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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
