xanthan gum is the thickening, suspension, emulsion stability, biological glue in one. the most superior performance. molecular side chain end containing xanthan gum acetonethe number of acid groups, has great influence on its performance. the general properties of xanthan gum with long chain polymer, but it contains more than the general functional polymer, show unique properties in specific conditions. its conformation in aqueous solution is diverse, not to show different characteristics to the conditions.
