Is Ci 77499 Safe in Makeup?

Yes, Ci 77499 is safe for most people. This black iron oxide pigment is one of the most stable and well-tolerated colorants in cosmetics.

Ci 77499 is essentially rust in its purest form — triiron tetraoxide that's been purified for cosmetic use. It's found in 129+ products on our site, from eyeshadows to foundations, providing rich black pigmentation without penetrating the skin barrier.

The EU lists it under restriction IV/137, which simply means it must meet purity standards for cosmetic use — not a safety concern. Iron oxides are considered among the safest colorants available, with decades of safe use data.

Who should avoid it: People with rare iron oxide allergies may experience irritation, though this affects less than 1% of users.

Unlike synthetic dyes that can cause staining or sensitivity, Ci 77499 sits on the skin's surface and washes off easily. It's particularly prized in clean beauty formulations as a natural alternative to synthetic black dyes.
