0-6 month old newborns • Skin contact product
For newborns and infants 0–6 months, this fragrance ingredient is not shown to be highly dangerous, but babies are more sensitive than adults. It may irritate eyes or very sensitive skin, and there are some older animal and laboratory signals (small or weak) about hormone effects and kidney effects at very high doses.
For babies and newborns, choose products labeled fragrance-free whenever possible. Do not apply products with strong scents directly to an infant’s skin, and avoid putting scented products near your baby’s face or eyes. If a product that may contain this ingredient is used on your baby, watch for redness, rash, fussiness, breathing changes, or eye irritation and stop use right away.
What to watch for and avoid: 1) Eye or skin irritation — some data show limited eye irritation (European Chemicals Agency). 2) Weak hormone-related signals reported in reviews (National Toxicology Program noted weak endocrine activity). 3) Animal studies reported kidney effects only at high doses (older toxicity studies). 4) While a fragrance safety review found it unlikely to be allergenic in people, infants can react differently — if you see any redness, swelling, rash, or breathing problems stop use and contact your pediatrician. If you want to remove doubt, use fragrance-free baby products and avoid intentional topical use on infants under 6 months.
