C.I. 77492

What is C.I. 77492?

C.I. 77492 is a synthetic inorganic pigment known as yellow iron oxide or ferric oxide yellow, with the chemical composition primarily iron (III) oxide hydrate (FeO(OH)). It originates from controlled high-temperature calcination of iron salts, ensuring purity for cosmetic use. Commonly found in makeup products like foundations, blushes, and eyeshadows, it functions as a colorant by dispersing evenly to deliver opaque yellow tones. Its particulate nature allows for blendable coverage without bleeding, and it offers excellent lightfastness and chemical stability, resisting degradation from formulation ingredients or environmental factors. This makes it ideal for long-wear applications across various product textures.
