For babies aged 6–12 months (older infants), tromethamine is generally considered low risk when used in small amounts in finished products. Still, there are official use limits and not many studies done just in babies, so we recommend being careful.
Choose products labeled and formulated for babies or products where the manufacturer states safe use for infants. If a product with tromethamine is needed (for example a medicated product), use as directed by your pediatrician. Before regular use, do a small patch test on a clean area of the baby's thigh or inner forearm and watch for 24–48 hours. Don’t use products with this ingredient on broken, red, or very sensitive skin, and avoid the face/eye area. If you see redness, swelling, blistering, or other changes, stop use and contact your child’s healthcare provider.
Regulatory listings (for example the EU Cosmetics Directive and notes from Cosmetic Ingredient Review) flag use restrictions on tromethamine — that is the main reason to be cautious. Although data lists low allergy and cancer concerns, infants can be more sensitive than adults. Also note Environment Canada information that the chemical is not suspected to persist or accumulate. If concentration or safety testing for infant skin is not disclosed on the product, prefer alternatives formulated for babies.
