For toddlers and preschoolers (ages 2–5), this ingredient can be safe when it’s used in very small amounts and the final product is pH-balanced for skin. It is a strong chemical by itself and can irritate or burn if concentrated or not properly neutralized.
Pick products labeled for young children or infants when possible. Prefer wipes, soaps, and creams made for kids and from reputable makers who list ingredients and say the product is pH-balanced or formulated to avoid irritation. Don’t use household products (like drain cleaners) that contain sodium hydroxide on skin. If a product causes stinging, redness, or peeling on your child’s skin, stop use and rinse the area with water. Keep any products and all household cleaners locked away and out of reach.
Avoid products that list sodium hydroxide as an active ingredient or that do not state they are safe for sensitive skin or children. Do not let children play with or apply products that smell strongly or burn. There are formal use limits and safety reviews under cosmetic rules and safety panels (for example the EU cosmetics rules and industry safety reviews) because of its potential to irritate or cause burns; health literature and hazard labeling also note possible skin, eye, and lung irritation (U.S. National Library of Medicine; EU hazard labeling). If your child gets a chemical burn or gets the product in their eyes, rinse immediately and seek medical help or call poison control.
