Ultramarine Blue Pigment Oxide Mineral Powder Mineral Powder Pigments such as oxides, ultramarines & micas are cosmetic-grade. These pigments are mined from the earth (inorganic), processed & filtered to remove harmful impurities such as lead or mercury. They are approved for use in soap, mineral cosmetics & cosmetic bases. Ultramarine pigments cannot be used in bath bombs or any other products containing citric acid. Our range of oxides can be used alone or added to other colours to deepen the tone. Use these for tinting foundations, blushes, eyeshadows, eyeliners, lip colours & pretty much anything you can dream up. These pigments are essential to makeup formulators. Recommended usage: Using scales is recommended for larger batches. Please do small test batches as some of the colours are unstable in cold process soap. We recommend dispersing the powders into a small amount of your base first, then add to the remaining product & stir well. It is a good idea to wear a mask, goggles/glasses & protective clothing/apron as working with volatile powders is messy. Make sure you work in a well-ventilated area.
