For newborns and babies 0–6 months: sodium benzoate is a preservative that is generally considered low risk at the small amounts used in skin products, but infant skin is delicate so we take extra care.
Choose products made for infants or labeled for newborn use. Prefer rinse-off products (like baby wash) over leave-on lotions that contain sodium benzoate. If you must use a leave-on product with this ingredient, use it sparingly and not every day on a large area. Keep products away from the baby’s eyes, mouth, and any broken skin.
Watch for redness, irritation, rash, or swelling after use — stop use if these occur. The caution about concentration limits and restricted uses comes from industry safety reviews and some national regulations (Cosmetic Ingredient Review and Japan’s health authority). There are also notes about data gaps from some government reviews (for example, the EPA) and some product certification programs restrict its use without extra testing. If your baby has very sensitive skin or eczema, avoid this ingredient or consult your pediatrician before use.
