Microcrystalline cellulose (MCC) is a free-flowing crystalline powder (a non-fibrous microparticle). It is insoluble in water, dilute acids and most organic solvents, but slightly soluble in the alkali solution of 20%. It has a wide range of uses in the pharmaceutical excipients and can be directly used for tabletting of dry powder. It is widely used as pharmaceutical excipients, flow aids, fillers, disintegrating agents, anti-sticking agents, adsorbents, and capsule diluents.
Microcrystalline cellulose is a pure product of cellulose depolymerization, an odorless and tasteless crystalline powder prepared from the natural cellulose. In the pharmaceutical industry, the MCC products can be used as pharmaceutical excipients and disintegrating agents of tablets; in the food industry, MCC can be used as an important base material in functional foods and is an ideal health food additive; in the paint industry, MCC can be used as thickeners and emulsifiers of water-based coatings by using its thixotropic and thickening properties; in cosmetics, MCC has a combination of filler, thickening and emulsifying effects in itself, and has very good emulsifying capacity for the the oily substance. Thus it can be seen that MCC has a wide range of uses, and that the domestic demand for the product will continue to increase.
Microcrystalline cellulose, MCC for short, is a granular powder product with a size of about 10m, obtained from the hydrolysis of the natural cellulose in an acidic medium, making the molecular weight reduced to a certain range. It is mainly used in the pharmaceutical industry as a pharmaceutical excipient, and compared with the starch or starch derivatives has the following advantages.
