The KELZAN® Line of Industrial Xanthan Gum

CP Kelco offers a range of biopolymers to thicken, suspend and stabilize emulsions and other water-based systems. The KELZAN® xanthan gum line of industrial products can be used to modify the texture of industrial products and to stabilize household cleaners, fabric care products, 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 using the bacterium Xanthomonas campestris. The composition and structure of xanthan gum produced by commercial fermentation is identical to the nature-based occurring polysaccharide formed by Xanthomonas campestris on plants belonging to the cabbage family. Process control and rigorous quality standards throughout production guarantee consistent, reliable product performance.

KELZAN xanthan gums are highly pseudoplastic, or shear thinning. This pseudoplastic rheology is especially useful in systems involving suspensions. At rest, solutions are viscous; however, when mixed, pumped, sprayed, or poured, the solutions 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.

Formulators can choose from a family of KELZAN products designed to meet specific needs and processing conditions of formulations such as liquid detergents, toilet bowl cleaners, hard surface cleaners, oven cleaners, abrasive cleaners, polishes.

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
