For 6–12 month old babies (infants), triethanolamine can irritate skin and sometimes causes allergic reactions. It is more commonly a concern for products that stay on the skin (like lotions) than for products that are washed off.
1) Prefer baby products that do not list triethanolamine on the label. 2) If you must use a product with triethanolamine, choose a rinse-off product (baby wash or shampoo) rather than a leave-on lotion. 3) Do a small patch test on a tiny area of baby’s skin and wait 24–48 hours before regular use. 4) Avoid putting it on broken or inflamed skin (eczema). 5) If you see redness, rash, swelling, or breathing changes, stop use and contact your pediatrician.
Main things to watch for: skin redness, rash, swelling, itching or new worsening of eczema, and any breathing trouble. Concerns come from safety reviews that report skin and respiratory allergen effects and from notes about possible contamination by nitrosamines. Experts also recommend limits on how much can be used and prefer rinse-off over leave-on products. If your product is a leave-on cream that lists triethanolamine, consider switching to a product made for infants without this ingredient.
