ℹ️General Overview

For babies 6-12 months (infants, babies), this ingredient is a caution. It is an antimicrobial that some health authorities limit or restrict. It is not commonly used in baby skin products and may cause irritation or other problems, and experts have asked for limits or more data.

What to Do

Avoid products with this ingredient for routine baby skin care. If you find a product that lists it and you think you must use it, do not use it on broken skin, choose a rinse-off product at low concentration if possible, do a small patch test on a tiny area and wait 48 hours, and check with your pediatrician before using. Keep any product containing this ingredient away from your baby’s mouth and eyes and out of reach.

⚠️Warnings

Do not use this ingredient on infants if the product is intended to stay on the skin until a doctor or trusted safety statement recommends it. Regulatory bodies (Health Canada and safety review panels) have limited or recommended limits for its use in cosmetics, and the European Chemicals Agency has flagged possible reproductive or developmental concerns. The U.S. food safety authority prohibits it in food, and some reviewers note that safety is unknown for leave-on skin products. Watch for redness, swelling, rash, or any change in feeding or behavior — stop use and call your pediatrician if those occur.
