Primary Role
Thickening / Rheology · Viscosity Modification
Applications & Use Cases
  • Drilling-mud additive in oil and gas operations, where it controls fluid loss (filtration) and modifies rheology to stabilize the wellbore and suspend cuttings.
  • Thickener, water binder, and rheology modifier in water-based coatings, paints, latex systems, and construction mortars/tile adhesives to improve workability and sag resistance.
  • Food-grade cellulose gum (E466) used as a thickener, stabilizer, and texturizer in beverages, dairy, sauces, and baked goods.
  • Binder and anti-redeposition agent in laundry detergents and HI&I cleaning formulations to keep soil suspended in the wash liquor.
  • Film former and viscosity builder in textile sizing/printing pastes, ceramics, and paper coatings.
