Is Ci 77492 Safe in Makeup?

Yes, Ci 77492 is safe for most people. This iron oxide is one of the most widely used and well-tolerated colorants in cosmetics, giving makeup that warm yellow undertone you see in foundations, eyeshadows, and bronzers.

Ci 77492 is essentially rust — iron oxide that's been purified for cosmetic use. It's naturally occurring, non-comedogenic, and rarely causes irritation or allergic reactions. The EU regulates it under restriction IV/136, which means it meets strict safety standards for use in cosmetics.

Who Should Be Cautious

People with severe metal allergies might want to patch test first, though reactions to iron oxides are extremely rare. Those with very sensitive skin can typically use products containing Ci 77492 without issues.

You'll find this ingredient in 127 products on ShadeVault, from drugstore foundations to luxury eyeshadow palettes. Unlike some synthetic dyes that can cause staining or irritation, iron oxides like Ci 77492 are among the gentlest colorants available.

Bottom line: Ci 77492 is one of the safest coloring agents in your makeup bag.
