For school-age children (5 years and older), this ingredient is usually low risk when used in rinse-off products like shampoos and body washes. Most health reviews find low concern for cancer, allergy, or developmental harm. The bigger worry is small amounts of manufacturing impurities that can sometimes be present.
Prefer rinse-off products (soaps, shampoos) that list this ingredient rather than leave-on lotions for children. Buy from brands that test for or declare they check for contaminants (manufacturing impurities). If trying a new product, do a small skin patch first and rinse off if you see redness or irritation. Stop use and ask your pediatrician if your child develops a rash or persistent irritation.
Watch for skin irritation or redness and stop use if it appears. The main caution comes from possible contamination with ethylene oxide and 1,4-dioxane (manufacturing impurities) — this is noted in safety reviews and environmental agency notes (Cosmetic Ingredient Review and Environment Canada). Also be aware that some product verification programs restrict use of this ingredient unless manufacturers provide extra testing or proof of purity; prefer brands that share contaminant testing or avoid this ingredient in leave-on products for kids.
