In this example, most of the molecule is nonpolar (the long C-H tail) with just a small part at the right end being polar. Isopropyl palmitate should be stored in well-closed containers and protected from light. Penetrating oils have a low viscosity that enables them to seep between cracks and narrow spaces, leaving an oil film inside spaces. The oil extraction by the Soxhlet method provides greater amount of oil compared to other methods, because the sample remains in contact with the solvent by evaporation and condensation.
