Compatibility
Works well with:
Glycerin Hyaluronic Acid Niacinamide Aloe Vera Panthenol Carbomer Hydroxyethylcellulose Guar Gum Sodium Chloride (low levels)
Use caution with:
High Electrolyte Concentrations Cationic Surfactants High Alcohol Concentrations Cationic Polymers
High concentrations of salts and electrolytes can disrupt the hydration shell of xanthan gum, causing viscosity loss or precipitation. Cationic surfactants and cationic polymers (e.g., polyquaterniums) can interact electrostatically with the anionic xanthan backbone, leading to complexation and phase separation. Alcohol concentrations above ~50% can cause precipitation or significant viscosity reduction.
Formulation notes
Disperse in water slowly with agitation to prevent clumping; pre-mixing with glycerin aids hydration. Pseudoplastic (shear-thinning) rheology makes it excellent for pump and spray formulations. Generally regarded as safe; no significant regulatory restrictions in cosmetics at typical use levels.
