Iron Oxide Yellow CI 77492 (Yellow Iron Oxide)

Iron Oxide Yellow (CI 77492) is an inorganic mineral pigment widely used in cosmetic formulations to provide stable yellow-to-golden coloration and to fine-tune undertones in blended shade systems. Valued for its excellent lightfastness, chemical stability, and reliable opacity, it delivers consistent color payoff and helps create warm, natural-looking hues—especially when combined with CI 77491 (red) and CI 77499 (black) iron oxides for complexion matching. As an insoluble pigment, it also contributes to optical coverage and a smoother, more even-looking finish when properly dispersed in powders, waxes, oils, and emulsions. Iron Oxide Yellow (CI 77492) is commonly found in foundations, concealers, powders, bronzers, blushes, eyeshadows, lip products, and tinted skincare, typically used at low to moderate levels depending on the desired shade depth, coverage, and undertone.
