FAQ
- Is isopropyl thioxanthone safe during pregnancy?
- No harmonised reproductive classification (ECHA Annex VI) or SCCS/CIR safety assessment was identified. Database entries (ECHA C&L notifications and PubChem GHS aggregations) list H361/H361F as non‑harmonised notifications, which alone do not justify a reproductive hazard classification. No peer‑reviewed pregnancy-specific data located in the provided sources.
- Is isopropyl thioxanthone safe while breastfeeding?
- No authoritative data (harmonised CLP, SCCS, CIR or peer‑reviewed studies) showing reproductive or lactation/breastmilk transfer hazards. Self‑notifications in ECHA/PubChem report H361 but are not harmonised and do not constitute definitive evidence of hazard.
- Is isopropyl thioxanthone safe for baby skin?
- No infant‑specific toxicity or mechanism data identified. Dermal exposure for infants is assigned higher exposure (e=1) relative to adults because no reliable dermal absorption data were found and infants have an immature skin barrier and higher surface‑area‑to‑weight ratio. No evidence located showing confirmed developmental/infant toxicity.
