Guar Gum Powder
Natural galactomannan thickener used in food, textile printing, oil and gas and pharmaceuticals.
- Chemical name
- Guar gum
- CAS number
- 9000-30-0
- Also known as
- Guar, Guaran, E412
Product overview
Guar gum powder is a natural polysaccharide obtained from the endosperm of guar beans. It hydrates in cold water to build viscosity at low concentrations.
It is used as a thickener and stabilizer in food and beverages, as a thickener in textile print pastes, as a viscosifier in oil and gas drilling and fracturing fluids, and as a binder in pharmaceutical and paper applications. Viscosity and mesh size vary by grade.
Applications
Typical uses for this chemical. Suitability for a specific process, and grade requirements for food, pharmaceutical or potable-water use, should be confirmed with our team.
