Xanthan Gum CAS 11138-66-2
Sinochem is a major global Xanthan Gum supplier. Backed by a team of chemical industry experts, we are dedicated to supporting your business with top-tier, reliable supply chains for China Xanthan Gum.
Xanthan gum is a high-molecular-weight polysaccharide produced by the fermentation of carbohydrates by the bacterium Xanthomonas campestris. It is highly soluble in both cold and hot water but remains insoluble in organic solvents. Acting as a superior thickener, stabilizer, and rheology control agent, it finds extensive applications across the food, pharmaceutical, cosmetic, and oil drilling industries.
- Exceptional Rheological Control: Provides high pseudoplasticity for stable suspension of solids and emulsions.
- High Viscosity at Low Concentration: Achieves significant viscosity and gelling effects with very low usage levels, making it highly cost-effective.
- Outstanding Temperature & pH Stability: Xanthan Gum maintains its viscosity and stability across a wide temperature range and broad pH scales (from highly acidic to highly alkaline), showing remarkable resistance to enzymatic degradation, acids, and alkalis.
- Powerful Synergistic Interactions: When combined with other hydrocolloids (such as Locust Bean Gum or Guar Gum), it exhibits powerful synergistic viscosity enhancement, unlocking a broader range of texture modifications and superior emulsion stabilization effects.

Xanthan Applications
- Food Industry (E415): Widely added to many foods as a premier stabilizer, emulsifier, suspending agent, thickener, and processing aid. It optimizes texture, moisture retention, and mouthfeel in salad dressings, sauces, bakery products, and dairy alternatives.
- Oil Drilling & Industrial Chemicals: Due to its high commercialization and unmatched performance among microbial polysaccharides, it is extensively used in oil drilling muds. It functions as an outstanding rheology control agent, enhancing cuttings transport and reducing fluid loss in high-temperature, high-salt oil field environments.
- Cosmetics & Personal Care: Xanthan gum molecules contain numerous hydrophilic groups, making it a potent surfactant with antioxidant and anti-aging properties. It is widely used in high-end cosmetics, lotions, and toothpastes to provide ideal thickening, stabilize emulsion formulations, and reduce tooth surface abrasion.
- Pharmaceuticals & Medicine: It plays a crucial role in microencapsulated drug capsules for controlled drug release. Due to its strong hydrophilicity and water-retention properties, it forms a dense water film, making it highly effective in specific medical procedures such as preventing skin infections or alleviating thirst in patients after radiotherapy.
Frequently Asked Questions (FAQ)
Q: What is the main difference between Food Grade and Industrial Grade Xanthan Gum?
A: The main difference lies in the level of purification, regulatory compliance, and testing standards. Food Grade Xanthan Gum (E415) strictly adheres to global food safety regulations (like FDA, FCCIV, and EFSA), ensuring ultra-low heavy metal content, strict microbiological control, and no residual chemical purification solvents. Industrial Grade Xanthan Gum focuses purely on performance indicators like high shear-thinning, salt tolerance, and viscosity under extreme stress, making it perfect for oil drilling muds and agricultural coatings where human ingestion is not a factor.
Q: What are the commercial formulation benefits of combining Xanthan Gum with Guar Gum?
A: Combining Xanthan Gum with Guar Gum unlocks a powerful intermolecular synergistic effect known as hydrocolloid synergism. When mixed in specific ratios, the total blend viscosity is significantly higher than the sum of the two gums used individually. This allows chemical formulators and food chemical engineers to drastically reduce the total gum dosage while achieving the exact same thickening and stabilizing targets, resulting in significant savings on raw material procurement costs.
