Wood characteristics Swietenia macrophylla is a rather soft, medium-weight timber. 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]. The product yields were collected at an interval of 25 °C. This study was aimed to determine the characteristic of the mahogany leaf stomata in a polluted environment.
