Potassium phosphate is usually safe in the very small amounts used in skin products. For infants and newborns it is low risk, but baby skin is extra sensitive so we stay cautious.
Choose products made for babies, use only a small amount, avoid putting it on broken skin or right next to baby’s eyes and mouth. Try a short patch: put a tiny amount on a small area of their arm and watch for 24–48 hours. If you see any rash, redness, swelling, or your baby seems uncomfortable, stop using it and talk to your pediatrician.
Regulatory reviewers (Cosmetic Ingredient Review) mention possible skin/eye/lung irritation — watch for redness, rash, swelling, or breathing changes and stop use if these appear. Environment Canada and the U.S. FDA consider it not likely to be toxic and acceptable for limited uses, but always check the whole product label: other ingredients could be more of a concern.
