Supercritical carbon dioxide extraction is a process where carbon dioxide passes through a mixture of interest at a certain temperature and pressure until it reaches an extractor.

Carbon dioxide (CO 2) is the most used supercritical fluid, sometimes modified by co-solvents such as ethanol or methanol. Extraction conditions for supercritical carbon dioxide are above the critical temperature of 31 °C and critical pressure of 74 bar .

Supercritical carbon dioxide is used as the extraction solvent for creation of essential oils and other herbal distillates. [5] Its main advantages over solvents such as hexane and acetone in this process are that it is non-flammable and does not leave toxic residue.
