VeriMomБезопасен ли pei-1400 при беременности?
No harmonised reproductive classification was found for CAS 9002-98-6 (polyethyleneimine / PEI) in ECHA substance information, and there are no CIR or SCCS safety opinions or peer‑reviewed developmental/reproductive toxicity studies identifying prenatal hazards for the polymer. Available toxicology is largely in vitro (cytotoxicity) or biodistribution for PEI-modified nanoparticles, not developmental/teratogenic evidence, so default hazard/mechanism scores apply. (See ECHA substance page; PubMed cytotoxicity/nanoparticle studies). ([echa.europa.eu](https://echa.europa.eu/en/substance-information/-/substanceinfo/100.123.818?utm_source=openai))

- Безопасен ли pei-1400 при грудном вскармливании?
- No evidence found of reproductive or lactation-specific toxicity, no harmonised CLP (Annex VI) classifications, and no SCCS/CIR opinions restricting use in breastfeeding. Dermal/topical cosmetic use of a high‑molecular‑weight polymer like PEI would be expected to have negligible systemic absorption in adults, so exposure from typical topical use is scored as negligible.

- Безопасен ли pei-1400 для кожи малыша?
- No infant‑specific reproductive or developmental toxicity data were identified. PEI is a high‑molecular‑weight, highly cationic polymer; available data describe in vitro cytotoxicity and PEI as a surface‑active/biomedical transfection agent or nanoparticle coating rather than a developmental toxicant. For topical infant skin, the exposure score is increased by +1 (to 1) relative to adults because immature infant skin has higher permeability and surface‑area‑to‑weight; however there is no evidence that baby‑specific systemic hazard or mechanism applies.
