ARBOCEL®, powdered cellulose, is a plant-based functional filler. Powdered cellulose is chemically inert and is, thus, not metabolized by the human body. Because it is not digested, it has no functional caloric value. It is commonly used by formulators as an alternative to lactose when designing medicine for lactose-intolerant patients. ARBOCEL®’s binding properties and natural fiber structure lead to stable tablets with low friability.
