Glycerin is obtained from vegetable and animal oils and fats, or by the fermentation of glucose. It is used in the manufacture of chemicals, in food products, and in cosmetics. It is often necessary to remove color, odor constituents, and other contaminants.

Activated carbon is used in granular and powdered forms for the removal of trace color and odor in the final stages (“bleaching”) of purification. Activated carbon can also be used in the primary stage of crude glycerine purification to reduce bulk color and fatty acids.

Granular activated carbon

When purifying glycerin with activated carbon both color and odor are removed.
