Xanthan gum

Product Overview

Xanthan gum (INCI: Xanthan Gum, CAS 11138-66-2) is a microbial, high-molecular-weight polysaccharide produced by fermentation of carbohydrate with Xanthomonas campestris. It forms translucent, shear-thinning (pseudoplastic) gels in water that are stable across a wide pH (1.5–13), temperature and salt range — making it ideal for food formulations, cosmetics, topical pharmaceuticals, and industrial fluids.

Xanthan Gum is a gum obtained by microbial fermentation from the xanthomonas campestris organism. it is very stable to viscosity change over varying temperatures, ph, and salt concentrations. it is also very pseudoplastic which results in a decrease in viscosity with increasing shear. it reacts synergistically with guar gum and tara gum to provide an increase in viscosity and with carob gum to provide an increase in viscosity or gel formation. it is used in salad dressings, sauces, desserts, baked goods, and beverages at 0.05–0.50%.

Typical Applications

Food & beverage: dressings, sauces, beverages, bakery and dairy analogues — texture & suspension (use at 0.05–0.5%).
Cosmetics & personal care: shampoos, creams, gels and lotions — stabilizer and rheology modifier.
Pharmaceuticals: suspending agent, binder, controlled-release matrices, ocular and topical formulations.
Oil & gas / Drilling fluids: viscosifier and suspension aid for drilling and completion fluids.
Industrial & adhesives: paints, inks, adhesives and ceramic slurries.

In foods, pharmaceuticals, and cosmetics as stabilizer and thickening agent. For rheology control in water-based systems. In oil and gas drilling and completion fluids.

Xanthan gum (corn starch gum) serves as a texturizer, carrier agent, and gelling agent in cosmetic preparations. It also stabilizes and thickens formulations. This gum is produced through a fermentation of carbohydrate and Xanthomonas campestris.

Grades, Packing & Supply Options

Grades available: food-grade (E-415), pharma grade, high-viscosity & specialty grades (high-salt tolerance), non-GMO and organic-certified grades on request.
Forms & packing: 25 kg bags, jumbo bulk bags (500–1000 kg), liquid dispersions (IBC), custom bulk FCL shipments.
Typical supply docs: COA, MSDS and technical datasheet provided with shipments; free sample policy (customer covers courier).

Performance & Formulation Tips

Mix xanthan into water using high-shear or pre-wet with glycerin/solvent for instant dispersion; synergizes strongly with guar and tara (galactomannane) to increase viscosity or form gels.
Typical use levels: 0.05–0.5% in foods; 0.1–1.0% in cosmetics; tailored higher concentrations for drilling fluids.

Safety & Regulatory Notes

Generally regarded as safe (GRAS in many jurisdictions) and well tolerated at recommended use levels; WHO ADI supports typical food use. Heat decomposition can produce irritating fumes — avoid overheating. Refer to product MSDS for handling, storage and exposure limits.
