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.
