Safety Assessment of Fatty Acid Amidopropyl Dimethylamines as Used in Cosmetics

The Cosmetic Ingredient Review Expert Panel (Panel) reviewed the safety of fatty acid amidopropyl dimethylamines, which function primarily as antistatic agents in cosmetic products. The relevant animal and human data reviewed for these ingredients indicate that they are potential dermal sensitizers that may be due in part by the sensitizing impurity, 3,3-dimethylaminopropylamine. The Panel concluded that fatty acid amidopropyl dimethylamines were safe as cosmetic ingredients when they are formulated to be nonsensitizing, which may be based on a quantitative risk assessment.
