Polybutene is a sticky thickener used on the skin. For toddlers (1–2 years), it is usually low risk, but there are some concerns about irritation and possible organ effects from regulatory reviews. Overall it’s not a common cause of serious harm, but treat it with care on young children’s skin.
If a product for your toddler lists polybutene: 1) Prefer products made for children or babies where the maker gives safety or concentration information. 2) Do a small patch test on your child’s inner forearm and wait 24 hours before wider use. 3) Do not apply to broken, inflamed, or sensitive areas. 4) Avoid frequent or all-over use and avoid use in the diaper area where skin is covered and moisture is trapped. 5) Stop use and talk to your pediatrician if you see redness, rash, swelling, or any new symptoms.
Some government agencies (Environment Canada and the European Chemicals Agency) have raised concerns about possible non-reproductive organ effects and have noted evidence of irritation. An industry safety review (Cosmetic Ingredient Review) also notes data gaps and limits on how it should be used. Because of those findings, avoid heavy or prolonged use on toddlers, avoid use on damaged skin, and look for products where the manufacturer provides safety or concentration information.
