ℹ️General Overview

For infants (6–12 months), this fragrance ingredient is likely low risk in the tiny amounts used to scent products, but there is some limited evidence from government studies of possible developmental or mild hormone-related effects. Because babies are more sensitive, we keep exposure low.

What to Do

Prefer fragrance-free baby products when possible. If a product does contain this ingredient, use only a small amount, avoid applying it to large areas of baby’s skin or to broken skin, keep it away from the face and mouth, and do not use multiple fragranced products in the same routine. Do a small patch check on the inner forearm and wait 24 hours before wider use. Stop use and wash the area if you see redness, rash, swelling, or any breathing change, and check with your pediatrician if you are unsure.

⚠️Warnings

Watch for skin redness, rash, hives, swelling, or breathing changes — these are signs of irritation or allergy and should prompt stopping the product. Some government toxicology reports note limited evidence of developmental effects and weak hormone-related activity (reported by the National Toxicology Program), so avoid routine whole-body or frequent use on babies. Other agencies note it is allowed for limited uses (FDA) and not expected to be highly toxic or persistent in the environment (Environment Canada, European Chemicals Agency).

Safety Risk Labels

This ingredient has the following documented risks:

Hormones: A U.S. toxicology review found studies showing weak endocrine effects. That means this ingredient can act on the body’s hormone systems, which could affect a child’s normal hormone development.
Confuse Hormones: The same U.S. toxicology source reports evidence of endocrine activity. This suggests the ingredient can mimic or change hormone signals, which may confuse a child’s growing hormone system.
Brain Development: The U.S. toxicology review also notes limited evidence of developmental harm. Limited evidence of developmental toxicity can include effects on early growth or brain development in young children.
Fertility: There is limited evidence of developmental and reproductive harm reported by the U.S. toxicology review. That raises a possible small risk to future reproductive health.
Environmental: A European chemicals agency reported limited evidence of environmental toxicity. That means this chemical may pose some, though small, risk to wildlife or habitats if released into the environment.
