ℹ️General Overview

For babies aged 6-12 months (infants), this ingredient is usually low risk when used in small amounts on normal, unbroken skin. The main concern found in studies is irritation only at high levels in animals.

What to Do

If you use a product that contains this ingredient on your baby: pick products made for babies, do a small patch test on a small area first, avoid putting it on broken or very red skin, do not use spray forms near the face or where your baby can breathe it in, and stop use and rinse with water if you see redness, rash, or eye irritation. If a reaction continues or is severe, contact your pediatrician.

⚠️Warnings

Animal studies reviewed by the Cosmetic Ingredient Review (CIR) reported skin irritation only at high doses—this is the source of the irritation warning. Also, some product verification programs limit use of this ingredient unless makers provide safety data, so prefer baby-specific, reputable brands. Avoid sprays (risk of breathing it in) and avoid use on broken skin. Watch for new rash, persistent redness, or eye problems and stop use if these occur.
