Additive Table / Potassium benzoate

Potassium benzoate (E212)

Potassium benzoate is the preservative the food industry lists as E212. In our table it is high risk: it takes 30 of the 33 additive points off a product's score for a child.

In short
  • High risk. 30 of the 33 additive points come off a product that carries it.
  • Flagged for young children. Set only where EFSA’s own exposure assessment shows toddlers or children exceeding or approaching the ADI, or where a regulator used explicitly child-specific language. For a child under 6 it moves one class up.

What Potassium benzoate does to a score

A packaged food starts with 33 points for what is in its ingredient list. Potassium benzoate takes 30 of the 33 additive points off a product's score, and a child under 6 sees it one class higher again. Scan the pack in Sito and the score you get is the one for your own child's age, with this additive named in the reasons. How we score has the whole method.

What the sources found

Every classification in our table comes from the citations below, and nothing else. They are quoted as the source wrote them.

  • EFSA 10.2903/j.efsa.2016.4433
    E212 is covered by the 5 mg/kg bw/day group ADI; exceedance identified specifically for toddlers and children.
  • Peer-reviewed McCann et al., Lancet 2007; doi:10.1016/S0140-6736(07)61306-3
    Benzoate-containing challenge mixes increased hyperactivity in 3-year-olds and 8/9-year-olds (mixture effect, not benzoate-specific).
  • Open Food Facts additives taxonomy node en:e212
    Cross-check only: OFF flags the same high overexposure risk with children/toddlers/infants among the exceeding groups.

Why this class

IARC Group 1 or 2A with a dietary exposure route; or EFSA has withdrawn or negated a safety conclusion; or EFSA’s own exposure assessment finds a child age group exceeding the ADI at mean intake; or the substance is banned or formally being phased out for food use by the EU, by the US FDA, or under a US state law.

Our confidence in this row's classification is medium. Medium or low does not mean the evidence is weak; it means something about the row is still being pinned down, usually a regulatory status confirmed from one source rather than two.

Scan a packaged food and Sito names the additives in it, then scores the product out of 100 for your child's age.
