Due to the many benefits of Cannabidiol (CBD), people are using CBD oil as a natural alternative for pain relievers, acne removal, and other medication. Although the CBD comes from cannabis plants like marijuana and hemp, it won’t give you that ‘high’ feeling from THC compounds. That’s why most states allow the manufacture and sale of CBD oil via tinctures, capsules, or edibles.

However, to get the most from the CBD products, CBD oil extraction first occurs. This means turning the CBD compounds into oil form through the following:
1. Ethanol Extraction
Considered as one of the best ways to make CBD oil, ethanol extraction can create highly concentrated and pure CBD oil. With this way of making CBD oil, you can achieve a 99% purity. In this method, you’ll introduce the ethanol to the hemp plant.
To make the process produce higher purity of CBD oil, you can use cannabis oil tech like Oil and Ethanol Recovery System – Batch (OERS-B) or Oil & Ethanol Recovery System – Continuous. These extraction equipment are safe, advanced, and automated. As a result, you can efficiently extract CBD oil with improved purity.
During the process, you’re stripping the cannabinoids from dripping condensed ethanol to the packed hemp. This process is also known as the Soxhlet technique. But to retain the purity of the cannabinoids, you can do this under supercooled or room temperatures.
When using ethanol extraction, you can do it under cold or warm conditions. So wherever you are, you can use this method to make CBD oil.
2. Carbon Dioxide (CO2)
Another way to make CBD oil is through a Carbon Dioxide extraction. As its name suggests, pressurized carbon dioxide or CO2 is a vital element in this process. With CO2, you can use it as a ‘tunable’ and versatile solvent because you can specify the pressure range and temperature.
What’s more, by CO2 extraction, you can make CBD oil without toxic by-products. As a result, you can make a clean and premium quality CBD oil. That’s why CO2 extraction is famous not only for CBD oil production but as well as other food and herbal supplement industries.
Moreover, CO2 extraction has its standard method, too, which is known as the supercritical CO2 extraction. This extraction method uses the fluid state of the CO2 in its critical temperature and pressure. So when you increase the temperature and pressure of the CO2, it changes into a fluid.
Then, the supercritical fluid goes into a chamber where the raw hemp is. When this happens, trichomes’ membranes dissolve, turning them into active compounds. Afterwhich, you now have an amber-colored CBD oil that you can soon vaporize or turn to tinctures.
3. Lipid Extraction
Another way to make CBD oil is through lipid extraction. Although it’s not as popular as CO2 extraction, you can use it as an alternative to ethanol extraction. Instead of using ethanol as a solvent, you can use olive or coconut oil as the lipid in this process. The fatty acid or the lipid absorbs the cannabinoids from the hemp.
With this method, the hemp should first undergo a decarboxylation process. It releases carbon dioxide after it removes the carboxyl group from the molecules or cannabinoids. Then the decarboxylation process converts these inactive groups to become active cannabinoids.
To activate the cannabinoids, you need an hour of 248 ℉ to heat the hemp. Afterwhich, you can now add the oil to the hemp and leave them for two hours at 212 ℉.
Lastly, you can now seal the CBD oil after the process in a cool, dark place.
If you think you’re done with making your own CBD oil after one process, well, you may be right. However, the end-product may still have some fats, waxes, and lipids, depending on the type of extraction method you’ve used. That’s why you may need to apply winterization as your finishing touch.
By doing so, you can ensure a highly pure CBD oil that will satisfy your customers. To filter out the unwanted materials, you can put your CBD oil extract into an ethanol wash. With a sub-zero temperature, the lipids, terpenes, and waxes separate from the CBD oil extract.
As a result, your CBD oil extract will not have a different taste and smoothness from the unwanted materials you’ve used.
Now that you know how CBD oil production works, you can make your own as well. As long as you do each extraction properly, you can create your own version of CBD oil. At the very least, you’ll have an idea of how CBD manufacturers create their CBD oil. By knowing such processes, you know which produces high-quality and purer CBD oil.
From CO2, ethanol, or lipid extraction, you can choose which method your own CBD oil should undergo. But the most important part is the winterization process so that the quality of the CBD oil extract is not tainted with other materials.
