For infants (0–6 months): this ingredient is generally considered low risk in safety reviews, but there is limited testing in newborns. Babies have very sensitive, thin skin, so extra caution is advised.
If you use a product that lists undecylenoyl glycine on a baby’s skin, choose formulations made for infants and use a small amount on a small area first. Keep products away from the eyes and mouth. Do not use on broken, red, or inflamed skin. If you see any rash, redness, swelling, or fussiness after use, stop immediately and talk to your pediatrician.
Watch for skin irritation or eye irritation — expert reviews (Cosmetic Ingredient Review and the European Chemicals Agency) note possible mild irritation in some people. Also be aware that some product-verification programs restrict this ingredient unless makers provide extra safety data; that means manufacturers may need to show proof it’s safe in baby products. If you’re unsure, avoid using it on newborns and consult your child’s doctor.
