What Does CO2 Extraction Mean?
In the pursuit for optimal purity, high terpenes, and superior quality, CO2 extraction of cannabis oil and concentrates has become commonplace. CO2 extraction, known as supercritical fluid extraction (SFE), uses carbon dioxide (CO2) heat compressed to a critical point.
CO2 can reach its critical point at 90 degrees Fahrenheit, which is cool enough that the cannabis plant’s terpenes and cannabinoids are not damaged during the extraction process. The CO2 is compressed into a cold liquid state and then passed through cannabis. As the liquefied CO2 passes through the cannabis, it extracts the plant’s trichome and terpene-rich oils and waxes. It quickly penetrates the cannabis’ trichomes to dissolve all the available oils for extraction.
