ℹ️General Overview

For children age 5 and up (school‑age kids and older), this ingredient is generally low risk when used in normal skin products. The main issues reported are mild irritation and the fact that it can make other ingredients get into the skin more easily.

What to Do

If you plan to use a product with this ingredient on a child: choose products made or labeled for children when possible; do a small patch test on the inner forearm and wait 24 hours; avoid using on broken, red, or sore skin; don’t combine with strong active ingredients (like high‑strength acids or prescription retinoids) on kids; stop use and rinse if you see redness, burning, or swelling; and talk to your child’s pediatrician if you’re unsure or if a reaction is worse than mild.

⚠️Warnings

Limited evidence shows this ingredient can irritate skin, eyes, or the airways and it is listed as a penetration enhancer by safety reviewers (Cosmetic Ingredient Review, European Chemicals Agency, and a 2017 toxicology/ecotoxicology study). Some product verification programs restrict its use unless manufacturers provide extra safety information — for extra caution, avoid products that combine it with strong actives on children and watch for any signs of irritation.

Safety Risk Labels

This ingredient has the following documented risks:

Irritant: There is limited evidence that this chemical can irritate skin, eyes, or lungs when used on skin. European chemical regulators and a toxicology review report cases of mild skin and eye irritation and possible respiratory irritation, so babies with very sensitive skin could get redness, itching, or breathing discomfort.
Absorbed: A cosmetic safety review identifies this ingredient as a penetration enhancer. That means it can help itself and other ingredients get through the skin and into the body more easily. Because it can boost skin uptake, there is a higher chance that more of a product’s ingredients will enter a child’s body unless limits are set.
