Is Iron Oxides banned?
Iron Oxides is permitted by the US FDA. Several countries restrict, warning-label, or have reviewed it for safety concerns. The US has more lenient additive rules than the EU, UK, Canada, and Japan, which is why this ingredient remains widely used here.
Why Iron Oxides is flagged
Cosmetic-grade iron oxides are among the safest colorants used in personal care products. They are inert, non-reactive, non-carcinogenic, and non-irritating. They do not penetrate intact skin. FDA and EU have approved them for use in a wide range of cosmetic applications including eye area products. The key safety requirement is that cosmetic-grade iron oxides must be synthetically produced (not mined) to ensure they are free from harmful heavy metal contaminants.
