VeriMomБезопасен ли quaternium-91 при беременности?
No harmonised reproductive classifications (ECHA Annex VI) or CIR/SCCS safety opinions specifically flagging reproductive risk for quaternium-91; no peer-reviewed reproductive or developmental toxicity reports were identified in PubMed. Dermal absorption for quaternary ammonium salts is generally low but not zero, so low but measurable exposure is retained for topical use (PubChem/ECHA dossiers indicate typical physico‑chemical properties of quaternary ammonium compounds). Sources searched: ECHA Annex VI, PubChem, CIR, PubMed, CosIng, EWG.

- Безопасен ли quaternium-91 при беременности?

- Безопасен ли quaternium-91 при грудном вскармливании?
- Same rationale as pregnancy: no evidence of reproductive or lactation-related toxicity or harmonised hazard. Systemic uptake from normal cosmetic topical use is expected to be low but measurable, so potential for minimal maternal exposure exists; no specific data on milk excretion were found.
- Безопасен ли quaternium-91 для кожи малыша?
- No infant-specific reproductive/toxicity data located. Following the instruction to increase exposure by +1 for baby skin where adult absorption is measurable, exposure is rated higher for 0–3 yr due to immature barrier and higher surface‑area‑to‑weight; no evidence was found indicating increased hazard or a specific mechanism in infants.
