For infants and newborns (0–6 months), this ingredient is best avoided when possible. There is limited information for babies this young and some official reviews raise contamination and restriction concerns.
Choose products made for newborns that do not list Polyquaternium-7. If a product with it is the only option, use it only briefly (rinse-off), avoid putting it near the eyes or on broken skin, test a tiny area first, and stop use if the baby’s skin becomes red, flaky or swollen. Talk to your pediatrician before using it regularly.
There are reports from government and industry reviews about possible contamination with acrylamide and rules limiting how the ingredient can be used (for example: Environment Canada, the EU cosmetics rules, and industry safety reviews). Watch for redness, swelling, increased crying with touching a spot, or any new skin changes after using a product that contains this ingredient—if you see these, stop use and seek medical advice.
