Frequently asked questions

Is potassium nitrate safe for baby skin?

No infant-specific toxicology demonstrating greater hazard was found, so hazard and mechanism remain as for adults (h=2, m=2). However, infant skin has higher surface-area-to-weight and an immature barrier, and while potassium nitrate is an inorganic, water‑soluble salt with low dermal penetration, the baby exposure score is increased by +1 relative to adults to reflect greater per‑kg exposure potential from topical application (e=1).

Is potassium nitrate safe for newborns?
