Useful:

• Description: Potassium benzoate is the potassium salt of benzoate. It is mostly used for food preservation for inhibiting the growth of mold, yeast and bacteria since it can create low pH condition after entering into the cells to suppress the anaerobic fermentation of glucose. It can also be used in the whistle in many fireworks. In analytic chemistry, it can be used as eluents for ion chromatography to increase the detector response.
• Uses: 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. Pharmaceutic aid (preservative).
