What are CO2s?
Best factories also sells Oils extracted by a method using carbon dioxide, known as, CO2’s. This process uses pressurized CO2 carbon dioxide until it becomes a liquid. The liquid carbon dioxide acts as a solvent on the natural plant matter dissolving the essential oil into a liquid carbon dioxide. The CO2 is evaporated back into its gaseous state leaving only essential oil.
Factories label CO2s as essential oils as opposed to absolutes since no trace of harmful solvents remain. Additionally, essential oil using the CO2 method has an advantage over essential oils because none of the constituents of the oil are damaged by heat.
Oils extracted by carbon dioxide are often thicker than essential oil and often smell closer to the aroma of the natural herb and have a more rounded aroma.
