stability for 90 days, demonstrating a promising 26 topical product. Conclusions: These results indicate the successful development and pre- 27 liminary characterization and stability for a nanoemulsion containing MO, paving the 28 way for its further evaluation and use on wound healing.
