EU regulatory and ECHA data show tobacco extracts (84961-66-0) contain nicotine and registrants/notifications classify the substance for acute toxicity; nicotine has an EU harmonised classification (see ECHA) and is listed in Annex II (prohibited in cosmetics), therefore pregnancy hazard is 'suspected' (h=2). Mechanistically, nicotine is a demonstrated reproductive toxicant that crosses the placenta and has developmental effects in animal/human exposure contexts (m=2). Dermal exposure from cosmetics is plausible because nicotine is readily absorbed through skin (transdermal patches demonstrate systemic delivery), so exposure from topical products is moderate (e=2). Sources: ECHA tobacco extract and nicotine pages, CosIng entry, and clinical/pharmacokinetic studies on transdermal absorption and nicotine transfer to fetus/breastmilk.

- Безопасен ли nicotiana tabacum leaf oil при грудном вскармливании?
- Nicotine is known to be excreted into breast milk and breastfed infants are exposed when the mother uses nicotine-containing products; because tobacco extracts contain nicotine and nicotine has harmonised reproductive classification, breastfeeding is a suspected hazard (h=2). Mechanism: demonstrated transfer into milk and pharmacologic effects on infants (m=2). Exposure from topical use is measurable (transdermal absorption evidence), so breastfeeding exposure is assessed as moderate (e=2).
- Безопасен ли nicotiana tabacum leaf oil для кожи малыша?
- Hazard remains 'suspected' (h=2) because the extract contains nicotine (harmonised reproductive concern / EU prohibition for nicotine). Mechanism same (nicotine systemic/ developmental effects) (m=2). Exposure score increased for baby skin: infants have higher surface-area-to-weight and thinner barrier, and nicotine is transdermally absorbable (patch data); therefore exposure is elevated (adult e=2 → baby e=3).
