⚠️
USE WITH CAUTION
Danger Score: 4 (Lower is safer)
Quick Answer: Methylpropanediol use with caution for 0-6 month old babies when used in topical products. Always consult your pediatrician for newborns.

ℹ️General Overview

For newborns and infants (0–6 months) this ingredient has low overall toxicity in studies, but it can sometimes irritate skin, eyes or breathing and it can make the skin absorb other ingredients more easily. Because babies’ skin is very delicate, extra caution is recommended.

What to Do

If possible, avoid products with this ingredient on newborns and young babies. If you must use a product that contains it, choose a product made for babies, use it sparingly, do not apply to broken or red skin, avoid the face and eye area, and do a small patch test on the baby’s arm and wait 24 hours before wider use. Stop use and call your pediatrician if you notice redness, rash, swelling, or any breathing changes.

⚠️Warnings

Safety reviews note limited evidence of skin, eye and respiratory irritation, and that this chemical can increase skin absorption (sources: Cosmetic Ingredient Review and European Chemicals Agency). Some product standards limit or restrict its use without extra safety data—this is why it’s best to avoid it on very young babies when possible. Watch for redness, rash, swelling, or fussiness after applying any new product.

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.
