CBD oil is processed from the hemp plant and is found in all CBD products. “Hemp extract” frequently appears on labels and ingredient lists. After extraction, the oil is used to make CBD oil tinctures, candies, capsules, topical, and vape oils, among other things.
Methods of CBD Extraction
When people discuss how CBD products are created, they primarily refer to the extraction procedure. Carbon dioxide, steam distillation, and hydrocarbon or natural solvents are the most prevalent ways of extracting CBD oil.
CO2 (Carbon Dioxide) Extraction
CO2 extraction separates the CBD oil from the plant material using supercritical carbon dioxide. The term “supercritical” relates to the qualities of CO2 in both a liquid and a gas form, which is why this approach is also referred to as Supercritical Fluid Extraction (SFE).
A series of pressured chambers and pumps exposes CO2 to high pressure and extremely low temperatures during CO2 extraction, resulting in an extracted oil with high CBD levels. The CO3 is then pumped from the first chamber to the second, where the presence of supercritical CO2 causes the hemp in the second chamber to break down, separating the oil from the plant material.
Finally, CO2 and oil are injected into a third chamber simultaneously. The gas dissipates, leaving behind an extract of pure CBD oil. CO2 extraction is the favored method for manufacturing CBD products, even though it needs expensive specialist apparatus. According to one study, it’s incredibly safe and effective at creating large levels of CBD in the resultant oil—up to 92 percent.
CO2 extraction’s precision makes it ideal for generating CBD oil in particular concentrations. Manufacturers may change the solvent and pressure ratios to reach the appropriate CBD concentration.
Distillation using Steam
- As the water heats up, Steam rises into the plant flask, separating the CBD-containing oil vapors.
- The vapors are collected in a tube, condensed into oil and water.
- Once the oil and water mixture has been collected, it is distilled to remove the CBD oil from the water.
Steam distillation is a known and tested method for extracting essential oils that have been used for centuries. However, it is less efficient than CO2 extraction. Steam distillation necessitates substantially more hemp plants, and it’s more difficult to extract precise CBD concentrations using this approach. With this procedure, there is also a level of risk. If the Steam becomes too hot, it might harm the extract and change the chemical characteristics of the cannabinoids it contains.
Extraction of Solvents (Hydrocarbons and Natural Solvents)
Solvent extraction is similar to steam distillation in that it separates the CBD oil from the plant material using a solvent rather than water. As a consequence, the CBD oil and the solvent are mixed. The solvent eventually dissipates, leaving just pure CBD oil. Hydrocarbons or natural solvents are used in solvent extraction.
Solvent extraction is more efficient and less costly than steam distillation. The solvents employed in hydrocarbon extraction (such as naphtha, petroleum, butane, or propane) are, on the other hand, a source of worry. If the solvent residue isn’t completely removed during the evaporation step—which doesn’t usually happen—it might be hazardous and raise one’s cancer risk. Solvent-extracted CBD products have included residues of petroleum or naphtha hydrocarbons in several tests.
Solvent extraction can employ natural solvents like olive oil or ethanol instead of hazardous solvents to prevent poisonous residue. These solvents extract CBD oil just as well as alcohol, but without the risk of harmful residue.
What Is the Best CBD Oil Extraction Method?
Each extraction process has advantages and disadvantages. Although it is the most expensive extraction technique, it consistently yields the highest concentration of CBD, resulting in a high-quality product. It’s also one of the safest extraction procedures because no neurotoxic residue is left behind.
Please find out the extraction process the firm employs when acquiring CBD goods since this might indicate the quality and worth of their products. CO2 extraction products are more costly, but they also tend to be higher quality.
CBD products created using different extraction processes can also be safe and high-quality, but they come with a higher risk. In particular, CBD products prepared using hydrocarbon extraction may include solvent residues.
Confirm that the company employs a third-party lab to analyze the concentration of CBD in their products and the safety of the other components, and their extraction procedure. These test results will be easily available on any respectable manufacturer’s website, with their product packaging, or upon request. The test finding will determine CBD and other cannabinoids (described in milligrams). They’ll also identify any possible impurities and any solvent residue if the product was extracted using a hydrocarbon solvent.
What Happens after You’ve Been Extracted?
The resultant CBD oil is classified as “full-spectrum” after extraction. It indicates that additional cannabinoids, such as Delta 9, CBDA, CBDV, THC, and others, are still present in addition to CBD. As long as the product is made from hemp, the THC content will be less than 0.3 percent (which makes it legal anywhere in the U.S.).
Other helpful constituents from the plant material, including terrenes and amino acids, are also included in full-spectrum CBD oils. Many individuals prefer full-spectrum CBD oil because of the “entourage effect,” many individuals prefer full-spectrum CBD oil. While this effect has not been confirmed, some users feel that when more cannabinoids are present, CBD can engage the end cannabinoid system more efficiently.
Some folks, however, would prefer not to have any THC in their oil, even in very small, legal doses. Some individuals prefer CBD isolates. The extract is cooled and refined into crystalline isolate form to make CBD isolate. It produces a flavorless white powder. CBD isolate is less costly per milligram since it simply includes CBD, has no THC, and has no flavor or odor.
Finally, the CBD oil is mixed with other chemicals to make various CBD products, regardless of whether it is transformed into a CBD isolate or stays full-spectrum.
- CBD oil may be used with natural flavoring, juice, and organic corn syrup to make CBD candy.
- CBD edibles, such as baked goods or chocolates, may be made by combining CBD oil with various components.
- To give CBD capsules bulk, CBD oil is frequently mixed with MCT oil (a coconut oil extract). If the capsule is a soft gel, the shell may also be made of olive oil.
- CBD creams, skin salves, and other topicals can be made by mixing CBD oil with essential oils, shea butter, aloe Vera, and waxes.
