Frequently asked questions

Is sodium sulfite safe during pregnancy?
No evidence of reproductive or developmental toxicity for sodium sulfite in major safety sources; there is no harmonised reproductive classification (no H360/H361 in Annex VI). PubChem lists acute and irritant GHS notifications (H302, H314, etc.) but these are aggregated/self-notifications and are not reproductive flags. Therefore pregnancy hazard and mechanism are scored 0 and exposure from normal topical cosmetic use is judged negligible (sources: ECHA Annex VI, PubChem GHS, CosIng).
Is sodium sulfite safe while breastfeeding?
By the same rationale as for pregnancy, there is no reproductive/lactation-specific toxicology or harmonised classification indicating risk. Dermal cosmetic use is unlikely to produce systemic levels that would meaningfully transfer into breastmilk (sources: ECHA Annex VI, PubChem GHS, CosIng).
Is sodium sulfite safe for baby skin?
No evidence of direct developmental toxicity in authoritative sources. Sodium sulfite is a small ionic, highly water-soluble compound with low likelihood of significant dermal systemic absorption in adults, so adult exposure is scored 0. However, infant skin has higher permeability and surface-area-to-weight ratio; in the absence of infant-specific dermal absorption data, exposure for 0–3 yr is conservatively increased by +1 to reflect potentially higher per‑kg uptake, while hazard/mechanism remain 0 (sources: ECHA Annex VI, PubChem GHS, CosIng).
How does VeriMom score sodium sulfite?
VeriMom scores sodium sulfite at 100/100 (no known risks) based on EU CosIng status, ECHA hazard classifications, and peer-reviewed PubMed studies. Our scoring pipeline is fully transparent.
