What is Iron Oxide Black (Black Oxide)?
Iron Oxide Black, commonly known as Black Oxide (Fe₃O₄), is a deep black inorganic pigment known for its excellent opacity, UV resistance, and chemical stability. It is used in a wide range of industries including paints, coatings, plastics, construction, ceramics, and cosmetics.
This pigment is non-toxic, heat-stable, and weather-resistant, making it suitable for both interior and exterior applications. In the cosmetics world, it is often used in eyeliners, mascaras, and foundations due to its intense color and safe profile. Its strong tinting strength and dispersibility also make it a preferred pigment in heavy-duty industrial formulations.
