Xanthan Gum is a polysaccharide of bacterial origin. Made by fermentation of glucose and sucrose by Xanthomonas campestris. In food it is a thickener (E415), in cosmetics a thickener and stabiliser. Mechanism. Forms pseudoplastic gels – thick at low load, fluid under shear (rubbing) for easy spread. Ideal for gels, serums, shampoos where stable texture is needed. Holds pigment and particle suspensions (important for foundations and mineral-filter sunscreens). Where applied. In virtually any cosmetic with a gel or cream texture – concentrations 0.1-2%. In Spain – massively in Caudalie, Bioderma, La Roche-Posay, Avène, ISDIN. Also in shaving gels, shampoos, toothpaste. Evidence base. Functional ingredient. CIR confirmed safety across the full concentration range in 2008. Safety. Inert to the skin. Non-sensitising, non-comedogenic. Safe in food and cosmetics for over 50 years. Pregnancy and lactation – safe. Usable without restrictions. Also safe in the diet of pregnant women.
