For toddlers and preschoolers (ages 2-5), this ingredient can irritate skin and can cause allergic reactions in some people. There is also a manufacturing contamination concern (nitrosamines). Overall, it’s a moderate concern for this age group.
Prefer products made for children that do not list triethanolamine. If a product does contain it, choose rinse-off items (like some shampoos or washes) rather than leave-on creams or lotions, and use them sparingly. Do a small patch test on your child’s forearm and wait 24 hours before wider use. Stop use and check with your child’s pediatrician if you see redness, rash, swelling, or other changes.
Watch for skin redness, persistent itching, hives, or swelling—these signs suggest an allergic reaction (sources: Cosmetic Ingredient Review and occupational health reviews). Avoid products that are leave-on for young children because regulators place limits on concentration and use in leave-on products (source: Cosmetic Ingredient Review). There is also a contamination risk from nitrosamines during manufacturing—try to buy from reputable brands and avoid products with unclear labeling or from unknown sources (contamination concern noted by regulatory reviews). If your child has breathing problems or sudden severe reactions, seek emergency care (occupational health reports note respiratory sensitization in some exposed adults).
