Iron Oxide Yellow (17049)

Iron Oxide Yellow (17049) is a fine, yellow powder that is insoluble in water and various solvents. It is produced by the controlled oxidation of iron, resulting in the formation of iron oxide particles with a bright yellow hue. The pigment is highly stable and resistant to light and chemical reactions, making it suitable for a wide range of industrial and cosmetic uses.
