• 説明

  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.

• 化学的特性

  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.

• 使用

  Pharmaceutic aid (preservative).

• 調製方法

  Potassium benzoate is prepared from the acid–base reaction between benzoic acid and potassium hydroxide.

• 応用例（製薬）

  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.

• 安全性プロファイル

  Combustible when exposed to heat or flame. When heated to decomposition it emits acrid smoke and irritating fumes.

• 安全性

  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.

• 貯蔵

  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.

• 純化方法

  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.]

• 不和合性

  Potassium benzoate is incompatible with strong acids and strong oxidizing agents.

• 規制状況(Regulatory Status)

  GRAS listed. Accepted as a food additive in Europe. Included in the Canadian List of Acceptable Non-medicinal Ingredients.
