FDA also includes xanthan gum on its list of indirect food additives for use in polymers that come in contact with food.
Expert Panel for Cosmetic Ingredient Safety
The safety of xanthan gum and biosaccharide gum-1 has been reviewed by the Expert Panel for Cosmetic Ingredient Safety. The Expert Panel reviewed the scientific data and concluded that these ingredients were safe as used in cosmetics and personal care products.
Based on the large molecular weights, the Expert Panel determined that xanthan gum and biosaccharide gum-1 would not be absorbed through the skin. The Expert Panel reviewed data that indicated that xanthan gum was not a reproductive or developmental toxicant. Studies of other polysaccharide gums did not reveal a genotoxic effect. Xanthan gum and biosaccharide gum-1 were not considered to be dermal irritants or sensitizers.
Based on the available data on xanthan gum and other polysaccharide gums, the Expert Panel concluded that xanthan gum and biosaccharide gum-1 were safe as used in cosmetic products. Xanthan gum is identified in 21 CFR 172.695 as a food additive that may be safely used following prescribed conditions.
