10.2903/j.efsa.2018.5373 (EFSA Journal 2018 — Refined exposure assessment of extracts of rosemary (E 392))
Against JECFA's temporary ADI of 0–0.3 mg/kg bw (as carnosic acid + carnosol), the highest refined mean exposure was 0.09 mg/kg bw/day in children (3–9 y) and the highest P95 0.20 mg/kg bw/day in children; the Panel considered these very likely to overestimate real exposure, and margins of safety improved on the 2015 assessment.
Why this class
Clean current EFSA and FDA status. These rows exist so that an unfamiliar additive is never treated as a bad one: a missing row costs a product nothing, and a clean row says so with citations.
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.
