Chemical Information
FooDB NameSodium benzoate
DescriptionAntimicrobial preservative in foods, e.g. margarine and artificially sweetened fruit preserves. Flavouring agent and adjuvant Sodium benzoate is a preservative. It is bacteriostatic and fungistatic under acidic conditions. It is used most prevalently in acidic foods such as salad dressings (vinegar), carbonated drinks (carbonic acid), jams and fruit juices (citric acid), pickles (vinegar), and condiments. It is also found in alcohol-based mouthwash and silver polish[citation needed]. It can also be found in cough syrups like Robitussin. Sodium benzoate is declared on a product label as 'sodium benzoate' or E211.
