GUM XANTHAN

Bulk Xanthan Gum for Cosmetic Formulation

Xanthan gum is a natural polysaccharide widely used in cosmetics as a thickener and stabilizer for creams, gels and emulsions. This guide covers what it is, how it is produced and its main applications in professional formulation, aimed at cosmetic laboratories, artisan soap makers and formulators sourcing raw materials in bulk.

What is Xanthan Gum?

Xanthan gum is a naturally derived polysaccharide obtained through fermentation of sugars by the bacterium Xanthomonas campestris. Its structure is mainly composed of glucose, mannose and glucuronic acid, giving it a strong ability to form viscous gels even at low concentrations.

For cosmetic use it is typically supplied as a fine powder, soluble in both cold and hot water, with good stability across a range of pH and temperature conditions. These properties make it a key ingredient for controlling texture and stability in aqueous emulsions used in professional formulation.

Main Cosmetic Uses of Xanthan Gum

Thickener for water-based formulas. Xanthan gum adjusts the viscosity of gels, shampoos and lotions without significantly affecting clarity or skin feel, adding body at very low dosage.

Emulsion stabilizer. It helps prevent phase separation in creams and lotions, keeping oils and active ingredients evenly dispersed throughout the product's shelf life.

Suspension of particles and actives. Its pseudoplastic behavior helps keep pigments, exfoliating particles or minerals suspended in formulations such as masks or body scrubs.

Sensory and application improvement. It gives formulas a silky texture and easier spreadability on skin, and is highly valued in liquid artisan soap making and certified natural cosmetics.
