For newborns and babies 0-6 months: this ingredient is generally seen as low risk in safety reviews, but there is limited data and some product programs limit its use. Because baby skin is very sensitive, use extra caution.
If possible, choose baby-specific products without this ingredient for infants under 6 months. If a product with polyquaternium-11 is needed, use a tiny amount, keep it away from the face, mouth and eyes, and avoid applying to irritated or broken skin. Watch baby’s skin for any redness, rash, or unusual fussiness after use and stop use if any appear.
Avoid products with this ingredient on babies under 6 months unless the product is clearly made for infants. The caution comes from industry safety reviews and regulatory assessments (Cosmetic Ingredient Review and Environment Canada) that note low concern but also point out data gaps and limits on safe concentrations. If you see redness, swelling, blisters, or if the baby seems uncomfortable, stop use and call your pediatrician.
