For infants and newborns (0–6 months): overall low concern from available safety reviews, but topical use on babies is not well studied. Because baby skin is delicate, we recommend avoiding unnecessary products that contain this sweetener.
If you find a baby product that lists acesulfame potassium, prefer products made and labelled for infants. Do not apply it to broken or sore skin, and avoid putting it near your baby's mouth or eyes. For a new product, try a very small amount on a tiny patch of the baby's forearm and watch for 24 hours. Stop use and call your pediatrician if you see redness, swelling, blisters, or if your baby becomes unusually fussy or has trouble breathing.
Sources such as the U.S. food safety agency and Canadian assessments list this ingredient as acceptable for limited use in foods and not expected to be organ-toxic, persistent, or to build up in the body. Still, topical safety data in newborns is limited. Watch for skin rash, swelling, hives, or breathing problems — these are signs of an allergic reaction and need immediate medical attention. Avoid using products with this ingredient on infants if they are not specifically formulated for babies, and avoid application to large areas of skin.
