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. Mineral Powder Pigments such as oxides, ultramarines and micas are cosmetic-grade. These pigments are mined from the earth (inorganic), processed and filtered to remove harmful impurities such as lead or mercury. They are approved for use in soap, mineral cosmetics and cosmetic bases. Solubility: These are natural colour additives which are insoluble (they will remain suspended within the product and will not dissolve) in the formulation or product to which they are added. Unlike some liquid colours, they will not bleed or fade.
