Cellubrite MCC is a polysaccharide consisting of β(1→4) linked glucose units. MCC has no taste nor odour. It is non-toxic and contains almost exclusively dietary fibre. Cellubrite MCC is readily biodegradable. The crystalline powder is hygroscopic, but insoluble in water; with water it swells to form a gel.
Cellubrite MCC comes in various custom made sizes that have different properties. The main applications is as tablet disintegrating agent in pharmacy, food and detergents. In other markets it acts as emulsifier, dispersing agent stabilizer, anti-caking agent. Because of its properties, among which chemical purity and high crystallinity, many more applications start to develop like in sprays, oral suspensions and lotions. Here, it is an alternative to synthetic gels or indegradable polymers.
Cellubrite MCC is made from fibrous plant and wood pulp. After treatment of alpha-cellulose with mineral acid and HCl, the amorphous cellulose parts are removed, leaving the crystalline cellulose parts for the purification step.
