For school-age children (5 years and older): PEG-150 is generally low risk when used on normal, unbroken skin in products from reputable brands. It is used as a thickener and usually does not cause cancer, allergy, or reproductive problems at common use levels.
Use products that list PEG-150 only when the product is intended for children and comes from a brand that tests for impurities. Do a small patch test on the child’s inner forearm and wait 24 hours before regular use. Never apply PEG-150 products to cuts, scrapes, or any broken or inflamed skin.
Watch for skin redness, itching, or rash after first uses and stop use if these occur. There are specific concerns about contamination by ethylene oxide and 1,4-dioxane reported by industry and government reviews, and some industry guidance says this ingredient should not be used on injured or damaged skin (source: Cosmetic Ingredient Review and Environment Canada; manufacturing and impurity guidance referenced by the U.S. Food and Drug Administration). Prefer products that state they test for or limit these impurities.
