MCC 200 (MICROCRYSTALLINE CELLULOSE)

Microcrystalline Cellulose (MCC 200) is a highly purified, partially depolymerized cellulose derived from premium-grade wood pulp, serving as an indispensable excipient in the pharmaceutical, nutraceutical, and food industries. Characterized as a fine, white, free-flowing powder, MCC 200 is chemically inert, insoluble in water, organic solvents, and dilute acids, ensuring stability and compatibility within diverse formulations. The "200" designation typically refers to its particle size distribution, often around 75 microns (200 mesh), which imparts superior flow properties and excellent compressibility, making it a preferred choice for direct compression tableting. Its consistent particle morphology and high bulk density contribute significantly to content uniformity and efficient manufacturing processes, critical for producing high-quality finished products. This versatile ingredient is a cornerstone for formulators seeking reliability and performance.

While primarily utilized for its functional properties, Microcrystalline Cellulose, being a form of cellulose, inherently contributes to dietary fiber. As an insoluble fiber, it passes through the digestive tract largely unchanged, adding bulk to stool and supporting regular bowel movements. Research consistently highlights the importance of dietary fiber intake for maintaining gut motility and overall digestive health, with studies in the American Journal of Clinical Nutrition demonstrating a link between higher fiber consumption and reduced risk of chronic diseases. Although MCC is not typically consumed as a primary fiber supplement, its presence in significant quantities within certain formulations can contribute to the daily recommended fiber intake. Unlike many active compounds, MCC does not exert direct pharmacological effects; rather, its benefits are rooted in its physical and chemical stability, acting as a benign, physiologically inert component that aids in nutrient delivery and structural integrity.

MCC 200 finds widespread application as a diluent, binder, disintegrant, and anti-caking agent in tablet and capsule formulations, as well as a stabilizer in suspensions and emulsions. Its exceptional binding capabilities allow for the creation of robust tablets with optimal hardness and friability, even at high compression speeds, a feature extensively documented in pharmaceutical technology journals. Quality considerations for MCC 200 are paramount, focusing on stringent specifications for particle size, bulk density, moisture content, and microbial purity, adhering to pharmacopeial standards such as USP/NF, EP, and JP. The manufacturing process involves controlled acid hydrolysis of wood pulp, followed by purification and spray-drying, ensuring a product with consistent physicochemical attributes. This rigorous process is critical for ensuring lot-to-lot consistency, which is vital for reproducible product performance and regulatory compliance in finished goods.
