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.
CMC Sodium (Carboxymethyl Cellulose Sodium)
CMC Sodium, or Carboxymethyl Cellulose Sodium, is a water-soluble anionic cellulose ether derived from natural cellulose. It appears as a white to off-white, odorless, tasteless powder or granule. Known for its excellent thickening, stabilizing, emulsifying, and water-retention properties, CMC is widely used in food, pharmaceutical, personal care, industrial, and detergent applications. It functions by modifying the rheological properties of solutions and suspensions, offering control over viscosity and flow. Its biocompatibility, non-toxicity, and biodegradability make it suitable for both human use and environmentally friendly formulations.
