6-12 month old babies • Skin contact product
For babies 6–12 months old, polyisobutene is generally low risk when it’s used in small amounts in products made for babies. It’s a common ingredient that helps products feel smooth and stay on the skin.
Use products that are specifically made and labeled for babies. Try a small patch test on a clean area (inside forearm or thigh) and wait 24 hours before wider use. Keep creams away from the eyes and mouth, and use only a small amount. If your baby drools or puts hands in their mouth after application, gently wipe their mouth and hands.
Stop use and talk to your pediatrician if you see redness, swelling, a rash, or eye irritation. Some government safety reviews have noted limited evidence of irritation and some flagged possible organ-system concerns in certain assessments (sources: Environment Canada, European Chemicals Agency); these are rare but worth watching for. Also note that the FDA and industry reviews note safe, limited uses—if a product isn’t made for babies or lists unusually high concentrations or unclear ingredients, avoid it.
