Regulatory consensus
3 regulatory and scientific bodies have classified Toluene diisocyanate (TDI) or MDI (in 1K moisture-cure formulations). The classifications differ — that's the data.
| Agency | Year | Classification | Notes |
|---|---|---|---|
| EPA CTX / NTP RoC | — | Reasonably Anticipated to be a Human Carcinogen | |
| EPA CTX / Genetox | — | Genotoxicity: positive (Ames: positive, 5 positive / 5 negative reports) | |
| EPA CTX / Genetox | — | Genotoxicity: positive (Ames: positive, 5 positive / 5 negative reports) |
Regulators apply different standards of evidence — animal-data weighting, exposure-pattern assumptions, epidemiological power thresholds — which is why two scientific bodies can review the same data and reach different conclusions. The disagreement is the data.
