FAQ

Безопасен ли methenamine при беременности?

Methenamine is listed with a harmonised/suspected reproductive hazard (H361) in ECHA materials and registration/brief-profiles, so reproductive hazard is 'suspected' rather than confirmed. Human pharmacokinetic data show methenamine crosses the placenta (measured in umbilical cord blood and amniotic fluid), demonstrating placental transfer. For topical cosmetic use, systemic exposure is expected to be low but measurable (cosmetic dermal exposures estimated and CIR/Canada assessments indicate low risk at typical cosmetic concentrations). Sources: ECHA classification summary; human study showing placental passage; CIR/Canada cosmetic assessments.

Безопасен ли methenamine при грудном вскармливании?

Harmonised/suspected reproductive classification (H361) supports 'suspected' hazard. Human data demonstrate methenamine is present in breast milk at concentrations similar to maternal plasma, showing demonstrated mechanism of transfer. However, for topical cosmetic use expected systemic absorption (and milk transfer) is low but measurable. Sources: ECHA classification; PubMed human milk data; CIR/Canada safety summaries.

Безопасен ли methenamine для кожи малыша?

Hazard remains 'suspected' (H361). Mechanistic concern is supported by demonstrated maternal→fetal/milk transfer in humans (relevant to infant exposure). Exposure (e) is increased for baby skin relative to adult because infants have a higher surface-area-to-weight ratio and an immature barrier; adult topical e is low but measurable, so baby skin exposure is scored one tier higher. CIR/Canada reviews found cosmetic uses safe only at low concentrations (e.g., CIR cited 0.16% max to limit formaldehyde release).
