Commercial Information
Storage & Shipping
Storage Conditions
Store in sealed original lined bags in a cool, dry, ventilated area. Protect from moisture and contamination and keep away from strong oxidizers and ignition sources.
Shelf life
At least two years under normal cool, dry storage in sealed original packaging.
Packaging
25 kg lined paper bags
Handling & Protection
Use controlled powder addition and local extraction to limit dust. Wear suitable gloves and eye protection; avoid inhalation and prevent powder accumulation near ignition sources. Clean spills promptly because hydrated gum can make floors slippery.
What Is Xanthan Gum?
Xanthan gum, CAS 11138-66-2, is a high-molecular-weight polysaccharide made by fermentation. It gives strongly shear-thinning solutions with high low-shear viscosity, which keeps cuttings and weighting materials suspended in water-based drilling fluids while the fluid stays pumpable.
The supply specification sets pH 5.5–8.0 for a 1% solution and viscosity ≥1,200 cP for 1% gum in 1% KCl. A 0.28% seawater test gives rheology readings at six speeds. Loss on drying is ≤13%, with 100% passing 28 mesh and at least 95% passing 42 mesh.
Add the powder gradually under shear to avoid lumps; hydration depends on water quality, salinity and other additives. This is an industrial and oilfield grade, not a food or pharmaceutical grade. It is not regulated as dangerous goods; store it dry and control dust.
As a xanthan gum supplier and exporter in China, ZXCHEM packs the beige powder in 25 kg lined paper bags.

Xanthan Gum Applications
Drilling-fluid viscosity
Viscosifier that suspends cuttings and barite in water-based muds. Low-shear rheology and compatibility with salts and solids are tested.
Brine and seawater fluids
Rheology modifier for completion, workover and seawater-based fluids. Performance is checked at the actual concentration and temperature.
Industrial thickening
Thickener and suspending agent for industrial formulations. Hydration and microbial stability are checked for the end use.

Xanthan Gum FAQ
Which Xanthan Gum grade should I choose?
The listed supply specification is Oilfield / industrial rheology grade. Check the TDS for assay and impurity limits, then test a sample for compatibility and performance in your process.
Can I request a Xanthan Gum sample for testing?
Yes. We can provide free samples for testing. Tell us the application, the grade you need and the tests you plan to run.
How is Xanthan Gum packed and shipped?
Standard packing is 25 kg lined paper bags. The usual MOQ is 1,000 kg, with a lead time of approximately 14 days from order confirmation. It ships as non-dangerous goods.
Which documents are available for Xanthan Gum?
The TDS lists the supply specification and the SDS covers safety and transport; both can be downloaded on this page. Each shipment comes with a batch COA.
