For children 5 years and older (kids, school-age children, tweens, teens), polybutene — a common thickener or binder in creams, lotions and lip products — is usually low risk when used on normal, unbroken skin in regular cosmetic amounts.
Before widespread use, do a small patch test on the inside of the forearm and wait 24 hours. Use products meant for children when possible. Avoid applying to cuts, rashes, or sore skin. If your child gets redness, itching, swelling, or any breathing trouble after using a product, stop use and rinse the area, and contact your pediatrician.
Some government agencies have noted limited evidence of skin, eye or lung irritation (source: European Chemicals Agency) and have flagged potential non-reproductive organ-system concerns in certain assessments (sources: Environment Canada, European Chemicals Agency). Industry reviews also note data gaps and recommended concentration limits for some product types (source: Cosmetic Ingredient Review). Because of this, watch for irritation, avoid use on broken skin, keep products out of reach to prevent licking or swallowing, and prefer kid-formulated products or those with clear safety documentation.
