VeriMomIs nonan-3-one safe during pregnancy?
No harmonised CLP classification, no SCCS or CIR reproductive safety assessment located, and no peer‑reviewed evidence of teratogenic or reproductive effects was found in the searches; therefore default hazard/mechanism scores are 0. Dermal/topical absorption of a small aliphatic ketone like nonan‑3‑one is low but measurable, so exposure is scored as 1 for pregnant users. Sources searched include ECHA (EC inventory/brief profile) and PubChem which list the substance but show no harmonised reproductive classification or regulatory reproductive warnings.

- Is nonan-3-one safe while breastfeeding?
- Same rationale as pregnancy: no authoritative evidence (harmonised CLP, SCCS, CIR) of reproductive or lactation-specific hazard or mechanism. Topical absorption is low but measurable for this small ketone, so breastfeeding exposure scored 1. No data were found showing transfer into breastmilk or adverse effects in breastfed infants.

- Is nonan-3-one safe for baby skin?
- No infant‑specific reproductive/toxicity data or harmonised classification found. Per the requested scoring rules, measurable adult dermal absorption (e=1) is increased by +1 for infants (0–3 yr) because of immature barrier and higher surface‑area:weight, producing e=2. Hazard and mechanism remain 0 absent any infant‑specific adverse data.
