VANZAN^® D

VANZAN^® D Xanthan Gum is a surface-treated grade of xanthan gum that provides easy dispersion with rapid viscosity development, without the formation of lumps or "fish eyes". VANZAN D is surface-treated to make it temporarily insoluble. This facilitates dispersion and prevents the gum from dissolving until the surface treatment is removed by raising the pH of the system to 9 or greater. It is particularly convenient for systems where the final pH is alkaline.

The rheology of VANZAN D solutions is remarkably stable over a broad temperature range and will not change significantly between ambient temperature and 60°C. Additionally, VANZAN D has excellent freeze/thaw stability. Mixtures of xanthan gum with water-swellable clays or certain galactomannans produce synergistic rheological effects. The mixtures will provide greater thickening, stabilizing and suspending properties than those developed by the individual components of the mixture.

Typical Use Levels: Between 0.1% and 1%
