2-5 year old preschoolers • Skin contact product
For 2-5 year olds (toddlers and preschoolers), this preservative is not commonly linked to cancer or long-term developmental problems, but some countries limit or ban it and it can sometimes cause irritation. Be careful and prefer products made for young children.
If possible, choose products made and labeled for children or rinse-off products (like shampoos or body washes) rather than leave-on creams that contain this ingredient. Do a small patch test on the child’s inner forearm and wait 24 hours before wider use. Avoid applying to broken or irritated skin and keep away from the face and eyes. If you see any redness, swelling, itching, or breathing changes, stop use and talk to your child’s doctor.
Some government and expert safety reviews have restricted or banned this ingredient in certain cosmetic uses (see safety opinions from regulators such as the European cosmetics authority, Japan’s Ministry of Health, and industry safety reviews by the Cosmetic Ingredient Review). Those reviews also note limited safety data and possible skin/eye/lung irritation. Watch for signs of irritation (redness, rash, swelling, watery eyes, coughing or breathing trouble) and avoid use on injured skin or near the eyes. If a severe reaction occurs, seek medical care.
