For newborns and infants (0–6 months) this ingredient is best avoided when possible. It’s an antiseptic that is allowed in some products but there are warnings and limits from health authorities and some animal and lab studies that suggest caution is needed for very young babies.
Do not use products that list benzethonium chloride on healthy baby skin unless your pediatrician tells you to. If a doctor prescribes a product with it, follow their instructions exactly and use only the product and dose recommended. Check product labels for alternate safer options (look for products labeled safe for newborns/infants). If you need an antiseptic for a small cut or wound, ask your child’s doctor for a baby-specific recommendation.
Avoid products with benzethonium chloride on infants’ skin, especially on broken skin, near eyes, mouth or diaper area. Health Canada and cosmetic safety reviewers place limits or restrictions on its use in some countries — that is a reason to be cautious. Animal studies have shown effects on fertility at higher exposures, and lab studies showed possible effects on nerve cells; there is also some evidence of allergic reactions. If you see any redness, swelling, rash, breathing trouble, or unusual behavior after using a product, stop use and contact your pediatrician or emergency services.
