FAQ
- Is methyl morpholine oxide safe during pregnancy?
- ECHA lists 4‑methylmorpholine 4‑oxide (N‑methylmorpholine N‑oxide; CAS 7529‑22‑8) with a harmonised CLP reproductive hazard H361f (suspected of damaging fertility), which supports a suspected reproductive hazard (h=2). A specific molecular mechanism for reproductive effects is not described in available dossiers, so mechanism is scored as theoretical/uncertain (m=1). For typical topical cosmetic use dermal exposure is low but measurable (hydrophilic substance, low logP), so adult exposure is scored low (e=1). Sources: ECHA classification and supplier/MSDS listings.
- Is methyl morpholine oxide safe while breastfeeding?
- Harmonised H361f (ECHA) applies to general reproductive/fertility concern and is the principal driver (h=2). No clear data on mammary/milk transfer or neonatal toxicity were found; mechanism remains uncharacterized (m=1). Given the compound's hydrophilicity and expected low dermal/systemic absorption from cosmetics, exposure via topical maternal use is judged low (e=1), but milk transfer data are lacking.
- Is methyl morpholine oxide safe for baby skin?
- Hazard remains driven by harmonised H361f → h=2. Mechanistic evidence is lacking (m=1). Because infant skin (0–3 yr) has higher surface‑area‑to‑weight and an immature barrier, exposure score is increased by +1 compared with adult (adult e=1 → baby e=2) where measurable dermal absorption is plausible. No infant‑specific toxicity or exposure studies were found.
