Supercritical CO2 extraction (SCFE) is a safe method of efficient botanical extraction using a clean, non-toxic solvent ideal for cannabis, hops and more. Learn how CO2 cannabis extracts are produced and familiarize yourself with the science behind this versatile extraction method. Curious about CO2 extraction? The experts at Honest Marijuana tell you everything you need to know about CO2 cannabis concentrates.
Each of these has individual strengths and weaknesses. A cylinder or a series of cylinders usually made of stainless steel where solutes concentrate after the extraction process. The isolation of cannabinoid crystals via the production of a supersaturated solution, rudimentary liquid-liquid separation, temperature change and solvent removal. This process is often performed under a neutral atmosphere to avoid degradation. A mixture of cannabis oil, water and an emulsifier.
A cylinder that is usually made of stainless steel where plant material is packed and where a solvent is injected to remove solutes from the parent material. The process that uses a solvent i. A product that undergoes minimal refinement—usually only winterization and clarification—that includes all of the major components of cannabis i.
A purified individual cannabinoid at plus percent resulting from a chromatography process. An emulsion that contains micelles that measure within the nanometer range. An apparatus that controls the pressure of the solute in the extraction and collection vessels. A part of a closed-loop extraction system that conducts the solvent phase change and houses the recycled solvent prior to re-injection to the extraction vessel.
Refined Extract or Refined Oil: The product resulting from undertaking the winterization and clarification processes after the initial extraction. This is a cannabinoid-rich oil or sap that is usually yellow to red in color.
The second—or downstream—stage of the extraction process where the target compounds i. Some technologies have the ability to separate the compounds in multiple ways based on molecular weight i.
A refined extraction product that contains high concentrations of acid-form cannabinoids; it is crystalline and usually used for dabbing or vaporizing.
It can also be consumed orally to obtain high dosages of acid-form cannabinoids. A substance of interest in feed material i. In the cannabis industry, the cannabinoids, terpenes, flavonoids, etc. The recovery of the winterizing and clarification solvent with the application of heat and vacuum.
The most common techniques include rotary evaporation and falling-film evaporation. A substance with properties that promote the dissolution of solutes from the parent plant material. The most common examples in the cannabis industry are butane, carbon dioxide and ethanol. A refined extract that contains large amounts of terpenes and a moderate concentration of cannabinoids.
It is usually liquid or sap and commonly used for dabbing or vaporizing. A product that can be derived from a full-spectrum oil or distillate formulation often used in a small vaporizing cartridge or larger vaporizer. Sometimes oil viscosity is manipulated with polyethylene glycol, propylene glycol, alpha bisabolol or medium chain triglycerides. Wax or Crude Extract: The product first obtained from the extraction process. It contains all of the solutes extracted from the plant material i.
Mostly applies to products from carbon dioxide extraction. The process where crude extract is dissolved in ethanol at warmer temperatures i. Long known for its versatility and high efficiencies, CO 2 is commonly used in many types of commercial processing, such as dry cleaning, where it removes dirt without affecting the clothing. CO 2 extraction of botanical material works much the same way.
The CO 2 removes the oil as it passes through the plant, leaving it intact. Remarkably, the plant material will look the same after extraction as before except it no longer contains the oil. With CO 2 extractions, there are no residual components in the extracted material. Consumers prefer products that are made from natural substances, such as CO 2.

The matricin is not degraded to chamazulene. Chamazulene has only one tenth of the anti-inflammatory activity as matricin. CO2 extracts have a minimum shelf life of one year. They should be kept under the same conditions as steam distilled essential oils Unlike the products produced by regular solvents absolutes and concretes the solvent CO2 can be easily and totally removed, just by releasing the pressure in the extraction chamber.
This process, because it happens in a closed chamber, can then collect the most volatile and most fragile fractions of the fragrance and plant.
