FAQ

Is butyl methacrylate safe during pregnancy?
No harmonised reproductive classification in ECHA Annex VI for butyl methacrylate (harmonised CLP entries are H226, H335, H315, H319, H317 for the n‑butyl methacrylate monomer). PubChem aggregates include a non‑harmonised H361 (repro) flag, but that is an aggregated notification and not legally harmonised; therefore reproductive hazard is not confirmed. Dermal exposure from cosmetic topical use is likely low but measurable (monomeric methacrylates can penetrate skin), so exposure score is 1.
Is butyl methacrylate safe while breastfeeding?
No confirmed reproductive/mammary toxicant classification in harmonised CLP (ECHA Annex VI). There is no authoritative evidence of transfer in breastmilk or specific lactation toxicity; therefore hazard and mechanism scores are 0. Exposure via topical use during lactation is judged low but measurable.
Is butyl methacrylate safe for baby skin?
No infant‑specific reproductive or developmental hazard evidence and no harmonised repro classification. However, because infant skin has higher surface‑area‑to‑body‑weight and a more permeable barrier, the adult exposure score (1) is increased by +1 for baby skin, giving an exposure score of 2. Note that the substance is a known skin irritant and sensitiser (ECHA Annex VI), so topical use on infant skin could pose local irritation/sensitisation risks even if systemic reproductive risk is not established.
