For newborns and babies 0–6 months: this fragrance ingredient is generally considered low risk in adults, but there is limited government evidence of weak hormone effects and some developmental concerns. Because babies are more sensitive, it’s safer to avoid putting products with this fragrance directly on an infant’s skin.
Choose fragrance-free baby products for newborns and infants. If a product lists Gamma Undecalactone, avoid applying it to your baby’s face, neck, or broken skin. If you must use a product with a fragrance, try it on a small patch of baby’s skin (for older infants), use it sparingly, and stop if there is any redness, rash, or irritation.
Watch for redness, rash, fussiness after application, or any breathing difficulty — stop use and seek help if these occur. These cautions come from government toxicology findings (National Toxicology Program) that showed weak endocrine activity and limited evidence of developmental toxicity in some studies; other agencies note low overall hazard and limited persistence. Because this information includes government reports, we recommend extra caution with infants.
