Xanthan Gum is a high-molecular-weight polysaccharide with the general repeating-unit formula (C₃₅H₄₉O₂₉)ₙ. It is commonly supplied as a white to cream-coloured fine powder and readily disperses in water to form viscous solutions. Xanthan Gum is an anionic heteropolysaccharide containing glucose, mannose, and glucuronic acid units, with a cellulose-like backbone and trisaccharide side chains.

Xanthan Gum is valued for its excellent thickening, stabilising, and rheological properties. Common laboratory applications include viscosity modification, preparation of aqueous formulations, suspension stabilisation, emulsion research, microbiological studies, and biochemical experiments. It is also used in research involving polymer behaviour, hydrocolloids, and the physical properties of aqueous solutions.

Its ability to produce highly viscous solutions at relatively low concentrations, together with its stability across a broad range of pH values and temperatures, makes Xanthan Gum useful in biotechnology, pharmaceutical research, food science, analytical chemistry, and general laboratory applications. It may also be used in specialised formulations, cosmetic research, and industrial processes requiring a water-soluble thickening and stabilising agent. The appropriate grade, viscosity, and purity should be selected according to the requirements of the intended application.

KSFE Malaysia supplies laboratory chemicals and scientific products for research institutions, educational facilities, and general laboratory applications.

Safety Note: Xanthan Gum is generally considered a low-hazard material when handled appropriately. However, airborne powder may cause respiratory irritation, while direct contact with the eyes may cause mechanical irritation. Fine powder may also create slippery surfaces when spilled and can present a dust hazard under certain conditions. Avoid inhalation of dust and use appropriate personal protective equipment, including laboratory gloves, safety goggles, and a suitable dust mask when necessary. Store in a tightly closed container in a cool, dry place away from moisture. Follow the supplier's safety data sheet (SDS) for proper handling, storage, and disposal.
