Primary Role
Thickening / Rheology · Moisture Control
Solubility
soluble in cold water forming a viscous colloidal solution; insoluble in most organic solvents (typical)
Applications & Use Cases
  • Water-retention agent and rheology modifier in cement-based and gypsum-based dry-mix mortars, tile adhesives, and renders, where it extends open time and reduces sag.
  • Thickener and workability aid in cementitious self-leveling underlayments and machine-applied plasters, improving pumpability and preventing premature water loss to the substrate.
  • Protective colloid and viscosity builder in water-based architectural paints and exterior insulation finishing systems (EIFS) to control flow, spatter, and film build.
  • Binder and film former in joint compounds, skim coats, and grouts, where it improves adhesion and crack resistance during cure.
  • Thickening and stabilizing agent in personal-care and household formulations such as lotions, creams, and liquid cleaners that require a non-ionic cellulosic rheology modifier.
