Product Description

Benzoic acid is an organic compound of aromatic acids and the simplest aromatic acid, with the formula C7H6O2. Originally made from benzoin gum, so called benzoin acid. The melting point is 122.13 ºC, the boiling point is 249.2 ºC, and the relative density (15/4 ºC) is 1.2659. The appearance is white acicular or scaly crystal. It will sublimate above 100 ºC. Slightly soluble in cold water, hexane, hot water, ethanol, ether, chloroform, benzene, carbon disulfide and turpentine, etc.
Benzoic acid exists widely in nature in the form of free acids, esters or their derivatives. It is mainly used in the preparation of sodium benzoate preservatives, and used in the synthesis of drugs, dyes, but also used in the production of plasticizers, mordants, fungicides and spices. It can be prepared by direct oxidation of toluene in the presence of manganese dioxide, or by decarboxylation of phthalic anhydride with water vapor.

its application in foods and beverages, benzoic acid can also be added to cosmetics and pharmaceuticals for preservation
1.Benzoic acid is used in the preservation of food. Example - salad dressings, soft drinks, fruit juices and pickles. Usually, processed food has benzoic acid to inhibit the growth of bacteria, mould and yeast.
2.Benzoic acid 210 is used in pharmaceuticals. It is used as a preservative in drugs. It is also present in baby products, skin products, cleansing products, hair and nail products, soaps, bath products, detergents etc.
3.It helps in the prevention of bacterial infection. It is used as an antifungal for treating diseases like ringworm and athlete's foot. It is excreted as hippuric acid after conjugation with glycine in the liver. The excreted hippuric acid is not highly toxic. It is used in the treatment of skin irritation caused by insect bites, burns etc.
4.Used in toothpaste, jam, beverages, poultry, agriculture, perfume, dye etc.
