Silicified Microcrystalline Cellulose – USPSolution for Optimum CompatibilitySilicification of MCC increased physical properties such as true density, Hausner ratio, porosity, ejection force and specific surface area. Other properties such as bulk and tap densities were reduced due to the amorphous and light character of fumed silica.MICCEL S is the mixture of microcrystalline cellulose and colloidal silicon dioxide (MCC/CSD at 98:2 ratio) and most compactible grade of SMC with flow characteristics similar to doubling the parties size of MCC.
