The Advantages of Cryogenic Ethanol Extraction

The Advantages of Cryogenic Ethanol Extraction

Botanical Solutions is built on the platform of innovation and forward motion. That’s why we chose to use the cryogenic ethanol extraction method. But before we jump into the technology itself, let’s get up to speed with what exactly ethanol is. 

My first exposure to ethanol was way back in the late 1970s when I was in a fraternity in college. Our fraternity had a party with a bowl of punch that was made with grain alcohol. Grain alcohol is ethyl alcohol, otherwise known as ethanol. Ethanol is a colorless, flammable liquid with a piquant taste, and acts as the intoxicating ingredient in various liquors. Of course, ethanol has other uses as a solvent and a fuel. It is made from various forms of grains, but it is most often made from corn, possibly the most ubiquitous grain.

Ethanol is commonly used for plant extractions. It is a proven method in producing extraordinarily high-quality CBD oil, as well as other cannabinoid oils. Ethanol can be used effectively in dissolving hydrophilic substances, those tending to mix with, dissolve in, or be wetted by water. However, it is a solvent that is equally effective in dissolving lipophilic substances, which tend to combine with or dissolve in lipids or fats.

Many producers in our industry are under the distinct impression that CO2 is the cleanest way to extract. However, even labs that have embraced and advertise CO2 extraction methods still use ethanol for winterization. Claims that the best extraction is solely CO2 can be misleading. 

We chose the cryogenic ethanol extraction method because it provides us with the best of both worlds. It enables us to extract high quality CBD crude, distillates, and isolates complemented by the safety of CO2 extraction. Additionally, top cryogenic ethanol extraction equipment is the most efficient on the market today. For example, our lab can process up to 15,000lbs of biomass in a 24-hour period. When compared to CO2 and hydrocarbon extraction methods, ethanol extraction is safer, more scalable and offers superior functionality.

As pioneers of modernizing the CBD industry, we feel the responsibility to correct the misconception that ethanol is not a clean method of extraction. If done properly, all the ethanol used in the extraction process is purged. To confirm purity, all end products are signed off by a Certificate of Analysis (COA) done by an independent lab, which we make available to our customers in their online portal. The bottom line is that ethanol is a clean and dependable extraction method to deliver a higher quality end-product.

At Botanical Solutions, we pride ourselves on our state-of-the-art cryogenic ethanol extraction equipment. Through leading edge technology we’re able to produce extraordinarily high-quality crudes, distillates, and isolates. Our team looks forward to showing farmers, wholesalers, and CBD manufacturers alike, the wonderful advantages of cryogenic ethanol extraction done right.
