Xanthan Gum – Cosmetic Uses in Skin Care and Personal Care Products

What Is Xanthan Gum?

Xanthan Gum is a high-molecular-weight natural carbohydrate, more specifically a polysaccharide, produced through a fermentation process. It is also sometimes referred to as corn sugar gum.

It is listed as an ingredient in the British Pharmacopoeia and is also widely used in food products. In cosmetic formulations, Xanthan Gum is valued for its ability to modify viscosity and texture while providing a distinctive lubricious feel.

Cosmetic Applications

Xanthan Gum is used to modify the texture and consistency of a wide range of personal care products. It can also help stabilise formulations against separation.

Its applications include:

• Skin care products
• Creams and lotions
• Makeup products
• Toothpaste
• Suspensions
• Oil-in-water emulsions
• Foaming products

Viscosity and Stabilisation

Xanthan Gum produces relatively high viscosity at low shear rates. This helps keep particles suspended and reduces the tendency of oil droplets to coalesce in emulsions.

One of its useful formulation properties is its shear-thinning behaviour. When force is applied, such as during pouring, squeezing, or spreading, the viscosity decreases, making the product easier to dispense and apply.

Once the applied force is removed, the solution rapidly regains much of its initial viscosity. This property contributes to both formulation stability and desirable application characteristics.
