For newborns and infants (0-6 months) polyethylene is usually low-risk for long-term illness, but it can irritate sensitive baby skin, eyes, or breathing. Reviews also note limited safety data and assume the ingredient is not absorbed much into the body.
If you see polyethylene on a baby product label: prefer items made and labeled for infants/newborns. Do not use products with this ingredient on broken, red, or sore skin. If you decide to try a product with polyethylene, test a small area (behind the knee or inner arm) first and wait 24 hours. Stop use right away if you see redness, rash, swelling, or any breathing changes. For everyday care of newborns and babies, choose products made for babies and fragrance-free when possible.
Be careful because safety reviewers have found clear evidence of irritation risk and have noted gaps in safety data (Cosmetic Ingredient Review). Other authorities say it is not likely to cause cancer and is not expected to build up in the body (IARC, Environment Canada). Some product-verification programs require additional proof before allowing this ingredient. Stop use and talk to your pediatrician if you notice rash, persistent redness, eye irritation, or any breathing trouble.
