Iron oxide pigments used in food, pharmaceutical, cosmetics and make-up Coloring required stable performance, non-toxic, odorless, tasteless, the human body does not absorb, no side effects limited dose, non-oil permeability, do not damage the skin, the color of long exposure the same can be durable, meet the health requirements of the pharmacopoeia of medications, arsenic salt is less than l 5PPM, cobalt salt is less than 30PPM, barium salt were negative.
The US Food and Drug Administration requiring the use of synthetic chemicals, and the cobalt content is lower 10PPM, the mercury content of less than 3PPM, arsenic content is less than 3PPM, antimony content of less than 2PPM. All kinds of heavy metal content requirements very strict control.
This is the type of iron oxide pigments is ideal colorant of medicine, pills, capsules, Available for Dan, Rob sheet Well, NMT, compound Jiangyaling, liver tablets, vitamin Ei six should be pills, nourishing the nerves, ferrous sulfate tablets.

Iron oxide for cosmetic production, the raw materials must be purified to remove As, Pb and other impurities harmful to the skin, and the high purity requirements.
US FDA requirements already mentioned above, while the EU more specific requirements: water-soluble composition: <1.0%, As <3PPM, Ba <50PPM, Z50PPM, Cr <100PPM, Pb <10PPM, Cd <1 OPPM ', Cu <200PPM, n <1 0 oP PM.
