Specialty Celluloses Microcrystalline cellulose (Avicel, FMC Corporation) is prepared by acid hydrolysis of cellulose using 2 M hydrochloric acid at 105 °C for 15 min. The highly reactive amorphous regions selectively hydrolyze, releasing the crystallites, which are subsequently mechanically dispersed.

How does microcrystalline cellulose MCC is made?

The MCC can be synthesized by different processes such as reactive extrusion, enzyme mediated, steam explosion, and acid hydrolysis. It is commonly manufactured by spray-drying the neutralized aqueous slurry of hydrolyzed cellulose. The MCC is a valuable additive in pharmaceutical, food, cosmetic, and other industries.

What are the ingredients in microcrystalline?

Microcrystalline cellulose (C6H10O5)n is refined wood pulp. It is a white, free-flowing powder. Chemically, it is an inert substance, is not degraded during digestion and has no appreciable absorption. In large quantities it provides dietary bulk and may lead to a laxative effect.

What is microcrystalline cellulose derived from?

Microcrystalline cellulose (MCC) for industrial purposes is usually obtained from wood pulp and purified cotton linters. Each of these is a “natural” source, cotton is a high value-added crop and wood pulp generally originates in some manner from deforestation.
