Guar Gum (CAS No.: 9000-30-0, E412) is a natural non-ionic galactomannan polysaccharide extracted from the endosperm of guar bean (Cyamopsis tetragonoloba). Featuring outstanding thickening, stabilizing, water-retention and suspending performance, it delivers high viscosity even at low dosage. Thanks to its versatile functional properties, guar gum is widely adopted across multiple industrial sectors. Its main application areas are listed as below:
1. Food and Beverage Industry
This is one of the core application fields for guar gum, complying with GB 2760-2024, FCC and EU food-contact regulations.
Frozen & Dairy Products: Guar gum acts as stabilizer and ice-crystal inhibitor in ice-cream, frozen desserts and light cream. It restrains ice crystal growth and improves freeze-thaw stability; the maximum permitted dosage for light cream is 1.0 g/kg.
Sauces & Seasonings: Applied in salad dressings, mayonnaise and various sauces to enhance viscosity, stabilize oil-water phase separation and improve mouthfeel.
Bakery & Cereal Products: Used in baked goods, noodles and instant noodles for moisture retention, texture improvement, anti-adhesion and toughness enhancement.
Beverages: Functions as suspending agent and texture modifier in plant-based drinks, fruit-particle beverages and solid beverages, preventing solid sedimentation. Except for special regulated food categories, guar gum can be used according to production-process requirements in most food categories.
2. Personal Care & Daily Chemical Industry
In personal-care formulations: It serves as thickener, stabilizer and viscosity regulator in shampoos, body lotions and skin-care emulsions. In toothpaste formulas, it works as thickening and binding agent to optimize paste extrusion performance.
3. Textile Printing and Dyeing Industry
For textile production, guar gum is mainly used as: Printing paste thickener for reactive and disperse dye printing; it offers good permeability and clean wash-off property, improving pattern sharpness and reducing fabric damage. Sizing agent for yarn sizing to boost yarn strength and wear resistance.
4. Pharmaceutical & Nutraceutical Industry
Pharmaceutical-grade guar gum is applied in pharmaceutical preparations as: Tablet binder and disintegrant for solid oral dosage forms. Matrix material for sustained-release drug delivery systems to adjust drug release rate. Soluble dietary-fiber raw material in health-care supplements for nutritional-function formulations.
5. Paper Industry
Guar gum is utilized as retention-aid, filter-aid and surface-sizing agent in papermaking processes. It improves filler and fine-fiber retention, enhances paper surface smoothness, folding strength and printability, and is widely used for cultural paper and special-grade paper production.
6. Oilfield and Mineral Processing Industry
Guar gum plays a critical role in energy and mineral-processing sectors:
Oil & Gas Exploitation: Used as viscosifier, fluid-loss control agent and sand-carrying additive for hydraulic fracturing fluids. It increases fracturing-fluid viscosity and guarantees proppant transportation efficiency for oil-gas well stimulation. For high-temperature downhole conditions, modified hydroxypropyl guar derivatives are preferred over native guar gum.
Mineral Processing: Works as flocculant, filtration auxiliary agent in mineral separation, accelerating solid-liquid separation efficiency for ore-processing workflows.
7. Building Materials & Other Industrial Applications
Construction Materials: Serves as water-retention and thickening additive for gypsum products, cement-based mortar and coating systems, improving construction workability.
Feed Industry: Pellet binder in animal feed to strengthen pellet hardness and reduce powder loss.
Wastewater Treatment: Applied as auxiliary flocculant for solid-liquid separation in industrial wastewater treatment workflows.
