Thanks for your question. The first section of the product page shows the ALLERGEN that makes the product rate as Not Safe - we do not list sodium benzoate as an ingredient. To see the SPECIFIC INGREDIENTS in the formula, scroll to the ingredient list—any ingredient causing the rating will be highlighted. In many cases, it isn’t the allergen itself but an ingredient that’s cross‑reactive with it.
