FAQ

Is boric acid safe during pregnancy?

Boric acid (CAS 10043-35-3) carries a harmonised CLP classification Repr.1B H360FD (may damage fertility; may damage the unborn child) in EU Annex VI, which supports a confirmed high reproductive hazard. Animal and regulatory reviews report developmental toxicity (reduced fetal weight, malformations) after systemic (oral) exposure and conclude a developmental NOAEL; mechanistic/toxicokinetic data show maternal–fetal transfer of boron, supporting demonstrated mechanism. See EU Official Journal Delegated Regulation 2023/1435 (Annex VI), ECHA substance information and SR/reviews (CIR; peer-reviewed reviews).

Is boric acid safe while breastfeeding?

Harmonised classification (H360FD) and evidence that boron crosses placenta and is present in human milk support reproductive/developmental concern during lactation; studies and assessments report detectable boron in breast milk and mother–infant transfer, so systemic maternal exposure could expose nursing infants. Risk via cosmetic topical use is expected to be low but measurable if significant systemic absorption occurs. See ECHA/Delegated Regulation and human milk/assessment reports.

Is boric acid safe for baby skin?

Hazard is driven by the harmonised H360 classification of boric acid (Repr.1B); infant-specific hazard evidence was not identified to change h or m, but immature infant skin raises exposure potential — dermal exposure preparedness is higher for 0–3 y (so exposure score increased by +1). Topical cosmetic use has low dermal absorption in adults but infants have higher surface-area-to-weight and immature barrier, so exposure is greater. See EU classification, SCCS/CIR reviews and human milk/placental transfer data.

How does VeriMom score boric acid?

VeriMom scores boric acid at 20/100 (high risk) based on EU CosIng status, ECHA hazard classifications, and peer-reviewed PubMed studies. Our scoring pipeline is fully transparent.
