Iron Oxide (E 172)
Iron Oxides are found naturally in the world but are full of impurities
and cannot be purified. Therefore all Iron Oxides used in the food
industry are produced synthetically. They are generally micronized
to produce a very fine particle size. They are totally insoluble
in all generally used food products.

Black Iron Oxides are very stable inorganic pigments but tend to
be rather dull in appearance. They can be easily blended into dry
mixtures or dispersed into a variety of aqueous or oil based liquid
mediums. Most commonly used in combination with Yellow and Red
Iron Oxide to give a variety of brown shades.
Iron Oxides are used widely in the pet food industry and where
high stability to processing conditions is required.
