Delivering efficient and robust formulations

GRINDSTED® Xanthan Gum is a naturally fermented product of carbohydrates and is applied in various liquid, semi-solid and solid pharmaceutical dosage forms.

Application in pharmaceutical formulations

GRINDSTED® Xanthan Gum readily dissolves in water under ambient conditions without the need of special high-shear equipment. As one of the most robust and efficient excipients, it tolerates high salt content, high temperature and is stable in a wide pH range. Low use levels of GRINDSTED® Xanthan Gum are sufficient to provide desired viscosities and textures. At the same time, its pronounced shear-thinning behavior enables handling of even highly viscous solutions. 


Key Benefits

  • Suspending agent for solids and oil droplets
  • Effective emulsion and foam stabilization
  • Low use level required (0.05-1%)
  • High viscosity at low concentration with pronounced shear-thinning behavior
  • Anti-syneresis effect
  • Stable in both acidic and alkaline solutions (approximate pH window 2-12)
  • Resistant to high temperatures
  • Compatible with solutions containing high concentrations of various salts
