What The Sources Say
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: 8, Sup 7). 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.
ToxValDB (EPA Toxicity Value Database)2
EPA ToxValDB kanser değerlendirmesi: 3 - Not classifiable as to its carcinogenicity to humans. Caveat: this is an aggregated record; dose, species and route of exposure must be considered together.
EPA ToxValDB genotoxicity: positive — positive reports: 32, negative: 12, Ames: positive, micronucleus: positive. Caveat: this is an aggregated record; dose, species and route of exposure must be considered together.
EPA ToxCast (high-throughput in vitro screening)1
EPA ToxCast ER model: NO estrogen receptor activity found (AUC agonist=0, antagonist=0). Tested in 18 in vitro assays. Caveat: this is an in vitro screening model with no dose or exposure context; it does NOT mean an effect occurs in humans at cosmetic use levels.
