Frequently asked questions
- 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).
- Is sodium sulfite safe for newborns?
- 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).
