It is insoluble in cold water and organic solvents, and slowly dissolves in alkaline solutions.

Products Description of Sodium benzoate CAS#532-32-1In 1870, when British scientist H. Fleck was looking for an acid to replace the well-known salicylic acid, he first described the antiseptic effect of benzoic acid. He established the antiseptic effect of this substance. Since the safety research of sodium benzoate was not in-depth at that time and the production technology was not mature enough, it was not used for food preservation until the beginning of this century. Since then, it has become one of the most used preservatives in the world because of its low price.
