CO2 Supercritical Extracts, also known as CO2 Extracts or simply as CO2s, are high quality oils extracted using liquified Carbon Dioxide as the solvent. CO2 Extracts are often preferred to steam distilled essential oils for aromatherapy, beauty, cosmetic and personal care applications because CO2 Extracts retain more of the plant's natural chemical composition and are often considered to be superior in aroma.
When carbon dioxide is pressurized and converted to liquid, it becomes a safe and effective solvent that allows all the desirable active constituents of the botanical to be collected without the risk of heat degradation or exposure to potentially toxic solvents. Once the extraction is complete, the carbon dioxide is allowed to return to its natural gaseous state, leaving behind only the extracted essence of the plant.
CO2 Selects: CO2 Selects are oils that have been extracted using CO2 at lower pressure. CO2 Selects contain only the volatile CO2-soluble components. The heavier waxes, resins, and color compounds are not present in CO2 Selects. The viscosity of CO2 Selects are generally thicker than steam distilled essential oils but are still pourable. CO2 Selects resemble steam distilled essential oils in composition and beneficial applications, however, they may contain more volatile components that are not extracted during steam distillation.
CO2 Totals: CO2 Totals are oils that have been extracted at higher pressure. CO2 Totals contain both volatile and non-volatile CO2 soluble components of the botanical. CO2 Totals contain the essential oil, heavier waxes, fatty acids, resins and color compounds, making the extract very similar to the plant itself.
