The CBD in the plant must be extracted in order to make CBD products that are flooding the health, wellness, and beauty markets. Not all CBD extraction methods are created equal; some are much safer and more efficient than others. We will discuss solvent extraction, oil extraction, and carbon dioxide extraction, as well as the pros and cons of each. These are the most common and generally accepted methods for extracting CBD from the cannabis plant, though there are many others.
Full Spectrum CBD Distillate, the various compounds found in the Cannabis plant, give it a wide range of potential applications. Cannabidiol, or CBD for short, is one such chemical compound and, after THC (Tetrahydrocannabinol), the most abundant cannabinoid in cannabis. However, CBD isolated from hemp plants is devoid of THC and has none of the psychoactive effects of THC extractions from conventional cannabis. Instead, it is applied to help with things like pain management, muscle recuperation, anxiety reduction, and skin rejuvenation.
Extraction with a Solvent
Solvent extraction, as the name suggests, involves the use of solvents to isolate CBD oil from the plant. CBD oil is made by passing a liquid solvent through decarboxylated plant material. The cannabinoid and terpene content of the plant is extracted and transported by this process. When the solvent is gone, all that's left is pure CBD oil. One of the most effective and affordable methods of extraction is this one, which can be used with either hydrocarbons or natural solvents.
However, there are numerous disadvantages associated with this CBD extraction process.
Hydrocarbons, for one, are highly flammable chemicals, making their use extremely risky. Since these solvents pose a significant risk of injury if used improperly, their use is restricted to laboratories staffed by trained professionals.
Butane, propane, naphtha, and petroleum are all examples of hydrocarbons that pose a fire hazard and also have negative health effects on consumers. The risk of cancer increases if even a small amount of these toxins remains in the body. Solvent extraction is not always precise, so care must be taken to ensure that all of these chemicals are removed during the evaporation process. Some CBD products that used a solvent extraction method have been shown in studies to have trace amounts of hydrocarbon residue.
The CBD extraction process also removes waxes, chlorophyll, and other beneficial components of the plant. This process can make the CBD oil thicker, darker, and of lower quality. Because of these drawbacks, most reputable CBD manufacturers avoid using this extraction technique.
Extraction of Oil
This method of CBD extraction is nearly identical to the solvent extraction described above, with the exception that oil (typically olive oil) is used instead of water. Instead of soaking the decarboxylated plant in hydrocarbons, it is heated in olive oil for a few hours. Cannabidiol (CBD) and the other cannabinoids in the plant combine with the oil's fatty acids during this time. The remaining plant matter can be filtered out of the oil after it has cooled, leaving CBD-infused oil.
Olive oil, in contrast to hydrocarbons, is a natural solvent that leaves no toxic residue after the extraction process is complete. If you've ever wondered how to extract CBD oil, you can do it yourself. Olive oil extraction is a viable at-home method for those with basic kitchen skills and an interest in experimenting.
When compared to synthetic solvents, natural solvents are just as efficient at separating CBD oil from the plant matter. Chlorophyll, which is extracted by some natural solvents, gives the oil a bitter taste if consumed. Chlorophyll removal is unnecessary if CBD will be ingested in a capsule or applied topically. Many CBD products, however, are designed to be ingested or inhaled, and doing so after chlorophyll has been removed can be unpleasant for the consumer. However, natural solvents' resistance to evaporation is the biggest problem of all. Since this is not as efficient as other methods of CBD extraction, the resulting oil will be weaker.
Taking Out the CO2
CO2 extraction is currently the most effective method for obtaining high-quality CBD oil. Although official regulatory guidelines have not yet been established for the CBD industry, CO2 extraction is quickly becoming the standard among reputable CBD brands.
Supercritical CO2 extraction, subcritical CO2 extraction, and intermediate CO2 extraction are the three main methods. The quantity and size of plant molecules extracted, as well as the intensity of the extraction process, are what set them apart. Supercritical CBD extraction yields the purest oil, but subcritical and intermediate methods still yield Full Spectrum CBD Distillate. This is why Imperial CBD Extraction uses it the most out of the three methods.
In the supercritical method, carbon dioxide (CO2) is used as the solvent, and it is brought into a "supercritical state" by applying extremely low temperatures and special equipment so that it behaves like both a liquid and a gas. For the purpose of dissolving terpenes and cannabinoids at their respective solubilities, the CO2 is pumped through the plant at multiple temperatures and at varying angles in a process called fractionation. Since neither the plant nor its compounds are harmed by the presence of CO2, extraction is maximized. Since no additives that could contaminate the oil or pose health risks are needed, this extraction method is the safest option. Since CO2 can be recycled, this extraction method is the most cost-effective for businesses that manufacture CBD products in bulk. However, this technique is an industrial process, and due to the cost of the necessary equipment, it is not accessible to anyone other than those who are serious about producing CBD products.
Following CBD extraction, what steps are taken?
The oil that is produced after CBD extraction looks very similar to crude oil, so the question arises: how is CBD extracted? The next steps in the process, winterization and filtration, result in Full Spectrum CBD Distillate. Nearly all of the cannabinoids found in cannabis are present in Full Spectrum CBD Distillate. However, CBD oil derived from this plant will only contain trace amounts of the THC (hence being non-psychoactive), as hemp has a negligible THC content—less than 0.3% dry weight.
Winterization
One of the most important steps in making CBD suitable for sale is the winterization process. After the extraction process, a crude oil-like oil is produced; this oil is then winterized to become Full Spectrum CBD Distillate. It accomplishes this by eliminating lipids, which are fatty acids responsible for the extract's waxier, softer, and cloudier characteristics. Since lipids have a higher melting point than the extract, they must be removed to prevent dilution and loss of flavor in the final product. During winterization, the extract oil is mixed with another solvent like ethanol and exposed to extremely low temperatures. Lipids will rise to the surface because they are less soluble in the ultra-cold solvent. Once this occurs, the extract's lipids can be filtered out.
What happens during winterization is affected not only by the extraction process, but by it in general. Therefore, the amount of plant fats extracted will vary depending on whether cold ethanol (natural solvent extraction), BHO extraction (hydrocarbon extraction), or CO2 extraction is used. While cold ethanol extraction results in the least amount of fat in the final extract, CO2 extraction is the gold standard for maximizing plant fat removal.
A word about Analytical Verification Documents
A COA, or Certification of Analysis, is a document issued by a qualified testing facility that details all of the ingredients in the product for sale. Cannabinoids, terpenes, microbiological levels, and potential contaminants like pesticides, heavy metals, or solvent residue should all be listed in a CBD's Certificate of Analysis. A certificate of analysis (COA) is crucial because it attests to the product's dependability and proves the company's product is open and honest. It can be difficult for consumers to evaluate the quality of a product on the market, especially if it is part of a new industry that has not yet been subjected to extensive regulation. Obtaining a Certificate of Authenticity (COA) will equip you with the knowledge to make an educated purchase, which is essential for avoiding any kind of deception. Certificates of Analysis (COAs) are available for all products sold by Imperial CBD Extraction.
No matter what you prefer, the most important thing is to be an educated consumer who knows what they're buying. The majority of legitimate CBD producers will gladly provide copies of their COAs. But obtaining a COA is not always a simple process. It may be included with your order as a QR code you can scan to access the COA, or you may need to contact the company directly to get it. If it's not obvious where to find it, don't be shy about contacting the company and asking for it. You have the right to know what goes into the things you put in your body.
