10 Reasons Ethanol Extraction is "Better" than CO2 Extraction!?October 3, 2021
Ethanol extraction is a better method than CO2 extraction… right? Well, maybe not. The fact of the matter is that ethanol extraction is common in the hemp and botanical industry because it is a powerful and effective solvent. This may be great, but there are underlying issues that are disregarded by extractors and overlooked by consumers too. These issues range from operating costs, to unsafe products and much more.
Food grade ethanol has been used for decades as a proper solvent to extract things like vanilla, essential oils and other consumable products. However, the same cannot be said for the hemp and botanical extraction industry. Due to its high cost, denatured ethanol is often used instead of food grade ethanol by many extractors. This opens the door for chemical denaturant residuals left in a final product for consumption. Not to mention, even denatured ethanol is vastly more expensive than CO2 in long term production. So, is ethanol really the best extraction solvent?
Dr. Jon takes 10 common reasons why ethanol is “better” than CO2 and debunks them one by one. Dr. Jon covers it all from residual denaturants, long-term costs, scalability and why these 10 reasons are not as true as they seem.
