Chemical Structure
Basic Info
Guar Gum (CAS 9000-30-0), derived from the refined endosperm of the seeds of Cyamopsis tetragonoloba, is a high-molecular-weight non-ionic polysaccharide composed of galactomannan units. Renowned for its cold-water solubility and exceptional hydration rate, it serves as one of the most cost-effective natural rheology modifiers available in modern processing industries.
Owing to its high concentration of hydroxyl groups, Guar Gum exhibits pronounced hydrogen bonding capability when dispersed in aqueous solutions. It demonstrates strong pseudoplastic (shear-thinning) behavior, rapidly forming high-viscosity gels at low concentrations without requiring thermal activation. It acts as an essential thickening agent, emulsion stabilizer, water-binding controller, and texture modifier across food processing, pharmaceutical, cosmetic, and heavy industrial applications.

Product Packaging
To guarantee consistent hydration, purity, and rheological performance, every production lot of CAS 9000-30-0 undergoes multi-stage analytical testing in our specialized quality control laboratory.
Viscosity & Hydration Rate Profiling: Measured via Brookfield Viscometer in 1% aqueous solution at designated intervals (2 hours, 24 hours) at 25°C to confirm peak viscosity achievement.
Moisture Content & Loss on Drying: Maintained strictly below 12.0% via automated halogen moisture analyzers to eliminate microbial risks and preserve shelf stability.
Acid-Insoluble Matter & Ash Content Testing: Gravimetric evaluation ensures minimal seed coat residue and verifies pure endosperm content.
Microbiological Screening: Comprehensive testing for Total Plate Count (TPC), Yeast & Mold, E. coli, and Salmonella to guarantee strict hygiene standards for food and personal care grades.
Particle Size Distribution (Sieve Analysis): Verified using laser diffraction and analytical sieving to secure consistent dispersion and prevent clumping during customer processing.
Guar Gum’s versatility allows for broad integration across distinct market segments:
Food & Beverage Sector:
Dairy & Frozen Desserts: Inhibits ice crystal growth in ice cream, enhances creaminess, and prevents syneresis (water separation) in yogurt and soft cheese.
Bakery & Pastry: Increases dough yield, retains moisture for prolonged shelf life, and improves structural elasticity in gluten-free formulations.
Sauces, Dressings & Condiments: Serves as a cold-water soluble thickener providing stable suspension of particulate matter under acidic processing conditions.
Personal Care & Cosmetics:
Functions as a natural thickener and emulsion stabilizer in lotions, creams, and toothpaste formulations.
Pharmaceutical Formulations:
Acts as a binder and disintegrant in tablet formulations and as a viscosity builder in oral suspensions.
Industrial Applications (Oil Drilling, Mining & Paper):
Utilized as a fluid-loss control agent and friction reducer in oil well drilling muds, as well as a wet-end additive in paper manufacturing to improve sheet formation and tensile strength.
FAQ
A: To achieve rapid and smooth dispersion, it is recommended to dry-blend Guar Gum powder with other dry ingredients (such as sugar, salt, or starch) before introducing it into water. Alternatively, slurrying the powder in a non-solvent medium (e.g., vegetable oil or alcohol) prior to aqueous mixing ensures homogenous hydration under high-shear agitation.
A: Guar Gum demonstrates stable viscosity across a broad pH spectrum, typically between pH 4.0 and 10.0. In mildly acidic systems (pH 3.5–5.0), it maintains good functional stability. However, strong acids (pH < 3.0) combined with heat can hydrolyze the galactomannan backbone over time.
A: Materials should be kept sealed in their original moisture-barrier packaging (e.g., multi-wall paper bags with PE liners) in a cool, dry, and well-ventilated space below 25°C and under 60% relative humidity. Avoid direct contact with ground surfaces and moisture-laden air to prevent caking and loss of hydration efficiency.
