Graphical Abstract
  • determined the hydrophilic–lipophilic equilibrium ratio of the nanoemulsion. It was shown to have an adequate droplet size (173.60 nm) with excellent homogeneity (polydispersity index 0.200). The anti-inflammatory activity of the nanoemulsion was evaluated by the carrageenan-induced paw edema method. Finally
  • ]. Despite these variations, the compositional profiles remain comparable, underscoring the distinctive chemical characteristics of the oil studied. Preparation of nanoemulsions, required hydrophilic–lipophilic balance, droplet size, zeta potential, and shelf stability The development of a nanoemulsion
  • requires the determination of key formulation parameters, including the required hydrophilic–lipophilic balance (HLBr), droplet size, and polydispersity index (PDI) [42][43][44]. In this study, the Acrocomia aculeata oil nanoemulsion (AANE) exhibited a uniform droplet size distribution and a stable PDI
