AVICEL SMCC 90 is silicified microcrystalline cellulose, a co-processed excipient comprising microcrystalline cellulose and fumed silicon dioxide. AVICEL SMCC 90 is used as a tablet excipient in pharmaceutical and dietary supplement formulations. The integration of microcrystalline cellulose and fumed silicon dioxide at the particle level enhances AVICEL SMCC 90 functional performance such as improved flow and processing compared to a blend of the individual components. The physical and functional properties of AVICEL SMCC 90 such as uniform size distribution, powder flow, and compactibility make it well suited for direct compression tablet manufacturing. AVICEL SMCC 90 helps improve productivity by allowing tablet manufacture at higher rates on high-speed tablet presses. Its compatibility with a wide range of active pharmaceutical ingredients (APIs) and excipients makes it a versatile excipient of choice for many pharmaceutical tablet formulations.
