What isCBD oil?
CBDoil is a product obtained by working on CBD flower . The quality of oil depends on the extraction method used. CBDoil is then packaged in 5, 10 or 30ml bottles before being offered for sale. CBDoil can be taken sublingually, by placing a few drops under the tongue, so that the benefits are felt within 5 to 20 minutes.
When the product is full spectrum, it promotes the entourage effect, offering an even more interesting consumer experience. A pleasant, easy-to-take product, which is legal as long as it contains less than 0.2% THC, the psychotropic molecule of the cannabis plant.
CBDoil can be obtained using several extraction methods. Here, we tell you all about subcritical CO2 extraction.
What is subcritical CO2 extraction?
Although subcritical CO2 extraction is not as common as supercritical extraction, it remains a popular method for CBD producers and the industry in general. In fact, it ensures higher yields and a less time-consuming process.
Basically,subcritical CO2 extraction is a similar process to supercritical extraction, but operates at lower temperatures and pressures. However, subcritical CO2 extraction tends to produce a thinner, less consistent oil . A bit like molasses.
What are the advantages of CBD extraction with subcritical CO2?
The main advantage of using cannabis extract extracted with CO2 is the lack of additional solvents or excessively high temperatures. CO2 is considered an "ecological solvent". The use of carbon dioxide results in cleaner, healthier products.
CO2 is a natural ingredient that appears in the breathing process during exhalation. Unlike solvents such as butane, supercritical CO2 leaves no toxic residues, traces of alcohol or other chemical active ingredients. It is also recyclable, making it economical.
Other benefits of CO2 extraction include:
-
- An inert, non-flammable and above all non-toxic end product
- CO2 has moderate critical points
- Solvent strength can be fine-tuned by adjusting the compound density
- It yields large quantities of pure extracts.
- CO2 enters its supercritical state at temperatures close to room temperature, making it a perfect solvent for extracting volatile compounds.
Finally, thesubcritical CO2 extraction method involves no heating elements, preserving the widest range of different cannabinoids, cannabinoid acid forms such as CBDa, CBGa, CBNa, terpenes, vitamins, fatty acids. Only a subcritical CO2 extract can be called the real oil from hemp .
Why isn't the subcritical method widely used?
Subcritical CO2 is the most expensive and time-consuming method of extracting CBD. Extraction times can be longer and yields are generally lower. This is why many companies prefer supercritical CO2 extraction. This faster method produces a thicker oil with a consistency similar to peanut butter.
Indeed, higher temperatures and pressure can extract larger compounds, such as chlorophyll, waxes and omega-3 and 6 fatty acids. The product then goes through the wintering process, which eliminates these substances, leaving behind the filteredCBD oil.
Why choose oils CBD extracted with CO2?
CO2 extraction takes advantage of CO2's ability to extract as many of the plant's desired compounds as possible. This makes CO2-extracted CBDoil a more "complete" product, as it makes the most of the phytocannabinoids contained in the cannabis plant. A growing number of researchers and experts are recommending these solutions, believing they would provide better results than isolates.
WhileCO2 extraction makes oils CBD more expensive than other methods, bear in mind that the investment is on both sides. The manufacturer invests a lot of money in these technologies in order to offer consumers a more pleasant, healthier solution. Ultimately, this drives up prices, especially as staff must also be trained and competent.
