2-5 year old preschoolers • Skin contact product
For 2-5 year olds (toddlers and preschoolers), polyisobutene is usually safe on the skin in the small amounts found in creams and lotions. It helps products feel smooth and hold moisture and rarely causes serious problems.
Use products made for children when possible. Apply a small amount first and do a patch test behind the ear or on the inner arm; wait about 24 hours to see if the child has any reaction. Do not put products containing this ingredient on broken or irritated skin. Avoid spraying near the face to prevent breathing it in. If you need to use a product over a large area or every day, choose formulas labeled for kids or talk with your child’s doctor.
Stop use and rinse if you see redness, rash, stinging, or eye irritation. Some government agencies (Environment Canada and the European Chemicals Agency) have noted possible organ-system effects at high exposures and limited irritation potential — so avoid heavy, repeated application over the whole body and avoid inhaling sprays. The U.S. Food and Drug Administration and Cosmetic Ingredient Review note allowed, limited uses; if a product contains many other active ingredients, check the full label and consult a pediatrician if you have concerns.
