Frequently asked questions
- Is octadecane safe during pregnancy?
- Octadecane (C18 alkane) has no harmonised reproductive classification in ECHA Annex VI, no SCCS/CIR safety concern identified, and there are no published reports of reproductive or developmental toxicity in humans or animals in available regulatory databases. Physicochemically it is an inert long‑chain hydrocarbon with no known reproductive mechanism (sources: ECHA Annex VI — no harmonised classification; PubChem; CosIng).
- Is octadecane safe while breastfeeding?
- No data indicate reproductive or lactation-specific toxicity or mammary transfer. No harmonised flags or CIR/SCCS opinions raising concern. As a long‑chain alkane, there is no evidence of endocrine activity or proven mechanism that would affect breastfeeding (sources: ECHA Annex VI; PubChem; CosIng).
- Is octadecane safe for baby skin?
- Hazard and mechanism: no infant‑specific reproductive/toxic evidence found. Exposure: adult dermal absorption from long‑chain alkanes is expected to be negligible, but because infants (0–3 yr) have a less mature skin barrier and higher surface‑area‑to‑body‑weight, exposure rating is increased by +1 to reflect low but measurable potential dermal uptake when used topically. No data justify increasing hazard or mechanism scores (sources: general inhalation/dermal profiles in PubChem; CosIng; ECHA registration dossiers/no harmonised classification).
- How does VeriMom score octadecane?
