Is this kid-friendly to use Polyquaternium 37?
ℹ️General Overview
For kids 5 years and older, this ingredient is generally safe in everyday hair and body products, especially when it’s in rinsed-off products like shampoos and washes.
✅What to Do
Choose products made for children or rinse-off cleaners when possible (shampoo, body wash). If using a leave-on product (lotion, cream), pick one labeled for kids or for sensitive skin. Do a small patch test on the inside of the forearm and check the area for 24–48 hours before regular use. If you see redness, rash, swelling, or fussiness, stop use and talk to your child’s provider.
⚠️Warnings
Two safety review sources note specific things to watch for: the Cosmetic Ingredient Review says safe use can depend on concentration and whether a product is leave-on or rinse-off, so avoid unknown leave-on formulations for young children; Environment Canada has raised limited concerns about environmental toxicity and possible organ effects in some studies — this is not proof of harm at normal product levels but is a reason to be cautious. Avoid using on broken skin, keep the product out of eyes and mouth, and stop use and seek care if you notice signs of an allergic reaction. If a large amount is swallowed or there is a concerning reaction, get medical help right away.
