Activated carbon is used in the production of glycerin for foods, cosmetics and pharmaceuticals, purifying it from crude glycerin to refined.
Refined glycerin is a versatile chemical used in oleochemical products as a basic chemical building block. It is also used in cosmetics (as an emollient and humectant), pharmaceuticals (in expectorants and cough syrups), and food (as a solvent, preservative and lubricant).
The choice of carbon is extremely important for the production of glycerin. The carbon needs to be of consistently high purity with very low leachable metal ions in order to remove organic impurities such as color and odor causing chemicals, without degrading the glycerin in the process. Our powdered activated carbon (PAC) and granular activated carbon (GAC) products are specifically developed with this in mind.
