Ethanol and activated carbon are two key materials in the CBD/hemp industry. Ethanol is a popular choice for hemp extraction, while activated carbon is used for purification and filtration. The chemical interaction between these two materials is important for the production of high-quality hemp extracts.

Ethanol precipitation is a simple, efficient process that allows for the purification of traditional medicine herbal formulas. This technology operates on the principal that most bioactive compounds are increasingly soluble in higher ethanol concentrations, while compounds that are irrelevant or unsafe are usually less soluble. Increasing the ethanol concentration allows for impurities to precipitate out of solution while bioactive compounds remain. The result is a potent, bioactive concentrate that can be used to make tablets or granules in place of the less convenient, traditional decoction.

Polysorbate 80 is a low molecular weight, nonionic, amphiphilic compound. It is commonly used as an emulsifier in foods to improve texture, consistency, and mouthfeel of food products. Food grade polysorbate 80 may be used in bakery products to improve density, as a solubilizer in water-oil mixtures, and as a texture-enhancer in chocolate and ice cream.
