Gum xanthan is a high-molecular-weight polysaccharide produced by bacterial fermentation, widely used as a thickening, stabilizing, and gelling agent in food, pharmaceuticals, and cosmetics. It enhances texture in sauces, dressings, and dairy products while improving emulsion stability in beverages and personal care formulations. This white to yellowish powder is non-toxic, soluble in cold water, and resistant to pH and temperature changes. Catalogue details include CAS 11138-66-2, storage at ambient conditions, and a signal word of "Warning" for safety handling. Molekula supplies gum xanthan from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
