ℹ️General Overview

For kids 5 years and older (school-age children), this ingredient is generally safe in skin products. Most safety reviews find little or no long-term health worry. The main thing to watch for is mild irritation, not more serious problems.

What to Do

If you plan to use a product with this ingredient on a child 5+ years old: do a small patch test first (apply a tiny amount to the inside of the forearm and wait 24 hours), avoid using on broken or very irritated skin, keep powder forms away from the nose and mouth to prevent breathing in dust, and follow product directions. If your child has eczema or very sensitive skin, talk to your pediatrician before use.

⚠️Warnings

Watch for signs of irritation such as redness, itching, swelling, or coughing. Reports note possible skin, eye or lung irritation (Cosmetic Ingredient Review). Regulatory notes show the ingredient is generally low concern for health effects (Environment Canada) and has specific limited uses or restrictions noted by the U.S. Food and Drug Administration — so some regulatory context applies depending on the product. If you see any irritation or breathing trouble, stop use and contact your child’s healthcare provider.
