For newborns and infants (0-6 months), undecane is likely low risk when only a tiny amount is used on a small area of skin. But babies have very thin, sensitive skin and there isn’t much direct evidence for this age, so extra caution is wise.
If you see undecane listed in a product you want to use on a baby: choose products made for infants, use a very small amount on a small area first, avoid using it on the face or near the nose and mouth, do not apply to broken or irritated skin, and do not use aerosol sprays containing it. Stop use and wash the area if you see redness, swelling, or any sign of irritation.
Regulatory sources note it is not likely carcinogenic and has low allergy and reproductive concerns (U.S. EPA; Environment Canada). Environment Canada also flags possible environmental toxicity — avoid sprays that spread widely. Watch for skin irritation or allergic reaction and discontinue use if your baby shows any signs. If you’re unsure, check with your pediatrician before using a new product on a baby under 6 months.
