While consuming CBD isolate might sound like a great approach, keep in mind that there is also a key disadvantage of isolating CBD from other cannabis compounds. Research has shown that the combination of cannabinoids and terpenes generates an entourage effect, a synergistic interaction that boosts the individual effects of each compound involved. Stripping away all the other cannabinoids prevents you from experiencing the potential benefits of the entourage effect.
When shopping for CBD isolate, it’s important to look for products from reputable companies that are lab-tested by a third party. This should ensure that your isolate doesn’t contain any THC, additional plant materials, or other impurities.
How to use CBD isolate
CBD isolate is a crystalline solid or powder that contains 99% pure CBD. A traditional extraction process removes all the active compounds from the cannabis plant. Then, a refining process that strips away all other phytocannabinoids, including THC, and any plant matter. What remains is the CBD chemical compound in its purest form.
Following the mainstream emergence of cannabidiol (CBD) products, there’s a compelling option out there for those who want to experience the potential therapeutic effects of CBD without even the smallest trace of THC. It may not receive the same amount of hype as CBD lattes, infused cookies, or other CBD products, but CBD isolate is actually one of the most distinct and versatile forms of CBD on the market.
For topicals, mix the CBD isolate with moisturizing oils or lotions and apply it to the area of your skin you’d like to treat. You can also buy topicals that contain CBD isolate.
In order to achieve optimal CBD content, decarboxylation is a critical step prior to distillation. The process of decarboxylation is to remove carboxylic acid and CO2 from cannabinoids present in the cannabis extract. Converting the acidic cannabinoid (CBDa) to its neutral form (CBD) ensures the end product contains all of the several benefits the cannabinoid has to offer. Furthermore, failure to remove CO2 from the extract will also affect the ability to properly form a vacuum in your distillation apparatus. The decarboxylation process is achieved through the application of heat in a reactionary vessel.
This crystallization process is started by putting the CBD oil into a large vat, or reactionary vessel, with a stirring attachment. The mixture is heated while constantly being stirred. Then, the temperature is lowered and the rate of stirring is slowed down. Once the mixture has cooled and nucleation starts to occur (the initial stages of crystallization), the stirring rate is drastically increased, which causes the crystals to separate from the solution. After this, the crystals are rinsed with pentane, or another chemical solvent, to remove any remaining unwanted impurities.
Step 3: Filtration
Making CBD isolate requires more steps than creating a CBD oil, as you have to remove every other element, such as phospholipids and flavors, from the product. While the process is more complex and requires additional equipment, it creates a totally pure end product that is free of anything besides CBD.
CBD isolate is 99% pure CBD, often in the form of a white powder that can be mixed into drinks or taken sublingually. This option is often popular among people who are just beginning to explore the use of cannabis or hemp derived products or looking to avoid the euphoric high associated with THC. It is also a great option for people who want hyper-accurate doses of CBD and the flexibility to create their own customized mixtures in their preferred carrier oil or liquid.
While under vacuum, the extract is loaded into the feed tank where it passes over a heated rotating plate. From there, the heated oil then enters a secondary vessel where there are spinning wipers and a thin film is created around the heated, jacketed vessel. A long condensing coil in the middle of the vessel, cooled with recirculating fluid, recondenses the vapors back into liquid form. Receiving vessels then collect the CBD (known as ‘main body’) from the terpenes, volatiles and high boiling point cannabinoids (known as ‘heads’ and ‘tails’).
