Specification:

Function:

Milky white to light yellowish brown powder. It dissolves in water at room temperature to form a translucent viscous liquid, and is insoluble in organic solvents such as ethanol, isopropanol and acetone. The xanthan gum aqueous solution has good viscosity and is quite stable in the range of -4 to 80°C. When the concentration of ethanol, isopropanol or acetone in water exceeds 50% to 60%, it will cause precipitation of xanthan gum. It has strong resistance to acid and alkali and bio-enzyme degradation. In the range of Ph value of 1.5 to 13, the viscosity of the xanthan gum aqueous solution is not affected by the Ph value. Xanthan gum is a natural high molecular compound, with an oral LD50 of rats>10g/kg, and no special regulations are required for ADI (FAO/WHO, 1994).

Application:

Used as food additive and also used in oil field drilling.
