CAS No.: | 532-32-1 |
Description
Sodium Benzoate occurs as white granules, crystalline powder, or flakes. One gram dissolves in 2mL of water, in 75mL of alcohol, and in 50mL of 90% alcohol.
Application
Sodium Benzoate is a highly effective preservative, odorless or with smell of benzoin and tasted sweet astringency. Antiseptic performance of 1.180g sodium benzoate is equivalent of about 1g benzoic acid. In acidic environment, it has obvious inhibitory effect on a variety of microorganisms, but it isn’t recommended as a preservative at pH ranges higher than 4.5. Sodium benzoate is widely used for preserving foods, beverages, pharmaceuticals and it is also used to preserve low alcohol (<15%) as well as non-alcoholic beer.
