Not so long ago, May 1, 2014 Kevin who is a research scientist, studied many beauty products like a bar of soap in the shower. This time he did research on science behind tattoos. He found out that present days’ companies used pigments that are made of ion oxides (rust) that account for the black, red and browns. The formulas are Iron Oxide Red: Fe2O3, Iron Oxide Black: FeO · Fe2O3, and Iron Oxide Yellow: FeO(OH). For more exotic colors, heavy metals were used such as cadmium (red, orange, yellow), zinc (yellow, white), and cobalt (blue). Zinc oxide an inorganic compound with the formula ZnO. ZnO is a white power that is insoluble in water, and it is widely used as an additive in numerous materials and products including rubbers. Cobalt metal formula: CoAl2O4. Cobalt used in electroplating because of its attractive appearance, hardness and resistance to corrosion ("IRON OXIDES." FAO JECFA
