Abstract

The Expert Panel for Cosmetic Ingredient Safety (Panel) assessed the safety of Acetyl Glucosamine, Glucosamine, Glucosamine HCl, and Glucosamine Sulfate. Two of the ingredients, Acetyl Glucosamine and Glucosamine Sulfate, are reported to function in cosmetics as skin-conditioning agents, Glucosamine HCl is reported to function as a pH adjustor, and the function of Glucosamine in cosmetics is not reported. The Panel reviewed the available data and concluded that these glucosamine ingredients are safe in cosmetics in the present practices of use and concentration described in this safety assessment when formulated to be non-irritating.
