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. ARBOCEL®'s binding properties and natural fiber structure lead to stable tablets with low friability.
Various grades of ARBOCEL® are available. The course granular grade, ARBOCEL® A 300 provides excellent flow and the fine, fibrous grades, M 80 and P 290, offer improved binding properties. All grades exhibit low moisture absorption, assuring good shelf life stability.
