1-2 year old toddlers • Skin contact product
For toddlers (1–2 years): this preservative has some safety limits from regulators and only limited data for little children. It is not the safest choice for daily leave-on products for toddlers.
If you can, choose products for toddlers that do not list PHMB, polyhexanide, polyaminopropyl biguanide or the other synonyms. If a product with this ingredient is needed, prefer rinse-off products (like some shampoos or washes) over leave-on lotions. Do a small patch test on a small area of the child’s skin and wait 24 hours before wider use. Avoid using on broken or irritated skin and keep away from eyes and mouth.
Safety reviews and regulatory guidance have placed restrictions or bans on some uses and concentrations (see sources such as Cosmetic Ingredient Review, EU cosmetics rules, Japan Ministry of Health and specific safety opinions). These reviews are the reason for concern. Watch for redness, rash, swelling, eye irritation, coughing or breathing changes after use — stop use and contact your pediatrician if these appear. Because data in young children are limited, many experts recommend avoiding this ingredient in products intended for toddlers when safer alternatives exist.
