Triisostearin is a softening oil used on the skin. For infants (newborns and babies 0–6 months) the overall concerns are low, but because baby skin is very thin and the ingredient can help other substances get through the skin, we should be cautious.
If you choose a product that contains triisostearin for your baby: 1) Prefer products that are specifically formulated for infants or labelled for newborn use. 2) Use sparingly and only where needed. 3) Do a small patch test first (apply a tiny amount to a small area of the baby's forearm or thigh and wait 24 hours). 4) Never put it on broken, raw, or irritated skin. 5) Stop use and talk to your pediatrician if you see persistent redness, rash, swelling, or other concerns.
Expert safety reviews note two things to watch for: (1) triisostearin can act as a penetration enhancer — it may increase how easily other ingredients pass through the skin (source: Cosmetic Ingredient Review), and (2) there are data gaps and recommended limits on concentration — industry safety panels say more information is needed about safe concentrations in products. Also, some product-certification programs restrict this ingredient unless manufacturers provide safety data. Avoid regular or large-area use on infants, avoid use on broken skin, and seek medical advice for any concerning reaction. For severe reactions (trouble breathing, swelling of face or lips), get emergency care right away.
