Xanthan gum is a water-soluble polysaccharide, commercially produced by a distinct fermentation process of Xanthomonas campestris, and does not contain any other polysaccharide, such as starch, guar gum or other naturally occurring polymers or their derivatives. Xanthan gum is an off-white, free flowing granular powder.
Xanthan gum is a premium quality biopolymer powder designed to provide maximum solids suspension and hole cleaning in vertical and highly deviated wells as well as horizontal directional drilling applications. Xanthan gum is a distinctive product and able to produce a thixotropic shear thinning fluid.

- Viscosify fresh water and brine-based fluids used for drilling, milling, underreaming, and gravel packing operations.
- Suspend bridging agents and weighting materials in fresh water and brine systems.
- Helps disperses easily in fresh water mud, and brines
- Provides thixotropic properties and non-Newtonian flow characteristics over a wide salinity range at low concentrations
- Provides excellent suspension without the need for clays
- Minimizes the potential for formation damage
The dissolution of the product depends on the medium and the process: it is improved by heat-treatment (time, temperature), shear-stress (propeller, exchanger, homogenizer). A complete dissolution can be obtained in cold conditions.
Packaging & StorageXanthan gum is packaged in 50lb or 55lb plastic lined 4-layer paper bags and shipped via an approved common carrier. DOT classification – Non Hazardous.
Shelf LifeAPI xanthan gum has a shelf life of 24 months from date of manufacture when stored in a clean dry area
