For toddlers and preschoolers (2-5 years), this ingredient is generally low risk when used in small amounts in creams, wipes, shampoos and similar products. It is a conditioning polymer that helps skin and hair feel softer.
Choose products labeled for children or 'gentle'. When possible, prefer rinse-off products (shampoos, body wash) over leave-on creams for large areas. Do a small patch test on the inside of the forearm and wait 24 hours before using more widely. Avoid putting the product on broken or very irritated skin. Use the smallest amount needed and do not apply repeatedly over the whole body every day.
Safety reviews (Cosmetic Ingredient Review) say it is safe with concentration and use limits and that leave-on and rinse-off uses may be treated differently. A government agency (Environment Canada) flagged possible environmental toxicity and reported findings classifying it as expected to be toxic or harmful in some studies; these concerns relate to higher exposures or environmental impact rather than normal small-scale skin use. If you see redness, swelling, itching, blisters, or breathing problems after using a product containing this ingredient, stop use and seek medical advice.
