Iron oxides are chemical compounds composed of iron and oxygen. Oxides (clay containing ferric oxide) are extracted from quarries. Iron Oxides yield deeper tones. Matte and opaque finish. Our range of oxides can be used alone or added to other colours to deepen the tone. Use these for tinting foundations, blushers, eyeshadows, eyeliners, lip colours and pretty much anything you can dream up. These pigments are essential to makeup formulators.
