For newborns and babies (0–6 months), this foaming ingredient can irritate very sensitive skin and eyes. It is more likely to cause dryness, redness, or a rash in infants than in older children or adults.
Prefer products labeled for infants that do not list this ingredient. If you must use a product that contains it, choose a rinse-off product (like a baby wash) made for babies, use a small amount, rinse thoroughly, and avoid using it on broken or very dry skin. Stop use and rinse well if you see redness, stinging, or a rash. When in doubt, choose SLS-free baby products.
Watch for skin redness, peeling, fussiness after bath, or eye irritation — these are signs of irritation reported by safety panels (Cosmetic Ingredient Review). Government assessments have also flagged potential non-reproductive organ concerns and environmental toxicity (Environment Canada). Safety depends on how much is in the product and whether it is rinse-off or left on the skin — product reviews note limits on concentration and that leave-on use carries more risk (Cosmetic Ingredient Review).
