FAQ
- Is trimethylhexanol safe during pregnancy?
- No harmonised ECHA Annex VI classification (H360/H361) was found; available H361 labels appear on supplier SDS/product listings and not as an EU-harmonised C&L entry. REACH/ECHA contains a registration dossier for 3,5,5-trimethylhexan-1-ol (CAS 3452-97-9) but I found no SCCS or CIR reproductive safety assessment nor peer‑reviewed studies demonstrating reproductive toxicity. Given limited evidence of systemic reproductive hazard, hazard (h)=0. Dermal exposure from cosmetic use is plausible but low-to-measurable for a C9 primary alcohol (e=1). Sources: ECHA substance/registration pages, PubChem, supplier SDSs/C&L listings.
- Is trimethylhexanol safe while breastfeeding?
- No data showing effects in lactation or transfer via milk; no mechanistic data for reproductive or endocrine activity found. As for pregnancy, hazard and mechanism scores default to 0. Low but measurable dermal absorption expected in typical cosmetic use (e=1).
- Is trimethylhexanol safe for baby skin?
- No infant-specific toxicology identified. Per your rules, when an ingredient has measurable dermal absorption in adults increase exposure score by +1 for infants — adult e=1 → baby e=2. No evidence to raise hazard or mechanism scores for infants.
- How does VeriMom score trimethylhexanol?
- VeriMom scores trimethylhexanol at 33/100 (high risk) based on EU CosIng status, ECHA hazard classifications, and peer-reviewed PubMed studies. Our scoring pipeline is fully transparent.
