For newborns and babies under 6 months, tromethamine is treated cautiously. Official reviews say it is unlikely to cause cancer or long-term harm, but regulators have placed limits on how it can be used in cosmetics. Baby skin is delicate and absorbs more, so extra care is needed.
Only use products that are specifically labeled for babies or that your pediatrician recommends. Avoid applying products containing tromethamine to broken, red, or inflamed skin. If you must use a product with tromethamine, use a small amount on a small area once and watch for any redness or irritation before using more. Prefer products formulated for infants and designed to minimize extra ingredients.
Regulatory sources (for example, the EU Cosmetics Directive and industry safety reviewers) list use or concentration restrictions for this ingredient — that is the primary concern. Environment Canada reviews indicate it is not expected to be toxic or to build up in the body. Still, because infant skin is thin and more absorbent, watch for redness, swelling, rash, or fussiness after application and stop use and contact your pediatrician if these occur.
