2-Phenylphenol: Why SCCS and EFSA Safety Records Diverge

2-Phenylphenol is flagged in the cross-vertical regulatory-gap output because the same CAS record (90-43-7) has different no-observed values in SCCS-family and EFSA source records. The lead row compares rat oral data in mg/kg bw/day.

What Each Source Says

The EFSA-side value in the lead row is 39 mg/kg bw/day. The SCCS-family value in the same matched comparison is 10000 mg/kg bw/day. The finding states that the EFSA no-observed value is lower than the SCCS-family no-observed value for the same CAS, species, route, and unit.

That match condition is important. This is not a broad statement that every safety endpoint for 2-Phenylphenol disagrees. The finding is narrower and stronger: the comparison holds within the normalized species, route, and unit keys shown in the table.

Why It Matters for Formulators

For cosmetic formulation, the SCCS-family record is the more directly cosmetic source. EFSA data, however, can still matter when the same chemical identity appears across food, pesticide, or other exposure contexts. A lower EFSA no-observed value does not automatically rewrite a cosmetic opinion, but it does mark a substance that deserves careful source-by-source review.

The practical takeaway is to avoid collapsing all NOAEL values for 2-Phenylphenol into a single number. The source corpus, study type, species, route, and endpoint context all carry weight. A one-number summary would hide the divergence that makes this substance worth checking.

What Not to Infer

This divergence row is not a standalone ban, approval, or reformulation deadline. It is a source-comparison signal. The correct inference is narrower: for 2-Phenylphenol, one matched EFSA no-observed value is lower than one or more matched SCCS-family values under the same normalized comparison keys. That is enough to justify review, but not enough to replace the underlying source documents.

The page is therefore useful as a map, not a verdict. It points to the precise mismatch a reviewer should investigate: chemical identity, endpoint value, route, species, unit, and source corpus. Those details are the difference between a real regulatory divergence story and a vague claim that two authorities disagree.

If a brand is using 2-Phenylphenol globally, this kind of cross-source mismatch is where review time should go first. A single cosmetic formulation may be legal and still deserve a closer toxicology note when another major source corpus reports a lower point of departure for a matched comparison.

The safest editorial wording is therefore specific: this page compares records, not countries. The source labels, values, and normalized matching keys are shown so the claim stays tied to the evidence that created the divergence flag.
