ℹ️General Overview

This ingredient is generally low risk for babies 6–12 months old. It’s a large molecule used in creams and wipes that usually won’t get into the body. The main issue seen is mild skin or eye irritation in some people.

What to Do

Before using a new product on your baby (infant, 6–12 months), try a small patch: put a little on the inside of the forearm or thigh and wait 24 hours. Use it only on unbroken skin, avoid the eyes and face on very young babies, and choose products labeled for sensitive baby skin. If your baby has eczema or very reactive skin, check with your pediatrician first.

⚠️Warnings

Watch for redness, stinging, swelling, or rash after use. The European Chemicals Agency notes limited evidence of skin and eye irritation, and Environment Canada evaluated it as not expected to be systemically harmful. Also be aware that some product verification programs restrict this ingredient unless manufacturers supply safety data — if you see such restrictions, consider choosing a product without it if you prefer extra caution.
