Quick Answer: Isononyl Isononanoate is generally considered safe for 0-6 month old babies when used in topical products. Always consult your pediatrician for newborns.

ℹ️General Overview

For infants (0–6 months): this ingredient is generally low risk and is used to make skin feel soft. However, there’s limited testing done specifically in newborns, and industry safety reviews recommend limits on how it’s used in products. Because babies’ skin is very delicate, we should be careful.

What to Do

When caring for a newborn or baby under 6 months, choose products made for infants, use as little as needed, and avoid applying to large areas repeatedly. Avoid products with many unfamiliar additives. If you must try a new product, try a small amount on a tiny patch of skin away from the face first (for older babies) and wait 24–48 hours to see if there’s any reaction. If you have any doubt, ask your pediatrician.

⚠️Warnings

Watch for redness, rash, swelling, itchy skin, or any breathing problems after using a product — stop use and seek medical help for severe reactions. Do not apply to broken, raw, or irritated skin. Follow product instructions and prefer formulations made for infants because industry safety reviews note limits on concentration and impurities (Cosmetic Ingredient Review). If a product lists unusually high concentrations or isn’t intended for babies, don’t use it on infants.
