Chromium Oxide Greens

What is Chromium Oxide Greens?

Chromium Oxide Greens is a synthetic inorganic pigment, chemically known as chromium(III) oxide (Cr₂O₃), produced through high-temperature calcination of chromium compounds. It manifests as a fine, brilliant green powder prized for its high opacity and lightfastness in cosmetics. Primarily employed in eye area makeup like eyeshadows and liners, facial powders, and hair coloring formulations, it imparts a vivid green shade without bleeding or migrating. As an insoluble pigment, it disperses uniformly in bases to ensure batch-to-batch color consistency and durability during wear. In hair products, it contributes to direct dye systems for temporary color effects. Its chemical stability prevents interactions with formulation components, making it suitable for long-shelf-life products. Regulatory bodies affirm its use in cosmetics when properly purified and incorporated.
