Cellulose-derived refers to materials produced by modifying or processing cellulose, the biopolymer that forms plant cell walls. This category includes cellulose derivatives—chemically modified forms such as esters and ethers—and nanoscale cellulose materials derived from cellulose by mechanical, chemical, or enzymatic treatment. Cellulose-derived products are often biobased and can be designed to be biodegradable or recyclable.

Common cellulose derivatives include cellulose esters (for example cellulose acetate, cellulose triacetate) and cellulose ethers (such as methylcellulose, hydroxyethyl cellulose, carboxymethyl cellulose). Nanocellulose consists of cellulose nanocrystals and cellulose nanofibrils produced by acid hydrolysis or mechanical defibrillation of cellulose fibers; the surface can be tailored via chemical treatment.

Production involves chemical modification of cellulose or processing into nanoscale forms. Esterification and etherification introduce acetyl, methyl, hydroxypropyl, or carboxymethyl groups. Oxidation or periodate cleavage creates oxidized derivatives. Nanocellulose is obtained by mechanical disintegration, often aided by pretreatment or enzymatic steps; dissolution of cellulose for some routes requires specialized solvents.

Properties vary widely; derivatives can be soluble in water or common solvents, while nanocellulose exhibits high strength and stiffness and acts as a reinforcing filler. Applications span packaging films (cellulose acetate), thickening and stabilizing agents in food and cosmetics (CMC, methylcellulose), pharmaceuticals (excipients), and advanced composites and filtration membranes from nanocellulose.

Because cellulose-based materials are biobased, they are often considered more sustainable than petroleum-based polymers, though environmental impact depends on source material and processing energy. Safety profiles are generally favorable; many derivatives are approved for food, pharmaceutical, and cosmetic uses under regulatory frameworks such as E numbers (e.g., E466 for carboxymethyl cellulose).
