KELZAN® Xanthan Gum

The KELZAN® line of industrial xanthan gum products can be used to modify the texture of industrial products and to stabilize suspensions, oil-in-water emulsions and foams against separation.

KELZAN industrial grade xanthan gum is a high molecular weight, anionic polysaccharide produced in a pure culture fermentation process. KELZAN xanthan gum functions as a hydrophilic colloid to thicken, suspend and stabilize water-based systems.

KELZAN xanthan gums are highly pseudoplastic, or shear thinning. At rest, solutions are viscous; however, when mixed, pumped, sprayed or poured, the solution is thin. Once the force is removed, the solution regains its initial viscosity almost immediately. KELZAN products have outstanding stability with respect to pH, salt, or heat, and excellent compatibility with other ingredients. All are readily soluble in both hot and cold water systems. The pseudoplastic rheology of KELZAN is especially useful in systems involving suspensions.

Formulators can choose from a family of KELZAN products designed to meet specific needs and processing conditions.

Benefits of KELZAN Xanthan Gum

  • High viscosity at low concentrations
  • Extreme pseudoplasticity (high viscosity under low shear, but low viscosity under high shear)
  • Very good long-term temperature stability
  • Shear stability
  • Very good long-term pH stability
  • Efficiency in suspension (use level generally below 0.5% – often below 0.3%)
  • Compatibility with high salt concentrations
