Potassium Benzoate / What is potassium benzoate

Potassium benzoate(E212) widely used as food additives and preservatives. its appearance is powder or crystal powder. it is Odorless or almost odorless, soluble in water and ethanol. Purity is more than 99%. the potassium benzoate formula is C7H5KO2, Molecular weight is 160.2, CAS NO.582-25-2

In general , the most popular presevative is Sodium benzoate, but why we produce Potassium benzoate, because it also have potassium, it can supplement our health. And potassium benzoate also can be as Firework material tweet agent in industrial.

A very common way to make potassium benzoate is to oxidize toluene to benzoic acid and then neutralize it with potassium hydroxide. Another method to synthesize potassium benzoate in laboratory is to hydrolyze methyl benzoate with potassium hydroxide

Potassium benzoate is stable at room temperature under normal storage conditions. Due to its slight hygroscopicity, it should be placed in a sealed container and should avoid exposure to high humidity and high temperature

Potassium benzoate has low acute toxicity after oral and skin contact. Food Safety Agency (Food Commission) calls for safer and healthier foods in food, which describes potassium benzoate as “mildly irritating to the skin, eyes and mucous membranes “.

The tolerance of cat to benzoic acid and its salt was significantly lower than that of rats and mice.

In some cases, for example in the presence of ascorbic acid, benzoate produces benzene in soft drinks. According to the U.S. Food and Drug Administration (US Food and Drug Administration), measured do not pose a safety hazard to consumers.

Potassium Benzoate Side Effects

Possible side effects
That is, the compound has potential side effects.
Chemical benzene may be formed when foods or beverages containing potassium benzoate and ascorbic acid are exposed to heat or light.
Benzene-containing foods may cause urticaria or severe allergic reactions, especially in people who are prone to eczema, itchy skin or long-term nasal congestion or runny nose
Overall, further research is needed to determine the health effects of the preservative.
