What are CO2s?
The Aromatherapy and
Essential Oil Centre also sells Oils extracted by a method using carbon
dioxide, known as, CO2’s. This process uses pressurised 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.
We 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.
