Ethanol or ethyl alcohol is commonly used as a solvent during the process of extracting cannabis to create concentrated oil. Ethanol is produced by the fermentation processes of sugars and yeasts.
Ethanol is considered to be as safe to handle as CO2 and as effective as butane in extracting cannabis. Since the FDA has classified ethanol as safe for human consumption, it is often used as a food preservative and additive. And as a result, ethanol extracted cannabis concentrates are used in edibles.
