Co2 extraction Method

Co2 extraction Method

Carbon dioxide extraction is a relatively new process used to extract the essence of the plant. CO2 extraction is a process that uses pressurized carbon dioxide to pull the desired phytochemicals (such as hemp) from a plant. CO2 at certain temperatures and pressures acts like a solvent, without the dangers of actually being one. When a certain amount of pressure is applied to CO2 (carbon dioxide) this gas turns into liquid. This liquid CO2 can be used as a very inert, safe, “liquid solvent.”

CO2 extraction is already a standard extraction method for the food, dry cleaning and herbal supplement industries. It is a common food additive as well.

These potent Co2 extracts are wonderful for cosmetics and pharmaceuticals. The calendula extracts, for example, in a dosage of 2 grams extract to 1000 grams ointment is effective for its anti-inflammatory and anti-microbial activity. 

CO2 extracts have a minimum shelf life of one year. They should be kept under the same conditions as steam distilled essential oils, that is in a cool, dark place, in full glass containers.
