VeriMomIs triethylene glycol safe during pregnancy?
No harmonised CLP reproductive classification was found for triethylene glycol (ECHA substance/SDS indicate no GHS reproductive classification) and CIR listings for related glycols support ‘safe as used’ assessments; peer‑reviewed human data show only very low/trace systemic detection in children exposed orally to PEG formulations (TEG detected below quantitation in a pilot study), suggesting low but measurable systemic exposure is possible but no reproductive effects were reported. Sources: ECHA registration/SDS (no harmonised CLP), CIR ingredient page, PubMed detection study.

- Is triethylene glycol safe while breastfeeding?
- Same rationale as pregnancy: no CLP/SCCS/CIR reproductive or lactation hazard identified and no mechanistic endocrine evidence. Low but measurable systemic absorption has been reported in contexts of oral exposure to PEG products (analytical methods detect TEG at very low levels), so low maternal systemic exposure — and therefore low potential for transfer to breast milk — is plausible but not demonstrated.

- Is triethylene glycol safe for baby skin?
- No infant‑specific reproductive or developmental hazard was identified and no harmonised classification exists. Because triethylene glycol is a small, water‑soluble glycol with measurable (though low) systemic detection in human biomonitoring after oral exposure, dermal absorption through immature infant skin is plausibly higher than in adults; per your guidance exposure score is increased by +1 for 0–3‑year skin. No infant toxicity or developmental effects were reported in the sources found.
