ℹ️General Overview

For school-age children (5 years and older) this ingredient carries a moderate level of concern. Some health authorities limit how it can be used in cosmetics and there isn’t strong safety data for products that stay on the skin.

✅What to Do

If you see this ingredient on a product for your child: avoid daily or long-term use; prefer rinse-off products over leave-on creams or lotions; do a small patch test on a clean area of skin and wait 24–48 hours before wider use; don’t use on broken, irritated, or inflamed skin; choose products without this ingredient when possible, especially for regular use.

⚠️Warnings

Regulatory reviews (Health Canada and other safety panels) restrict or limit its use in cosmetics; a European agency has flagged possible reproductive or developmental concerns at some exposures; industry safety reviews note limited data for leave-on products — these are the sources behind the caution. Also be aware there is limited evidence of skin irritation or allergic reactions (noted by European regulators). If you notice redness, swelling, itching, or any unusual reaction, stop use and consult your child’s healthcare provider.

Safety Risk Labels

This ingredient has the following documented risks:

Fertility: A European chemical agency (ECHA) flagged this ingredient as a possible human reproductive or developmental toxin. That means it may harm future fertility or other reproductive health if people are exposed.
Brain Development: The same European agency (ECHA) identified possible developmental harm. Developmental toxicity can include effects on early growth, including the brain, so this is a real concern for young children.
Banned: Health Canada and EU cosmetics rules put limits or bans on its use in cosmetics, industry reviewers note strict concentration limits, and the FDA prohibits it in food. Multiple agencies restrict or disallow this ingredient in some uses.
Absorbed: EU workplace hazard rules set low allowed exposures and hazard labels for workers, which shows the chemical can be harmful with contact and may get into the body during handling.
