Description

 

Sodium benzoate is the sodium salt of benzoic acid and exists in this form when dissolved in water. It is a preservative. It is bacteriostatic and fungistatic under acidic conditions. It is used most prevalently in acidic foods. It is also found in alcohol-based mouthwash and silver polish. It can also be found in cough syrups like Robitussin. Some shampoos such as Pert 2-in-1 contain sodium benzoate as well. It is also used in fireworks as a fuel in whistle mix, a powder that emits a whistling noise when compressed into a tube and ignited. The fuel is also one of the fastest burning rocket fuels and provides a lot of thrust and smoke.
