How CBD Isolate Is Made

CBD isolate is made from CBD-rich plants such as hemp, Cannatonic, and Charlotte’s Web. These strains of cannabis contain low amounts of THC and are ideal for extracting CBD isolate. When one of these cannabis plants reach maturity, the plant is harvested and subjected to some form of extraction such as CO2 extraction, Ice Water extraction, Ethanol extraction or Butane extraction. The extraction process will separate the cannabidiol or CBD from all other compounds such as THC, terpenes, flavonoids, and trichomes. At the end of the extraction process, you will be left with pure CBD concentration.

The CBD concentration is refined a little bit more through a process known as Winterization. It removes the excess waxes and leaves behind 100% pure CBD concentration known as CBD isolate. Isolate is the purest form of CBD on the market. When you are buying CBD isolate for your pets, you should buy it from a trusted supplier. The extraction method isn’t easy. It takes a lot of hard work and time. Not every supplier is good at this process. Do your research and buy from a trusted source to get the maximum health benefits for your pet.


Extraction is the only way to get CBD out of the hemp plant. However, to get cannabidiol isolate, the extraction process is a bit different and a bit more detailed. The extraction process starts off like any other extraction process used to acquire cannabidiol. Once the initial extraction has taken place, the concentration acquired is still full of the different compounds contained in the plant.

To acquire pure CBD isolate, the concentrate is passed through an extra purifying process. This process includes filtering out all unwanted plant materials from the extract. After filtration, the oil extracted is subjected to another extraction process known as “winterization” where all remaining plant materials and waxes are removed.

At the end of the process, what you are left with is a highly refined, white powder that’s 99 percent cannabidiol.

2 Common Extraction Processes 

There are two common ways to extract CBD isolate.

  1. CO2
  2. Ethanol

Natural Methods

CO2 Extraction: The Most Common Approach 

Obviously, the main way this method works involves the use of CO2. This chemical has the power to extract other chemicals, such as separating CBD from THC. The Carbon Dioxide is put under very high pressure while also being at an extremely cold temperature which allows it to extract CBD oil from THC. This is not a do-it-at-home method by any means. Expensive equipment and operator payroll costs for make them prohibitively expensive for many startups, but are still the most effective way to ensure all THC is removed. 

Ethanol Extraction: An Affordable, Aggressive Solution

Alcohol can also be used to separate THC from CBD. This usually results in a mixture that is best for vaping. This method is effective for dissolving the molecular bonds of THC in the initial pressing, while leaving pure CBD molecules in tact. The process also destroys plant waxes, which may have synergistic health benefits when used in conjunction with CBD.
