1.Product Property
Guar gum is a highly purified natural polysaccharide extracted from guar beans, a type of leguminous plant widely cultivated in the Indian subcontinent. Due to its unique molecular structure and natural properties, it has rapidly become a superior new type of environmentally friendly papermaking additive; at the same time, it is also widely used in the fields of food, petroleum, and medicine.

3. Application scope and Usage
Guar gum (E412) is widely used as a natural thickener, stabilizer, and binder in food (ice cream, sauces, bakery), pharmaceuticals (tablet binder), cosmetics (lotions), oil drilling (fracturing fluid), and textile/paper industries due to its high viscosity, water retention, and cost-effectiveness.
4.Package and Storage
Guar gum is typically packaged in 25kg multi-layer kraft paper bags or moisture-proof woven bags with inner polyethylene lining. It should be stored in a cool, dry, well-ventilated warehouse away from direct sunlight and moisture, maintaining temperature below 25°C and relative humidity below 65%. The product remains stable for 24 months when properly sealed and stored, protected from pests and strong odors.
