Pharmaceutical excipientsMicrocrystalline cellulose is a pure cellulose depolymerization product, prepared from natural cellulose. It is a white or off-white powder, odorless, tasteless, insoluble in water, ethanol, or toluene. It is compressible and has certain flowability and disintegrating properties. It is a common ingredient in low-fat ice cream and other frozen desserts.

Pharmaceutical excipientsMicrocrystalline cellulose (MCC) is a crystalline cellulose with a lower degree of polymerization obtained by partial hydrolysis of cellulose. It has good compressibility and strong binding force. The tablets pressed have high hardness and can be used as a "dry binder" for direct compression of powders. The foreign product is commercially known as Avicel, and there are several specifications according to different particle sizes.

Pharmaceutical excipientsMicrocrystalline cellulose is used in the pharmaceutical industry as an excipient and disintegrant for drugs. It is usually used as a diluent and has lubricating and disintegrating effects. It is relatively non-toxic and non-irritating, not absorbed orally, and does not have potential toxicity.

In addition to its use in the pharmaceutical industry, microcrystalline cellulose is also an important food base material in the food industry, known as dietary fiber. It is also used in the coatings industry or in cosmetic products. However, excessive use of microcrystalline cellulose can cause mild diarrhea. The most common use is as an excipient in drug formulations. If cellulose preparations are misused, inhalation or injection can cause cellulose swelling.

Pharmaceutical excipientsWith its unique structure and properties, microcrystalline cellulose is widely used in medicine and health, food and beverages, light chemicals and other sectors of the national economy as a disintegrant, stable emulsifier, etc. Because cellulose is widely found in nature, hundreds of billions of tons of biomass residues rich in cellulose are produced worldwide every year. If these residues are well converted and utilized, they will be a rich resource.
