Benzoate is a preservative found in foods, drinks, beauty products and other household items which can cause a contact allergic reaction.
Benzoate is associated with allergic contact dermatitis.
Sodium benzoate does not occur naturally in food, but benzoic acid is found in prunes, cinnamon, cloves, tea, tomatoes, plums, apples and cranberries.
