For toddlers (1-2 years) this ingredient is usually low risk when used in normal shampoos and lotions. It helps soften hair and skin and is not commonly linked to serious problems at the low levels used in products.
Use products with this ingredient as directed. Prefer rinse-off products (shampoos/conditioners) over leave-on if you are worried. Stop using the product if your child gets a rash, persistent redness, itchy skin, or any breathing trouble. For spray products, avoid spraying near your child’s face to reduce breathing exposure.
Some animal and lab studies have shown reproductive or nerve-cell effects and there are limited reports of respiratory or allergic reactions (sources: Cosmetic Ingredient Review and published studies from 2014, 2015, 2016 and 2021). Also, expert review lists safe use with concentration limits. Because of those findings, avoid using high-concentration products, avoid applying to broken or raw skin, and watch closely for any rash, swelling, wheeze or difficulty breathing. If you see those signs, stop use and seek medical advice.
