Description
Cellulose Powder is a finely milled, purified form of cellulose obtained primarily from natural plant fibers such as wood pulp or cotton linters. As the most abundant natural polymer on Earth, cellulose consists of long linear chains of β-(1→4)-linked D-glucose units that form highly ordered crystalline and amorphous regions. Owing to its exceptional chemical stability, biodegradability, insolubility in water, and renewable origin, Cellulose Powder has become an indispensable ingredient in the pharmaceutical, food, cosmetic, paper, plastics, construction, and chemical industries.
Cellulose Powder is widely employed as a filler, anti-caking agent, bulking agent, binder, stabilizer, rheology modifier, absorbent, and reinforcing material. In pharmaceutical formulations, it improves tablet hardness and disintegration characteristics. In food products, it functions as a dietary fiber and texture enhancer. Cosmetic formulations utilize Cellulose Powder to improve sensory properties, absorb excess oil, and provide soft-focus effects. In industrial applications, it contributes to reinforcement, dimensional stability, and improved mechanical performance.
Its renewable nature, excellent compatibility with numerous formulation systems, and environmentally friendly profile have made Cellulose Powder one of the most important sustainable industrial raw materials.

Physical Properties
Cellulose Powder is supplied as a white to off-white, odorless, free-flowing powder composed of microscopic cellulose particles. Depending on particle size and manufacturing process, it may exhibit varying bulk density, flowability, and absorption capacity.
Typical characteristics include:
Its fibrous structure provides excellent absorption capacity while maintaining dimensional stability.
Chemical Properties
Cellulose is a natural polysaccharide composed exclusively of glucose units connected by β-1,4-glycosidic bonds. Extensive intermolecular hydrogen bonding gives the polymer remarkable mechanical strength and chemical resistance.
Important chemical characteristics include:
Although resistant to most common chemicals, cellulose can be hydrolyzed by strong mineral acids or specific cellulase enzymes.
Manufacturing Process
Commercial Cellulose Powder is produced through purification and mechanical processing of cellulose-rich plant materials.
Typical manufacturing stages include:
Specialized grades may undergo additional refinement to produce pharmaceutical or food-grade materials.
