  Product Detail  

 

Xanthan gum is a microbial polysaccharide produced through fermentation of corn starch by Xanthomonas campestris. It is widely used as a thickening agent, stabilizing, and suspending agent due to its ability to maintain viscosity under varying temperatures, pH levels, and shear conditions. Its versatility across food, pharmaceuticals, personal care, oil & gas, and industrial applications makes it one of the most commercially important hydrocolloids globally.
