For babies 6-12 months old, this fragrance ingredient is generally considered low risk in safety reviews, but baby skin is sensitive. There is some limited evidence of mild irritation and a small signal for weak hormone effects in some studies, so care is warranted.
If you have a product with 3-Hexenol: do a small patch test on a tiny area of your baby's skin and wait 24 hours before wider use. Avoid putting the product near the eyes, mouth, or on broken or very red skin. Use it sparingly and prefer fragrance-free baby products when possible.
Watch for redness, swelling, rash, watery or irritated eyes, or any unusual behavior after product use. These concerns come from safety reviews (fragrance ingredient assessments), a national toxicology program note about weak hormone-related effects, and an agency report of possible eye irritation. If you see irritation or other worrying signs, stop use and talk to your pediatrician.
