CBD extraction with supercritical CO2
There are many types of CBD-enriched products. oils CBD, CBD cosmetics, e-liquids or even hash de CBD. But do you really know how they are obtained? These solutions are processed after the CBD has been extracted, generally following the precepts ofsupercritical CO2 extraction. It's a complex method, which we'll explain in detail below.

What is CBD extraction with supercritical CO2?
At "standard" temperature and pressure levels, carbon dioxide (CO2) is a gas. It becomes a liquid at 60.4 PSI. When the temperature reaches -78C and the pressure is standard, carbon dioxide CO2 becomes a solid (dry ice).
Conversely, when this gas is heated to a temperature above 31.10°C (critical temperature) and subjected to a pressure of 1,071 psi (critical pressure), it combines the properties of gas and liquid. It then becomes what scientists and experts call: a supercritical liquid.
These supercritical liquids have a variety of properties. They can, for example :
- Passing through somewhat porous solids
- Dissolve materials and act as a solvent
Interesting principles of action when it comes to cannabis. Indeed, by adjusting the supercritical CO2 to your needs, it's much easier to target the cannabinoids you want to extract, obtain or accentuate. Of course, this also depends on the quality of the cannabis plant being processed.
How is CBD extracted using supercritical CO2?
Although complex, the principle ofCBD extraction using supercritical CO2 has been simplified as far as possible. An eight-step decarboxylation process.
-
- 1. An extraction chamber is filled with cannabis trim. Also known as flower of hemp / ground hemp plant.
- 2. A pump redirects into the extraction chamber. When activated, it delivers pressurized carbon dioxide at the optimum temperature.
- 3. CO2 (supercritical carbon dioxide) interacts with cannabis compounds (cannabinoids, terpenes, flavonoids).
- 4. Supercritical CO2 transports theoil cannabis particles through a pressure-release valve to a cyclone separator.
- 5. In the same cyclone separator, the pressure is lower. The CO2 (carbon dioxide) andoil are then observed to separate.
- 6. The CO2 gas rises quietly to the reservoir provided. It can then be reused. Generally speaking, the supercritical CO2 extraction circuit is a closed circuit.
- 7. Theoil cannabis, waxes and hash descend into the separator where they fall into a collection container.
- 8. The resulting substance is then processed into various products, such as the solvent-free, CBD-richoil cannabis.
What are the advantages of supercritical CO2 extraction?
The CBD extraction process using supercritical CO2 has a number of advantages. In the rest of this content, we'll show you why it's used in the production of CBD oils. Oils from hemp which we offer for sale in our CBD oil wholesale boutique.
1. Allows you to create a variety of CBD products
Extracting a CBD concentrate allows you to "personalize" your approach and use CO2-extracted cannabinoids in a variety of products. Wax, CBD oil full / broad spectrum or even shatter and budder... It's entirely possible for brands to indulge their imagination and give free rein to their desire for innovation.
2. Enables the development of new ultra-targeted strains
Another advantage of extracting CBD with supercritical CO2 is the ability to target specific strains. By mastering the oils cbdextraction technique, and by mastering the targeting of cannabinoids, we can accentuate the production of products rich in specific components of the cannabis plant. In the future, we can therefore imagine CBD products specially designed to treat specific ailments or illnesses.
3. Kills bacteria
Opting forCBD extraction with supercritical CO2 ensures that you select an extraction method with antibacterial properties. This means that no strains of microbes, moulds or mites remain in your CBD oil. A natural way of doing things, since the producer avoids the use of potentially harmful chemicals. What's more, the product keeps longer.
4. Improves taste
The different oils CBD products tested don't have the same taste, color or texture? Depending on the extraction method used, butane and other toxic solvents can destroy certain molecules, affecting the taste and even the experience. A product like CBD oil extracted with supercritical CO2 allows you to enjoy a natural, pleasant solution!
5. Downside: Expensive and knowledge-intensive
The only downside here is thatsupercritical CO2 extraction is quite expensive. It's an expensive method, and all employees need to be trained in its use. In other words, you need to invest in qualified personnel and suitable machinery to produce CBD oil in quantity! Industrial production remains profitable, and companies will continue to favor this type of solution.
