α-Cellulose is widely used in the production of microcrystalline cellulose, a key excipient in pharmaceuticals for tablet binding and disintegration. It serves as a dietary fiber supplement in food products, promoting digestive health. In the paper industry, it enhances paper strength and durability. Additionally, it is utilized in the manufacture of cellulose derivatives like cellulose ethers, which are essential in construction materials, personal care products, and coatings. Its high purity makes it suitable for use in chromatography as a stationary phase. α-Cellulose also finds applications in biodegradable plastics and composites, contributing to sustainable material development.
