While it’s true that hemp-derived CBD doesn’t have the same psychoactive effects as THC, that doesn’t mean it’s completely free of THC. According to federal law, hemp plants and hemp-derived products are legally permitted to contain up to 0.3% THC.
It’s incredibly easy to measure CBD isolate dosages, as there’s nothing else to account for aside from the pure CBD. With other CBD-based products, such as broad-spectrum and full-spectrum CBD oil, the cannabinoid is mixed with other cannabinoids, making it more difficult at times to quantify the exact amount of CBD that is being consumed.
What is CBD isolate?
There are various processes used to produce CBD isolate from industrial hemp extracts, such as supercritical carbon dioxide (CO2) or ethanol-based extractions. The same extraction methods can also be used as a starting point for the production of THC isolate as well, but typically with marijuana plants instead of industrial hemp. To create an isolate, a number of components are removed from the plant, including other cannabinoids, terpenes, and flavonoids, as well as fats, lipids, and other compounds. After that, the CBD compound is separated from the rest of the extraction through a series of chemical washing and separation processes.
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.
While you might not know what to do with a pile of odorless CBD isolate powder at first, there are a number of different ways to consume CBD isolate. Here are some of the most common delivery routes:
CBD Isolate is 99% pure Cannabidiol derived entirely from hemp oil that was extracted from industrial hemp. Our isolate comes in crystalline (powdered) form making it extremely easy to work with as an ingredient.
CBD isolate has already been activated (decarboxylated), which means that it doesn’t need to be heated prior to use. This gives isolate more versatility than other CBD extracts. CBD Isolate can be ingested, taken sublingually, or mixed with other ingredients.
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.
Once winterization has been completed it is necessary to now quickly filter those fats and waxes we coagulated from the miscella. A filter press is used with the assistance of a vacuum pump to pull the miscella mixture through a series of filter plates. Fats, waxes, etc are collected in one vessel and the desired miscella in another.
Steps on How To Make CBD Isolate
Now that our extract has been winterized, filtered and decarbed, we can perform distillation. There are short path and wiped film distillation apparatuses on the market, for the sake of this article we will use wiped film distillation.
To make any concentrate you first have to extract. Manufacturers can use either a hydrocarbon solvent, like butane or propane, or ethanol solvent. Typically, we see ethanol used for the production of CBD isolate often with the use of a larger commercial extraction system – like a centrifuge. Smaller extraction systems can be used, it just depends on your throughput goals.
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’).
