Regulatory evidence across markets

None of the 13 markets tracked here holds an imported rule under the name TETRASODIUM PYROPHOSPHATE.

That is a statement about this inventory, not about the law: no imported rule is not evidence that a substance is permitted. A rule may exist under a different name, under a CAS or EC number this glossary entry does not carry, or in a dataset not yet imported.

Tetrasodium Pyrophosphate

Sodium diphosphate is an inorganic sodium salt comprised of a diphosphate(4) anion and four sodium(1+) cations. More commonly known as tetrasodium pyrophosphate, it finds much use in the food industry as an emulsifier and in dental hygiene as a calcium-chelating salt. It has a role as a chelator, a food emulsifier and a food thickening agent. It contains a diphosphate(4-). — ChEBI
