Who it's for
Description
Black Iron Oxide is the super common inorganic (as in no carbon atom in the molecule) pigment that controls the darkness of your foundation or gives the blackness to your mascara. Blended with red and black iron oxides, it is essential in all "flesh-toned" makeup products.
Chemically speaking, it is a mixture of iron II and iron III oxide. Btw, this guy, unlike the yellow and red pigments, is magnetic.
