For newborns and infants (0–6 months) this ingredient is best avoided if you can. It can irritate sensitive baby skin and has a known risk of causing allergic reactions in some people. There is also a contamination concern (nitrosamines) during manufacturing.
Try to choose products made specifically for babies and labeled for newborn use. If a product contains triethanolamine, prefer rinse-off products (like shampoos) over leave-on creams for infants. Use as little product as needed, avoid applying it to broken or very red skin, and stop use if you see redness, rash, swelling, or irritation.
Look out for skin redness, rash, itching, or swelling after using a product with this ingredient — strong evidence of skin allergy and irritation comes from the Cosmetic Ingredient Review and the Association of Occupational and Environmental Clinics (AOEC). Manufacturers and regulators have set limits on how and how much triethanolamine can be used (Cosmetic Ingredient Review; EU rules). Also be aware of contamination risks with nitrosamines during manufacture — nitrosamines are a contamination concern flagged by safety reviews. If you suspect a reaction, wash the area with water and call your pediatrician.
