Science
Mechanism of Action
This ingredient operates by forming a robust, gel-like matrix within aqueous systems. This matrix effectively prevents phase separation in emulsions, ensuring uniform distribution of active ingredients, thereby supporting overall formulation stability and enhancing the tactile experience of the product.

Formulation
Stability
Xanthan gum solutions, as the parent compound, maintain stable viscosity with less than 10% change across a wide pH range of 3-11, with optimal stability observed between pH 5 and 10. It exhibits consistent viscosity across varying temperatures, offers excellent freeze-thaw stability, and demonstrates high resistance to enzymatic degradation, salts, acids, and bases.
Conflicts
- Generally incompatible with cationic surfactants, polymers, or preservatives, which may lead to precipitation.
- Certain acid modifiers (e.g., citric, malic, succinic, fumaric acids) can catalyze cross-linking in powder blends during accelerated stability studies, potentially reducing viscosity and suspendability.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed Hydroxypropyl Xanthan Gum safe for use in cosmetics under current practices and concentrations. It is generally recognized as non-toxic, non-irritating, and non-comedogenic at typical usage levels. However, individuals with highly sensitive skin or known allergies to corn, soy, or wheat (potential fermentation sugar sources) should consider patch testing due to rare reports of mild irritation or allergic reactions.
