For children 2–5 years old (toddlers and preschoolers): this ingredient is a hair conditioner. There are some safety concerns mainly about manufacturing impurities and possible irritation or allergic reactions. It is usually lower risk in shampoo-type (rinse-off) products but is not recommended for products that stay on the skin.
Prefer rinse-off products (shampoos) that list this ingredient rather than leave-on creams or leave-in hair products. Avoid products meant for daily leave-on skin use or products applied near the eyes. Do a small patch test on the forearm and wait 24 hours before regular use. Choose products made for children or from brands that state they control impurities. If you can, pick products labeled for sensitive skin or formulated specifically for toddlers.
Stop use and wash the area if you see redness, rash, swelling, or eye irritation. The main reasons for caution are manufacturing impurities (3-dimethylaminopropylamine and nitrosamines) and industry recommendations to restrict use in leave-on products — this comes from Cosmetic Ingredient Review and a 2019 safety assessment of related chemicals. Also watch for signs of an allergic reaction (hives, persistent redness, or worsening irritation). If you see those, contact your pediatrician.
