Microcrystalline Cellulose Powder (MCCP) is a purified, partially depolymerized cellulose widely used as a pharmaceutical excipient in solid oral dosage forms. It is odorless, tasteless, non-toxic, and insoluble in water, providing excellent binding, diluent, and flow-enhancing properties. MCCP improves compressibility, tablet hardness, content uniformity, and processing efficiency, making it suitable for direct compression, granulation, and capsule filling applications.
