E216PreservativeModerate concern
Propylparaben
In plain words
The short version
Propyl 4-hydroxybenzoate — de-listed in EU food in 2006 over endocrine concerns; still in use elsewhere.
Why we flag it amber
It's permitted and generally considered safe, but there are a few reasons to be mindful — like sensitivities in some people, debated studies, or intake limits. The Safety section below explains the specifics.
Safety profile
ADI of 0–2 mg/kg body weight (where still permitted, EFSA's pre-revocation level). Weakly estrogen-receptor active in vitro at high concentrations — the human-dietary relevance triggered the EU revocation as a precaution.
