Frequently asked questions
- Is potassium phosphate safe for baby skin?
- No evidence of developmental or infant-specific toxicity (h/m = 0). Dermal absorption of inorganic, highly water‑soluble ionic salts is generally low; however, because infant skin has higher surface-area-to-weight and an immature barrier, exposure potential is modestly higher than adults (exposure score increased to 1). No infant-specific adverse data were found.
