E172

E172 is a food additive approved by the European Union (EU).
It is used as a natural colouring agent in food and drink products.

The common name for E172 is iron oxides and hydroxides.

E172 is a red/brown colouring that is available in three forms:

  • E172(i) - black iron oxide,
  • E172(ii) - red iron oxide, and
  • E172(iii) - yellow iron oxide.

The iron is not actively absorbed by body tissue.
This colouring may act as an irritant when in dust form and is banned in Germany.

Examples of food/drink products that may include E172:
Salmon and shrimp pastes, meat pastes, cake and dessert packets and soups.
