For children aged 5 years and older (kids, school-age children, young children), potassium aspartate used on the skin is generally safe. There are low-level notes about cancer, allergy, and reproductive concerns, so those are not a big worry for this age when products are used as directed.
Use products made for children or that clearly state safe topical use. Before full use, do a small patch test on the inner forearm and wait 24 hours to check for a reaction. Don’t put the product on cuts, scrapes, or sore skin. If you see redness, bumps, swelling, or your child says it stings, stop use and talk to your pediatrician.
The ingredient listing flags this ingredient as ‘restricted’ for some verified product programs unless the maker provides safety data, and it references the Cosmetic Ingredient Review for recommended limits—so prefer products from reputable brands that list concentrations and child-safe labeling. Avoid products that don’t list ingredients clearly, and watch for signs of skin irritation (redness, swelling, itch). If your child has a known skin allergy or very sensitive skin, check with your pediatrician before use. The restriction and CIR recommendation come from the ingredient listing and cosmetic safety review information reviewed for this assessment.
