EC NUMBER: 209-481-3

MOLECULAR FORMULA: C7H5KO2

MOLECULAR WEIGHT: 160.21 g/mol

DESCRIPTION:

A very common way to make E 212 is to oxidize toluene to benzoic acid and then neutralize it with potassium hydroxide.
Another method to synthesize E 212 in laboratory is to hydrolyze methyl benzoate with potassium hydroxide
E 212 is stable at room temperature under normal storage conditions.
Due to its slight hygroscopicity, E 212 should be placed in a sealed container and should avoid exposure to high humidity and high temperature
E 212, the potassium salt of benzoic acid, is a food preservative that inhibits the growth of mold, yeast and some bacteria.
E 212 works best in low-pH products, below 4.5, where it exists as benzoic acid.
Acidic foods and beverages such as fruit juice (citric acid), sparkling drinks (carbonic acid), soft drinks (phosphoric acid), and pickles (vinegar) may be preserved with potassium benzoate.
E 212 is approved for use in most countries including Canada, the United States and the European Union, where it is designated by the E number E212.

E 212 is also used in the whistle in many fireworks.
E 212 is a preservative commonly added to food, beauty, and skin care products.
E 212 is a white, odorless powder that’s obtained by combining benzoic acid and potassium salt under heat.
E 212 is a compound naturally found in plants, animals, and fermented products.
Originally derived from the E 212 resin of certain tree species, it’s now mostly industrially produced.

E 212 salts are typically extracted from salt beds or certain minerals.
E 212 is a synthetic compound in some foods and drinks. Very small amounts can be safe to consume.
E 212 is typically used by food manufacturers as a chemical preservative.
E 212's sometimes used in place of a related preservative sodium benzoate to reduce the food's sodium content.
E 212 helps fight food spoilage, and it can contribute to food's flavor, but like any food additive, it can cause allergic reactions in some people.
