Namely Xanthan gum is used in cosmetics as an emulsion stabilizer, film-forming agent or binder. It is obtained by the fermentation of a carbohydrate (for example glucose) with the bacterium Xanthomonas campestris. It is authorized in Bio.

A 2016 study of the Cosmetic Ingredient Review (CIR) on microbial polysaccharide gums, of which Xanthan gum is a part, concludes that the ingredient is safe.

Note that Xanthan gum is not regulated in Europe. In the United States, the FDA limits its use to 6% of the total ingredients in cosmetics.
Its functions (INCI)
  • Binding agent : Allows the cohesion of different cosmetic ingredients
  • Emulsifying : Promotes the formation of intimate mixtures between immiscible liquids by modifying the interfacial tension (water and oil)
  • Emulsion stabilising : Promotes the emulsification process and improves the stability and shelf life of the emulsion
  • Gel forming : Gives the consistency of a gel to a liquid preparation
  • Skin conditioning : Keeps the skin in good condition
  • Surfactant : Reduces the surface tension of cosmetics and contributes to the even distribution of the product when it is used
  • Viscosity controlling : Increases or decreases the viscosity of cosmetics
This ingredient is present in 17.24% of cosmetics.
