1. Product Brief
Food‑grade CMC‑Na (Cellulose Gum) is high‑purity anionic water‑soluble cellulose ether, refined from natural cotton/wood pulp cellulose via alkalization, etherification and full purification. It is white‑off‑white fine powder, odourless, hygroscopic. Approved food additive, functions as thickener, stabilizer, water‑retention agent, suspending agent and film‑former. Multiple viscosity grades available for beverage, dairy, ice‑cream, bakery, sauce and instant food applications.
