Cellulose Ether
 Cellulose ether refers to a group of chemically modified cellulose derivatives where hydroxyl groups on the cellulose backbone are substituted with ether groups such as methyl, hydroxyethyl, or carboxymethyl groups. These modifications improve solubility, viscosity, and film-forming properties while maintaining biodegradability and non-toxicity. Cellulose ethers are white to off-white powders or granules that dissolve in water to form viscous, stable solutions. They are widely used as thickeners, binders, stabilizers, and film formers in industries such as construction, pharmaceuticals, cosmetics, food, and paper.
