For children 5 years and older (kids, school-age children, tweens and teens), calcium silicate used on the skin is considered very low risk. It’s an inactive mineral added to keep products dry and stable.
Use products that include this ingredient only as directed. Avoid dusty or loose powder products where a child could breathe in the powder. Do a small patch test on a forearm first if your child has sensitive skin. Do not put products on broken, raw, or very irritated skin. If your child gets a rash, redness, or swelling, stop use and rinse the area, and see a doctor if it doesn’t get better.
The main safety notes come from government and industry reviews: some agencies list it as low concern for health effects (Environment Canada), while industry safety reviewers point out limits on concentrations and some gaps in data (Cosmetic Ingredient Review / industry safety panel). The U.S. Food and Drug Administration has regulatory notes about allowed or prohibited uses in foods, so manufacturers may limit how it’s used in products. Watch for inhalation risk from powders and for products that do not list safety or concentration information—if in doubt, choose a different product.
