For children aged 2–5 years (toddlers, preschoolers, young children), calcium phosphate used on the skin in normal products is generally safe. Health and regulatory reviews (U.S. Food and Drug Administration; Environment Canada; Cosmetic Ingredient Review) show low concern for serious harms. The main possible issue is mild irritation to the skin, eyes, or breathing if dust or powder is inhaled or the product gets into the eyes or nose.
Use products that list this ingredient following the product directions. Avoid powdered forms that the child could breathe in. Before regular use, do a small patch test on the inside of the forearm. Apply products with adult supervision, keep them away from the child’s eyes and mouth, and rinse thoroughly if they get in eyes. If you see redness, rash, swelling, or your child coughs or has trouble breathing after exposure, stop use and contact your child’s healthcare provider.
Watch for skin redness, stinging, or eye irritation — this possible irritation is noted by the Cosmetic Ingredient Review (CIR). Avoid inhaling powders (inhalation can irritate the lungs; FDA notes safe uses in food but dust can be a breathing irritant). Environment Canada classifies the ingredient as low human health priority and not likely to build up in the body, but if your child has very sensitive skin or a known allergy, avoid use and check with your pediatrician.
