For toddlers and preschoolers (2–5 years old), polyethylene is usually low risk. It’s a plastic used to make films or tiny solid particles. It’s not linked to cancer or long‑term harm, but it can irritate skin, eyes, or breathing in some people.
Use products with polyethylene only as directed. Prefer products that are not dusty or powdery (avoid inhalation). Don’t put products on broken or chapped skin. If trying a new product, test a small patch on your child’s arm first and wait 24 hours. Rinse well if it gets in the eyes. Keep products out of reach so children don’t put them in their mouth.
Watch for redness, stinging, rash, eye watering, or coughing after use—these are signs of irritation (reported by cosmetic safety reviewers). Avoid powdered or abrasive forms around young children because breathing in small particles can irritate the lungs (Cosmetic Ingredient Review). Regulators note some data gaps and recommend limiting concentrations and avoiding use where product may be inhaled or used on damaged skin (Cosmetic Ingredient Review; FDA; Environment Canada).
