Bisphenol M (BPM) in your home: a safety profile
Low risk for your homeNot medical or professional safety advice, and not a substitute for a qualified clinician — consult one. Full disclaimer →
(Your Household-specific data is limited; this page draws from human adult context.) Bisphenol M (BPM; CAS 13595-25-0) presents a low risk to human adults at current ambient exposure levels, which are expected to be lower than BPA exposures. BPM's estrogenic and antiandrogenic activity in in vitro systems is documented but in vivo human exposure studies are limited. BPM has been detected in human urine in biomonitoring studies, indicating real-world exposure pathways including food contact material migration, dust ingestion, and dermal contact. In the absence of IARC, EFSA, or EPA individual risk assessments, risk extrapolation relies on in vitro mechanistic data and the well-characterized BPA class framework. The limited reproductive and developmental in vivo toxicology database for BPM makes definitive human health assessment difficult at this time.

Regulatory consensus
3 regulatory and scientific bodies have classified Bisphenol M (BPM). The classifications differ — that's the data.
| Agency | Year | Classification | Notes |
|---|---|---|---|
| ECHA | 2022 | no carcinogenicity classification; bisphenol analog with estrogenic and antiandrogenic activity; increasing environmental detection as BPA alternative; not classified by IARC, EFSA, NTP, or US EPA | |
| EPA CTX / Genetox | — | Genotoxicity: negative (single report) (Ames: None, 0 positive / 1 negative reports) | |
| EPA CTX / Genetox | — | Genotoxicity: negative (single report) (Ames: None, 0 positive / 1 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.
