Applicazioni
Potassium Benzoate is manufactured primarily for food and beverage use. It is a chemical preservative, which in very low concentrations inhibits the activity of the microorganisms. It is used in carbonated beverages. The shelf life of un-pasteurized cider can be greatly extended by adding potassium benzoate. It is also used as the whistle in many fireworks.
Note
Hygroscopic. Protect from humidity and water. Store under dry inert gas away from oxidizing agents and moisture.
