This ingredient is used to kill germs but some governments limit its use and we don’t have strong safety data for leaving it on the skin. For newborns and babies under 6 months, it’s best to avoid it when possible.
Don’t put products containing 8-hydroxyquinoline on infants (newborns, babies 0-6 months) unless a pediatrician tells you to. If a doctor prescribes it, follow their instructions exactly, prefer rinse-off products or very short contact, use the smallest amount needed, and stop use if you see any irritation. Keep all products out of reach of children.
Do not use leave-on creams or lotions with this ingredient on babies because safety for leave-on use is unclear (Cosmetic Ingredient Review notes data gaps). Some countries restrict its cosmetic use (Health Canada). A European agency flagged possible developmental or reproductive concerns (ECHA), and there is limited evidence of skin reactions. Avoid applying to broken skin, diaper areas, or wide areas of a baby’s body, and tell your pediatrician if the baby is taking other medicines or has health issues.
