Xanthan Gum CAS 11138-66-2

Xanthan Gum is an anionic polysaccharide widely used as a high-efficiency thickener, stabilizer and rheology modifier in food, cosmetics, oilfield and many industrial formulations. It offers excellent pseudoplastic (shear-thinning) behavior, high thermal stability and stable performance over a wide pH and salt range, making it ideal for demanding process conditions.

Physicochemical Properties

Product Introduction

Xanthan Gum is produced by the controlled fermentation of carbohydrates using Xanthomonas campestris, followed by purification, drying and milling. The resulting polymer forms highly viscous, stable solutions at low dosage levels (typically 0.1–0.5%), and exhibits strong suspension and anti-settling performance.

Thanks to its unique rheology, Xanthan Gum delivers:

• Instant thickening even at low concentration
• Excellent suspension of solids, pulp and particulates
• Stable viscosity over a wide range of temperature, pH and salt levels
• Improved texture and mouthfeel in food applications
• Enhanced carrying capacity and cuttings transport in oilfield drilling fluids

Our factory can supply food grade Xanthan Gum compliant with major food regulations, as well as industrial and oilfield grades with tailored particle size, viscosity and dispersibility to fit different processing needs. Full supporting documents such as COA, TDS and MSDS can be provided with each shipment.

Applications

1. Food & Beverage

• Thickener and stabilizer in sauces, dressings, ketchup and gravies
• Suspension and mouthfeel enhancer in juice drinks and flavored beverages
• Texture improver in dairy products, ice cream and plant-based drinks
• Structure builder and moisture retention agent in bakery and gluten-free products
• Synergistic thickening with other hydrocolloids (e.g., guar gum, locust bean gum)

Benefits for food manufacturers:

• Stable viscosity during processing (heating, cooling, freezing–thawing)
• Enhanced product consistency and consumer perception of quality
• Reduced phase separation and sedimentation during storage

2. Oilfield & Mining

• Rheology regulator and viscosifier in water-based drilling fluids
• Suspension and carrying agent for cuttings and weighting materials
• Fluid loss control and hole cleaning in complex formations

Benefits for oilfield service companies:

• Strong viscosity at low dosage, helping to optimize overall mud cost
• Excellent stability in saline and high-electrolyte environments
• Compatible with many common additives in drilling and completion fluids

3. Cosmetics & Personal Care

• Thickener and stabilizer in creams, lotions, gels and toothpaste
• Suspension of pigments and actives in skincare and makeup formulations
• Provides smooth, non-sticky skin feel and good spreadability

4. Other Industrial Uses

• Stabilizer in agricultural formulations (fertilizers, pesticide suspensions)
• Rheology modifier in coatings, inks and construction chemicals
• Binder and thickener in various specialty chemical systems

We can recommend suitable grades based on your end application and processing conditions.

Storage Conditions

To maintain quality over the full shelf life, Xanthan Gum should be stored under the following conditions:

• Keep in cool, dry and well-ventilated warehouse
• Recommended storage temperature: ≤ 25 °C
• Relative humidity: < 50% where possible
• Keep bags tightly closed after opening to avoid moisture uptake
• Store away from strong odors and volatile chemicals to prevent odor absorption
• Avoid direct sunlight, high heat and sources of ignition

Under correct storage conditions in its original unopened packaging, the typical shelf life is 24 months from production date. After long storage, a quality check (viscosity, moisture) is recommended before use in critical applications.

Safety Precautions

Xanthan Gum is generally recognized as safe (GRAS) for food use and is considered of low toxicity. However, as with all fine powders, appropriate handling practices are important:

• Avoid generating excessive dust during transfer, mixing or packaging
• Use local exhaust ventilation or dust collection where possible
• Wear suitable dust masks/respirators, safety glasses and protective gloves when handling large quantities
• In case of eye contact, rinse immediately with plenty of clean water
• If inhaled as dust and irritation occurs, move to fresh air and seek medical advice if symptoms persist
• Spilled material can create slippery surfaces; sweep or vacuum up carefully and dispose of in accordance with local regulations
• Keep out of reach of children and non-trained personnel
