For infants (0–6 months) this ingredient is a fragrance that is generally low risk in adults, but babies have very sensitive, thin skin. There is a small, low-level signal for hormonal activity in one review, so extra care is recommended for newborns and young babies.
Prefer fragrance-free products for newborns and babies. If a product containing this ingredient must be used, avoid applying it to baby’s face, hands that go in their mouth, or any broken or red skin. Use it very rarely, in small amounts, and wash it off if you see any redness or fussiness. If you are unsure, choose a fragrance-free baby product instead.
Watch for redness, rash, swelling, blisters, or breathing changes after use and stop using the product immediately if any of these occur. The warning about possible weak hormonal activity comes from a National Toxicology Program review; other agencies note it is allowed in limited food use (FDA) and not expected to be toxic (Environment Canada). Because babies absorb more through their skin, avoid regular or widespread use on infants under 6 months.
