Chromium Green Oxide – Cosmetic Grade Colourant for Soap & Makeup Chromium Green Oxide is a rich, earthy green pigment perfect for cold process soap, mineral makeup, and cosmetic formulations. With excellent stability and high tint strength, this oxide delivers consistent colour in both DIY and commercial applications. For soap making, we recommend diluting the oxide in a small amount of glycerine or oil to prevent clumping and achieve a smooth blend. This ensures even colour dispersion throughout your batch.
