To infuse your isolated CBD with a carrier oil, you’ll need to utilize the double boiling method. The double boiling method is a heat control technique used in cooking that allows you to blend ingredients without exposing them to high temperatures.

How to make CBD oil from Isolate
While CBD is excellent as a pure isolate powder, the one downside is that it lacks some of the other beneficial compounds found in the hemp plant. Full spectrum CBD contains a variety of helpful cannabinoids, terpenes, and other organic elements. CBD isolate has perks of its own, but full spectrum CBD provides you with more of hemp’s benefits – the way nature intended.
CBD is so popular as a pure isolate because isolates have a much broader range of use, including the ability to make CBD oil from isolate. Making your own CBD Oil is easier than you’d expect, and with a pure isolate, you are already halfway there.
CBD Isolate vs Full Spectrum CBD
While CBD oils contain a mixture of plant compounds and oils, isolates are the purest form of a cannabinoid. CBD, CBN, CBG, and other cannabinoids found in hemp can be isolated through an extraction process.
Just as important as where the oil is extracted is how it is extracted, and there are multiple ways to target chemical compounds found in cannabis. Hemp producers employ a variety of extraction methods, including alcohol, supercritical CO2, and butane extraction to remove the therapeutic compounds found in hemp plants. Each method caters to a varying yield, quality, and purity of hemp-derived CBD.
Hemp seed oil is oil extracted from the hemp seed specifically, which contains no CBD. While it may have some health benefits, including diet and skin care, any benefit derived from CBD will not be present in hemp seed oil. You may find that extractors cut their extract with this oil to help dilute the extract, it will give the tincture a more earthy flavor but as stated does not add any additional CBD to the mixture.
How Are Hemp Oil and CBD Oil Extracted?
Three of the more commonly confused and conflated terms in hemp extraction are hemp seed oil, hemp oil, and CBD oil. Let’s explore the key differences:
Where Does Hemp Oil Come From?
Many people prefer CBD isolate due to its neutral flavor and taste, which makes it easy to add to food, drinks, and topicals. Extraction methods remove every other compound including THC. Individuals who don’t want to risk consuming THC or failing a drug test will often look for CBD isolates.
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’).
Depending on what end product you’re trying to make you may prefer to use a CBD isolate powder when manufacturing lotions, edibles, beverages, etc. In order to make a powder you are simply taking the CBD isolate crystals and grinding them down into a powder-like substance.
Winterization is the process of removing the fats, waxes and chlorophyll from the extract. Not removing these will lower the percentage and purity of the targeted CBD compound we are trying to capture. To achieve winterization you are essentially cooling down the extract to sub-zero temperatures with a solvent. Then, maintaining that chilled environment for a period of time in order for the lipids (fats and waxes) to coagulate and separate from the crude oil – now termed ‘miscella’.
Step 4: Decarboxylation
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.
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.
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.
Step 6: Crystallization
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.
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.
