Frequently asked questions
- Is potassium hydroxide safe for baby skin?
- No evidence of reproductive hazard for infants, so hazard (h) and mechanism (m) remain 0. However, because KOH is a strong corrosive agent (ECHA Annex VI H314) and infant skin has an immature barrier and higher surface-area-to-weight, potential for local damage and greater percutaneous uptake is higher; therefore exposure score is raised by +1 for baby skin. Primary risk for infants is topical corrosion/irritation rather than developmental toxicity (sources: ECHA Annex VI, PubChem GHS).
