Xanthan gum

Detailed introduction

1. Product Description

Xanthan gum, also known as xanthan gum, xanthan gum, xanthomonas polysaccharide, is white or light yellow powder, is the starch after fermentation of polysaccharide polymer after processing and refined. The main composition is a polysaccharide polymer compound composed of D-glucose, D-mannose and D-glucuronic acid according to 2:2:1, with a relative molecular mass of more than 1 million. It is a kind of white to light yellow powder after processing and refining the polysaccharide polymer produced by the fermentation of starch by the black rot disease xanthomonas. Because of its unique macromolecular special structure and colloidal properties, and commonly used as thickeners, stabilizers, adhesives, emulsifiers and suspending agents.

2. Product advantages

Stable supply: GMP conditions of production, fully domestic.

Meet the needs of different regulatory market standards: CP/USP/EP.

Higher safety: Xanthan gum is obtained by fermentation, with strict control of microorganisms and endotoxins.

A variety of options: xanthan gum has ordinary type and transparent type, transparent type xanthan gum has good clarity and transparency after dissolution. Mixing xanthan gum and gum arabic will have better suspending effect.

Lower impurity residue: strictly control the residue of impurities and pollutants.

3. Product Application

Thickener:Because the tertiary structure of xanthan gum is a network structure, it has good thickening properties, especially high viscosity at low mass concentration.

Suspending agent:Xanthan gum has high viscosity, strong rheology and pseudoplasticity, good stability, acid and alkali resistance, so it can be used as a good suspending agent.

Stabilizer:Xanthan gum can be used as a stabilizer in a variety of suspending agents and emulsifiers, such as vitamin emulsifiers to avoid stratification due to temperature elevations.

Adhesive:The good adhesion of xanthan gum makes it compatible with various excipients to prepare sustained-release tablets with different hardness, dissolution rate and viscosity, which is suitable for water-soluble and water-insoluble drugs.
