Introduction
Xanthan gum, an extracellular bacterial polysaccharide, is produced through fermentation by Xanthomonas campestris using succrose. Xanthan gum consists repeating units of five monosacchanides formed by two D-glucose, two D-mannose, and one D-glucuronic acid. The molecular weight of Xanthan gum is between 2× 106~2× 107. It possesses outstanding viscosity-enhancing property and solubility in water and is excellent stable to a large range of temperatures and pHs. The gum can be widely used in medicine and daily chemical field.
Properties
Comparing with other kinds of gum, xanthan gum has many advantages.
Outstanding viscosity-enhancing property and solubility in water.
Unique pseudo-plasticity rheological property of xanthan gum makes it high-efficient emulsifier and stabilizer.
Excellent stability to large range of temperature and pH change.
Stable compatibility with acid, alkaline, brine, enzyme, surface active agent, antiseptic, oxidant and other thickener.
Perfect synergistic action when compounding with guar gum, locust bean gum and other gums.
Usage
Medicine field: It can be used as liquid formulations and semi-solid dosage forms of suspending agents and thickeners to improve the taste of the drug, inhibition of drug layer; Can significantly increase the physical stability of preparations, when the coating is easy dumping and smear. Xanthan gum can reduce the gastrointestinal stimulation for its strong viscous, and improve the bioavailability of drugs. Xanthan gum with the antioxidant activity has protective effects on the easily oxidized substances. In addition, xanthan gum can be used as medical raw materials, with preparation of joint cavity injection, for the improvement and the treatment of osteoarthritis.
Daily chemical field: Using cosmetics, oral care products, detergents and lotions in life, Xanthan gum can improve the paste state, the dispersion and absorption of products. It is easy filling and extrusion, which can improve moisture retention and cosmetics membrane, to extend the cosmetic effect.
