The Expert Panel for Cosmetic Ingredient Safety (Panel) reviewed the safety of five Equisetum arvense–derived ingredients as used in cosmetic products; all of these ingredients are reported to function as skin-conditioning agents in cosmetics. Industry should use current good manufacturing practices to minimize impurities that could be present in these botanical ingredients. The Panel reviewed data relevant to the safety of these ingredients in cosmetic formulations, and concluded that the five Equisetum arvense–derived ingredients are safe in cosmetics in the present practices of use and concentration described in this safety assessment.
