One of the "youngest" methods of extracting essential oils, appeared only in the 1980s. The process uses expensive high-tech equipment. Carbon dioxide at a temperature of 33 degrees and a pressure of 200 atmospheres has an aggregative state, intermediate between gas and liquid, at such a moment it has the properties of a solvent, and the effect of extracting essential oils occurs almost instantly. At the outlet, an essential oil is obtained, which is very close in composition to that which is inside the plant, since the extraction does not cause the influence of damaging factors (pressure and temperature). It does not contain excess impurities, as well as carbon dioxide. The essential oils obtained by the CO2-extraction method are used mainly in luxury perfumery.
