For children aged 5 years and older (school-age kids), potassium phosphate used on the skin is generally low risk. Safety authorities have reviewed it and do not list major long-term dangers, but some people can get irritation.
Use products that contain potassium phosphate exactly as the product label says. Before full use, do a small patch test on a child’s inner forearm and wait 24 hours to check for redness or itching. Don’t apply on cuts, scrapes, or irritated skin. Keep products away from eyes and mouth. If any redness, stinging, swelling, or breathing difficulty appears, stop use and rinse the area; seek medical help if severe.
Although major long-term risks are rated low, an expert review flags possible skin, eye, or lung irritation (Cosmetic Ingredient Review). Regulatory sources note it is allowed for limited use in food (FDA) and is not expected to accumulate in the body (Environment Canada). Watch for skin reactions, eye irritation, or breathing issues and stop use if these occur.
