Xanthan Gum

Basic Information

Xanthan gum is a microbial exopolysaccharide with a wide range of functions produced by fermentation engineering with carbohydrates as the main raw material (such as corn starch). It has unique rheology, good water solubility, stability to heat and acid and alkali, and good compatibility with various salts. As a thickener, suspending agent, emulsifier, and stabilizer。

Xanthan gum can be widely used in more than 20 industries such as daily chemicals, food, petroleum, and medicine, it is the microbial polysaccharide with the largest production scale and extremely wide uses in the world.

1.Excellent suspension characteristics and rheology control

2.Superior viscosifier

3.Performs well in fresh water,seawater,brine and saturated salt environments

4.Optimizes borehole hydraulics

5.Temperature stable to 94℃(up to 138℃ with the addition of 3% salt and an oxygen scavenger)

NOTE: Care should be taken when adding with cationic and trivalent ions, such as

chromium, as precipitation may occur.


Due to its unique properties, xanthan gum is widely used in more than a dozen fields such as food, petroleum, medicine, and daily chemical industry.

  1. Food: Xanthan gum is added to many foods as stabilizer, emulsifier, suspending agent, thickener and processing aid. Xanthan gum can control the rheology, structure, flavor and appearance of the product, and its pseudoplasticity can ensure a good taste, so it is widely used in salad dressings, bread, dairy products, frozen foods, beverages, condiments, brewing, In confectionery, pastries, soups and canned foods.

  2. Daily chemical industry: Xanthan gum contains a large number of hydrophilic groups, which is a good surface active substance, and has the functions of anti-oxidation and preventing skin aging. Therefore, it is used in almost most high-end cosmetics. Contains xanthan gum as its main functional ingredient. In addition, xanthan gum can also be used as a component of toothpaste to thicken and shape, reducing tooth surface wear.

  3. Medical aspects: Xanthan gum is the functional component of the hottest microcapsule drug capsules in the world at present, and plays an important role in controlling the sustained release of drugs; due to its strong hydrophilicity and water retention, there are many Specific applications in medical operations, such as forming a dense water film to avoid skin infection; reducing thirst of patients after radiotherapy, etc.

  4. Application in industry and agriculture: In the petroleum industry, due to its strong pseudoplasticity, a low-concentration xanthan gum (0.5%) aqueous solution can maintain the viscosity of the drilling fluid and control its rheological properties. The viscosity of the part is extremely small, which saves power; while the relatively static drilling part maintains high viscosity, thereby preventing the well wall from collapsing. And because of its excellent salt resistance and heat resistance, it is widely used in drilling in special environments such as oceans and high-salt areas, and can be used as an oil recovery agent to reduce dead oil areas and increase oil recovery.
