Xanthan Gum – The “Invisible Assistant” in Food and Personal Care

Xanthan Gum (XG) is a natural polysaccharide produced by microbial fermentation. Since its commercialization in the 1960s, it has become one of the most recognized and versatile biogums worldwide. Safe, non-toxic, and highly efficient, Xanthan Gum is widely applied in food, cosmetics, pharmaceuticals, and more.

1. Why is Xanthan Gum “low-key but powerful”?

In appearance, Xanthan Gum is a light yellow or off-white powder that dissolves in water to form a colloidal solution. Its unique advantages include:

• Excellent thickening ability: Even at low concentrations, it significantly increases viscosity—1% solution can be about 100 times thicker than gelatin.
• Outstanding stability: Resistant to acid, alkali, high salt, and high temperature; it remains stable even after freezing and thawing.
• Remarkable thixotropy: Under stirring or extrusion, viscosity decreases, but recovers when static—making products easier to process and improving texture.

These properties make Xanthan Gum an indispensable “structural supporter” in countless products.

3. Pharmaceuticals

3. Common Questions

• Is it safe? Yes. Approved by the U.S. FDA, Chinese GB2760, and other authorities, Xanthan Gum is safe for food and cosmetic use.
• Is it absorbed by the body? No. As a macromolecule, it stays on the surface to form a protective layer and is naturally excreted.
• Can sensitive users use it? Yes. Xanthan Gum is non-irritating and suitable for most skin types, including sensitive skin and infant products (within regulated limits).

4. Final Note

Xanthan Gum may not be the “star ingredient” in formulas, but it plays a vital behind-the-scenes role in maintaining stability, texture, and overall experience. Next time you see “Xanthan Gum” on an ingredient list, remember—it’s quietly working to enhance your food and skincare.
