Potassium benzoate Chemical Properties,Uses,Production
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.
Chemical Properties
Potassium benzoate occurs as a slightly hygroscopic, white, odorless or nearly odorless crystalline powder or granules. Aqueous solutions are slightly alkaline and have a sweetish astringent taste.
Uses
Pharmaceutic aid (preservative).
Production Methods
Potassium benzoate is prepared from the acid–base reaction between benzoic acid and potassium hydroxide.
Pharmaceutical Applications
Potassium benzoate is predominantly used as an antimicrobial
preservative in a wide range of beverages, foods and some
pharmaceutical formulations. Preservative efficacy increases with
decreasing pH; it is most effective at pH 4.5 or below. However, at
low pH undissociated benzoic acid may produce a slight though
discernible taste in food products.
Increasingly, potassium benzoate is used as an alternative to
sodium benzoate in applications where a low sodium content is
desirable.
Therapeutically, potassium benzoate has also been used in the
management of hypokalemia.
Safety Profile
Combustible when exposed to heat or flame. When heated to decomposition it emits acrid smoke and irritating fumes.
Safety
Potassium benzoate is widely used in food products and is generally
regarded as a nontoxic and nonirritant material. However, people
with a history of allergies may show allergic reactions when exposed
to potassium benzoate. Ingestion is inadvisable for asthmatics.
Higher concentrations of potassium benzoate have been reported to
cause irritation to mucous membranes.
The WHO acceptable daily intake of total benzoates including
potassium benzoate, calculated as benzoic acid, has been estimated
at up to 5 mg/kg of body-weight.
storage
Potassium benzoate is stable at room temperature under normal storage conditions. Since it is slightly hygroscopic, potassium benzoate should be stored in sealed containers. Exposure to conditions of high humidity and elevated temperatures should be avoided.
Purification Methods
Potassium benzoate [582-25-2] M 160.2. Crystallise it from water (1mL/g) between 100o and 0o. [Beilstein 9 III 375, 9 IV 279.]
Incompatibilities
Potassium benzoate is incompatible with strong acids and strong oxidizing agents.
Regulatory Status
GRAS listed. Accepted as a food additive in Europe. Included in the Canadian List of Acceptable Non-medicinal Ingredients.
