VeriMomБезопасен ли methylmethionine при беременности?
No harmonised CLP reproductive classification or SCCS/CIR safety assessment was found for S‑methylmethionine (CAS 4727‑40‑6). Available literature treats the substance as a plant/food metabolite (Vitamin U) and reports physicochemical properties consistent with a small, highly polar zwitterionic/sulfonium amino‑acid derivative (low logP), so there is no evidence of reproductive hazard or a known reproductive mechanism from searched sources (PubChem; PubMed). Absorption from topical cosmetic use is expected to be negligible based on polarity and low logP, so exposure is scored negligible.

- Безопасен ли methylmethionine при грудном вскармливании?
- No data indicating reproductive or lactation-related hazard; no mechanistic or animal/human data showing transfer to milk or effects on lactation were found in the searched databases. Physicochemical profiles (high polarity, low logP) predict low dermal/systemic absorption after cosmetic topical use; therefore hazard and mechanism are scored 0 and exposure negligible.

- Безопасен ли methylmethionine для кожи малыша?
- No infant-specific toxicity or developmental dermatology data were identified. Because the compound is polar with low predicted dermal penetration (PubChem data), adult topical exposure is negligible; per the scoring rules, baby exposure is increased by +1 to account for immature barrier and higher SA:BW when an ingredient has measurable (although low) absorption potential. No evidence was found to raise hazard or mechanism scores. ([pubchem.ncbi.nlm.nih.gov](https://pubchem.ncbi.nlm.nih.gov/compound/4727-40-6?utm_source=openai))
