For infants (0–6 months): treat this ingredient with caution. While general health hazards are reportedly low, there are worries about contamination by chemicals that can form during manufacture and some potential to irritate delicate skin or eyes. Newborn skin is more absorbent and sensitive, so limit exposure.
If possible, choose products formulated for newborns that do not list Trideceth-12. Avoid leave-on products (creams, oils) containing it on babies under 6 months; if the ingredient is in a rinse-off product (bath or shampoo), use sparingly and rinse thoroughly. Do not apply to broken or very red skin. If you must use a product with this ingredient, test a very small area first and watch for redness, swelling, fussiness, or breathing changes. When in doubt, ask your pediatrician.
Watch for skin redness, rash, stinging, eye irritation, or any breathing changes after use. There are documented concerns about contamination with ethylene oxide and 1,4‑dioxane (manufacturing byproducts) and some regulatory reviews note potential irritation and non-reproductive organ toxicity (sources: Environment Canada; Cosmetic Ingredient Review). Also note that some product certification programs restrict use of this ingredient unless manufacturers can show it is safe for their standards.
