Sodium Benzoate is a common preservative found in many toiletries and wet wipes. While there is public concern regarding its potential to form benzene, scientific consensus generally indicates that in topical baby products, the concentration is low and does not pose a carcinogenic risk through typical use. If you are concerned, focus on using fragrance-free, hypoallergenic products and ensure your baby’s skin is kept cool, clean, and dry to minimize the need for heavy product use.
