CI 77492

CI 77492 is an iron oxide pigment, specifically iron oxide yellow. It is a naturally occurring or synthetically produced mineral compound used in cosmetics primarily as a colorant. Iron oxides have been used in colour cosmetics for decades and are approved for use in the EU, US and other regulated markets.In skincare products, CI 77492 is typically found in tinted formulations such as tinted moisturisers, BB creams, foundations and colour-correcting products. Its role is functional — to provide pigmentation — rather than therapeutic.

CI 77492 works as a colorant through light absorption and reflection. The iron oxide particles scatter and absorb light wavelengths, creating the yellow tone that blends with or neutralises other skin tones. It does not penetrate the skin; instead, it sits on the surface within the product formulation, providing visible colour correction or tint.

Products containing CI 77492 should be applied as directed on the product label — typically as part of a foundation, tinted moisturiser or colour-correcting product. Blend evenly for consistent coverage. If using multiple tinted products, test the combination on a small area first to ensure the shade matches your skin tone, as layering pigments can alter the final colour result.

Iron oxide pigments are generally well-tolerated and considered safe for cosmetic use. Those with very sensitive skin or a history of reactions to mineral pigments should patch-test first, though adverse reactions are uncommon.
