CI 77288 (Chromium Oxide Green)

CI 77288 is the Colour Index designation for chromium(III) oxide, an inorganic mineral pigment used in cosmetic formulations to deliver strong, stable green coloration. Valued for its excellent lightfastness, heat stability, and resistance to chemical change, it provides reliable, opaque color payoff and helps create a wide range of green-to-olive tones, especially when blended with iron oxides and titanium dioxide. As an insoluble pigment, it also contributes to a smooth, even-looking finish and consistent shade performance when properly dispersed in oils, waxes, and powder bases. CI 77288 is commonly found in eyeshadows, eyeliners, brow products, face powders, nail products, soaps, and specialty color cosmetics, typically used at low to moderate levels depending on the desired depth, opacity, and undertone.
