Ammonia caramel is the color the food industry lists as E150c. In our table it is moderate risk: it takes 15 points off the additive subscore, a third of a product's score (about 5 of the 100).
- The key finding, from EFSA: Group ADI 300 mg/kg bw/day for E150a-d, but a lower individual ADI of 100 mg/kg bw/day for E150c because of possible immune effects of its constituent THI. SUPERSEDED IN PART: the clause that combined mean intake for children exceeded the group ADI at maximum reported use levels is superseded by the 2012 refined assessment (refined combined means 12-105 mg/kg bw/day, all below 300). The individual-ADI half stands and is what this row's class and higher-concern-for-young-children flag rest on (10.2903/j.efsa.2011.2004)
- 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 up one class, to high risk.

What Ammonia caramel does to a score
A packaged food's additive subscore starts at 100 and loses points for each additive on the label; that subscore is a third of the final score. Ammonia caramel takes 15 points off the additive subscore, a third of a product's score (about 5 of the 100), 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.

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

EFSA
10.2903/j.efsa.2011.2004
Group ADI 300 mg/kg bw/day for E150a-d, but a lower individual ADI of 100 mg/kg bw/day for E150c because of possible immune effects of its constituent THI. SUPERSEDED IN PART: the clause that combined mean intake for children exceeded the group ADI at maximum reported use levels is superseded by the 2012 refined assessment (refined combined means 12-105 mg/kg bw/day, all below 300). The individual-ADI half stands and is what this row's class and higher-concern-for-young-children flag rest on. -
EFSA
10.2903/j.efsa.2012.3030
Refined exposure: toddlers exceed the E150c ADI of 100 mg/kg bw/day at the upper end of the 95th percentile. This is the age-group-specific basis for this row's higher-concern-for-young-children flag, and — via E 150c's dominance of resolved caramel occurrences — for the en:e150 parent's higher-concern-for-young-children flag too. -
OEHHA
Prop 65, 4-methylimidazole (listed as carcinogen 2011); NSRL 29 ug/day (oehha.ca.gov/sites/default/files/media/100711_4MEIfindings.pdf)
4-MEI, formed during manufacture of ammonia caramels, is a Prop 65 listed carcinogen with a No Significant Risk Level of 29 ug/day.
Why this class
IARC Group 2B; or an EFSA re-evaluation that flagged genotoxicity data gaps, found safety could not be assessed on the available data, or cut the ADI citing child exposure; or an EU harmonised classification of the substance as a reproductive or developmental hazard; or an EU withdrawal of one authorised food use while others remain; or an OEHHA/Proposition 65 listing; or membership of the Southampton-six colourants.
Our confidence in this row's classification is high. 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.
Questions parents ask
Is Ammonia caramel (E150c) safe for kids?
Moderate risk. In Sito it takes 15 points off the additive subscore, a third of a product's score (about 5 of the 100). It is flagged for young children, so for a child under 6 it moves up one class, to high risk: 30 points off the additive subscore. The finding we rely on: Group ADI 300 mg/kg bw/day for E150a-d, but a lower individual ADI of 100 mg/kg bw/day for E150c because of possible immune effects of its constituent THI. SUPERSEDED IN PART: the clause that combined mean intake for children exceeded the group ADI at maximum reported use levels is superseded by the 2012 refined assessment (refined combined means 12-105 mg/kg bw/day, all below 300). The individual-ADI half stands and is what this row's class and higher-concern-for-young-children flag rest on (EFSA, 10.2903/j.efsa.2011.2004).
What is E150c?
E150c is the E number for Ammonia caramel, a color. It is one of the forms of E150 (Caramel) in our table, with E150a, E150b and E150d. Open Food Facts tags it en:e150c.
