C02 Oil Extraction vs. Ethanol Etraction
At least once a day we are asked the difference between ethanol and c02 extraction. We offer products made from both ethanol and c02. We tend to like ethanol better as we believe it pulls out more of the beneficial compound of the plant. No solvent is perfect for cannabis extraction in every way. Common perception is that c02 is “safer”. Fact is, there should be next to zero trace of any solvents in the crude oil going into the CBD products you are sourcing, so this is in fact false. Make sure you always ask for a certificate of analysis.
Our bodies naturally produce carbon dioxide when we breathe so it’s considered a “natural” product. The lengthy purification process required to remove co-extracted constituents, such as waxes and plant fats, from the extracted product can take away from the final cannabinoid and terpenoid profile of extracts yielded during supercritical CO2 extraction.
If you are getting a “C02”product from a supplier the first thing you need to ask them is what is the winterization process they use (post processing to condense the cannabinoids and clean out the “impurities”)? People don’t realize that most facilities will take the initial C02 extracted crude and winterize it using ethanol, totally negating the point of C02!
CO2 is nontoxic and CO2 extraction processes do not contribute toward carbon emission increases in our atmosphere.
CO2 extraction doesn’t bring any flammable petroleum-based solvents (like butane) into contact with your medicine. This removes the danger of explosions from the CO2 extraction process as well as potentially harmful petroleum-based butane particles from the final, very fine, concentrated hemp product

Ethanol is effective, efficient, and safe to handle. It’s commonly used as a food preservative and additive, found in everything from the cream filling in your donut to the glass of wine you enjoy after work. Ethanol crude oil will typically have an initial darker composition than C02 and thats because ethanol’s polarity. A polar solvent [such as ethanol] will readily mix with water and dissolve water soluble molecules. Chlorophyll is one of those compounds which will easily co-extract when using ethanol as a solvent. So like we said earlier, its pulling out more of the plant material. When you are looking for a full spectrum product, thats not necessarily a bad thing. The poo pooing of the darker product has more to do with appearance and marketing than medicinal value. These water soluble components of the hemp plant have medicinal value. A good lab can overcome this with post processing techniques.
Ethanol extraction can eliminate the need for a dewax or winterization. People don’t realize that most labs post process their c02 extraction in ethanol baths anyway (winterization)
Can create superior full spectrum hemp products
Because ethanol is what is called a “polar” solvent, it will be more hydrotropic, meaning it will want to bind to the water soluble components of the plant.
