The technological applications of nanoemulsions have increasingly been used in various applications due to their characteristic properties, small droplet size (in the range 20-200 nm) with high interfacial area, transparent or translucent appearance, high solubilization capacity, low viscosity, and high kinetic stability sedimentation, flocculation, and in some cases, the coalescence [1-3]. Due to the past indiscriminate felling, the mahogany of this species is not any more commercialized, it is available only rarely and in limited quantities, mostly coming from small African plantations; presently, the mahogany utilized comes almost exclusively from the Swietenia macrophylla, native to continental America, from Mexico to Bolivia and Brazil.
