IARC (International Agency for Research on Cancer)1
IARC Group 3 — Not classifiable as to carcinogenicity. The available evidence is insufficient for a classification. This does NOT mean 'safe'; it means 'not enough data'. (Monograph volume: 36, Sup 7, 71). Caveat: IARC classifies HAZARD, not RISK — it says 'can cause cancer under some conditions', not 'causes cancer at cosmetic use levels'. Route and dose must be assessed separately. Data is a 01/2021 snapshot.
