What is it?
Iron Oxides (CI 77491, 77492, 77499) are naturally occurring mineral pigments commonly used in skincare and cosmetic products for coloring purposes. These compounds come in three main shades: red (CI 77491), yellow (CI 77492), and black (CI 77499), and can be combined to create a wide range of colors. Iron Oxides are known for their stability, non-toxicity, and non-reactive properties, making them ideal for use in makeup formulations, such as foundations, blushes, and eyeshadows.
Where does it come from?
Iron Oxides are derived from natural minerals found in the earth's crust. However, for cosmetic and skincare use, they are purified to ensure consistency and safety to eliminate any potential contaminants and provide standardized shades that are safe for use on the skin. This process also ensures that Iron Oxides used in cosmetics are free from heavy metals, making them suitable for sensitive skin.
