For newborns and babies 0–6 months: benzoic acid is a preservative with low concerns in broad safety reviews, but expert panels limit how it can be used in products. Babies’ skin is delicate, so we should be cautious.
Prefer products made specifically for infants that do not list benzoic acid. If a healthcare provider recommends a product that contains it, use a very small amount on a small patch of skin first, wait 24–48 hours, and stop immediately if you see redness, swelling, a rash, or any irritation. Avoid use on broken skin, near the eyes, mouth or diaper area. For routine cleaning or moisturizing of newborn skin, choose products labeled for newborns without this preservative when possible.
There are official limits and recommendations about how benzoic acid may be used in cosmetics (Cosmetic Ingredient Review; Japan Ministry of Health). Some government reviews note data gaps and recommend limiting concentration or product types (Environmental Protection Agency; Cosmetic Ingredient Review). Watch for signs of skin irritation or allergic reaction in babies and stop use if they occur. If a product is marked as restricted by its certifier, do not use it on infants without asking a pediatrician.
