Sodium Benzoate is the sodium salt of benzoic acid. One gram of salt is soluble in 2ml of water, in 75ml of ethyl alcohol, and in 50ml of 90% ethyl alcohol. The salt is insoluble in ethyl ether. A typical aqueous solution will be slightly alkaline and typically has a sweetish astringent taste. Sodium Benzoate is a slightly hydroscopic, white, odorless or nearly odorless product. Sodium Benzoate contains 84.7% of available benzoic acid.
