For infants and newborns (0–6 months) pentylene glycol is usually low risk but requires extra care because baby skin is thinner and absorbs more. Most of the time it is safe in small amounts in products, but it can sometimes irritate or very rarely cause an allergic reaction.
Use products made for babies and those with short ingredient lists. Avoid putting new products that contain pentylene glycol on your baby’s face, near the eyes, or on broken or red skin. Don’t apply it under tight coverings (for example inside the diaper area if the product isn’t meant for diapers). If you must use a product with this ingredient, choose one labeled for infants or use it sparingly on a small area first. If redness, swelling, rash, watery eyes, or unusual fussiness develops, stop use and talk to your pediatrician.
There is evidence from safety reviews that pentylene glycol can increase how much other substances get through the skin (Cosmetic Ingredient Review) and there are animal reports of eye irritation and limited human case reports of allergic reactions (Cosmetic Ingredient Review; European Chemicals Agency). Because of that, avoid eye contact, avoid use on broken skin, and stop use if your baby shows signs of irritation.
