For infants and newborns (0–6 months): sodium hydroxide is a strong chemical that can burn or irritate when concentrated. In baby lotions and cleansers it is usually used in tiny amounts to set the product’s acidity and is neutralized in the finished product. Still, because babies have very thin, delicate skin, this ingredient is more worrisome for newborns than for older children or adults.
If you are shopping for a baby (newborn, infant, 0–6 months): - Prefer products specifically labeled for babies or newborns from reputable brands. These are more likely to control pH and limit amounts. - Do not use household products that contain sodium hydroxide (drain cleaners, heavy cleaners) on or near your baby’s skin. Keep those well out of reach. - If a baby product lists this ingredient, avoid applying it to broken or irritated skin. Use a small amount on a small area only if the product is clearly intended for infants. - Stop use and rinse gently with water and contact your pediatrician if you see redness, burning, blistering, or any sudden change in the baby’s skin after use.
What to watch for and avoid: - Avoid products that don’t state they are safe for infants or do not list how they control pH — regulatory guidelines (for example EU cosmetics rules and industry safety panels) require limits and proper formulation for safe use. - Watch for signs of irritation to skin, eyes or breathing trouble; sources note limited evidence of irritation risk. - Never let the baby touch or mouth products that are not baby-formulated, and keep concentrated forms (cleaners) far away — those are corrosive and dangerous if touched or swallowed. If you have concerns, consult your pediatrician before using a product that contains this ingredient on a newborn or young baby.
