α-Cellulose is widely used in the production of microcrystalline cellulose, a key excipient in pharmaceuticals, where it acts as a binder, disintegrant, and filler in tablet formulations. It is also employed in the food industry as a dietary fiber additive, enhancing texture and stability in products like baked goods and dairy. In the paper and textile industries, α-cellulose serves as a raw material for producing high-quality paper, fibers, and films. Additionally, it is utilized in the manufacture of cellulose derivatives such as cellulose ethers and esters, which find applications in coatings, adhesives, and construction materials. Its biocompatibility and biodegradability make it a sustainable choice in various industrial and consumer applications.
