Our Extraction Process
Our focus at Leafwell is delivering the best quality products to all of our customers. Given this, we utilize both CO2 and ethanol extraction in our process depending on the final products we intend to make with our hemp oil extract.
We utilize Ethanol extraction for many of our products because it does a better job of preserving cannabinoids & terpenes due to the lower temperatures used. It’s also been extensively researched by the scientific community and regarded as one of the safest and preferred methods for herbal extraction, including pharmaceutical medications. Our process uses an organic food grade ethanol which is classified as Generally Regarded as Safe (GRAS) by the FDA as an extraction solvent. It’s a class 3 solvent which means that it is not known to be hazardous for humans.
We also use CO2 extraction for some of the extracts we use in our products because it preserves some of the beneficial plant material that ethanol removes. CO2 extraction is a non-toxic process that is clean and environmentally friendly because we use recycled CO2.
One part that many of our competitors touting CO2 extraction won’t tell you is that CO2 extraction yields a crude oil that still needs to be refined before it can be used in final products. This usually means winterization (freezing in ethanol) to separate out the fats & waxes from the oil. Unlike our competitors which just look for a marketing gimmick to sell product (or just don’t understand their own process), we want you to truly understand our process.
Before getting to a final product we have an evaporation process that removes all of the Ethanol used in either the extraction or winterization and a proprietary distillation process that further refines our hemp oil extract to the premium concentrate used in all of our products.
To cap it all off we get all of our concentrates and batch of products tested by an independent third party lab and make those available to you so you know what you’re getting.
