For a 6–12 month old baby this ingredient is usually low risk, but there is a small chance it could irritate sensitive baby skin and there is a higher concern about trace contaminants from manufacturing (ethylene oxide and 1,4‑dioxane). Overall: probably OK in small amounts in reputable baby products, but take simple precautions.
Choose baby products made for sensitive skin and fragrance-free. Prefer products from companies that test for impurities or label products as free of ethylene oxide/1,4‑dioxane when possible. For a new product, apply a very small amount to a patch of the baby's inner forearm and wait 24 hours to check for redness or rash before using more widely. Avoid using on broken, red or eczema-prone skin. Use sparingly — especially with leave-on products — and avoid daily full‑body use of products that list this ingredient until you know the baby's skin tolerates it.
Watch for any redness, swelling, blisters, or ongoing rash after use — stop the product and contact your pediatrician if these occur. The primary concern comes from possible trace contaminants (ethylene oxide and 1,4‑dioxane) that can be left behind during manufacturing; this has been noted in safety reviews by Cosmetic Ingredient Review and regulatory/environmental agencies such as Environment Canada and the U.S. FDA. Also note that some product verification programs restrict this ingredient unless impurity testing is provided, so choosing products with clear impurity testing or baby-specific formulations reduces risk.
