Shop this ingredient →

Xanthan gum is a polysaccharide thickener used in cosmetic formulations to build viscosity and stabilise systems.

 

What is Xanthan Gum & why is it used?

Xanthan gum is used to thicken and stabilise formulations, particularly in aqueous systems.

QUALITY MATTERS

Why specification quality matters

High-quality cosmetic grade xanthan gum with verified viscosity performance (520 mPa·s), low moisture, and clean microbial profile, supporting consistent formulation performance. 

Solubility Water dispersible
Primary function Thickener
Use level 0.1–0.5%

Behaviour in formulations

Xanthan gum hydrates in water to form a gel structure that increases viscosity and stabilises systems.

Sensory notes

Xanthan gum creates a slightly gel-like, cushioned texture. At higher levels it may introduce drag or stringiness. Sensory outcome is formulation-dependent; bench testing is recommended.

Formulation considerations

PROCESSING
  • Pre-disperse in glycerin or propanediol to prevent clumping, then add to water phase with mixing.
COMPATIBILITY
  • Compatible with most cosmetic ingredients
  • Works with surfactants and emulsions
  • Suitable for a wide range of systems
pH
Stable across a wide pH range.
FORMULATION EXAMPLES

Gel system

  • Xanthan gum: 0.2–0.4%
  • Humectants: 3–5%
  • Water phase to 100%

Cleanser system

  •  Xanthan gum: 0.2–0.3%
  • Surfactants
  • Humectants

Use level considerations

Recommended range 0.1–0.5%
Suggested starting level 0.2–0.3% for most cosmetic formulations%

Typically used at 0.1–0.5% depending on desired viscosity.

Formulation summary

Xanthan gum is a high-efficiency thickener used to build stable gels and improve formulation structure.

Quality notes

High-quality cosmetic grade xanthan gum with verified viscosity performance (520 mPa·s), low moisture, and clean microbial profile, supporting consistent formulation performance.
