Common Beneficial Uses of Benzoic Acid
The acid which is derived from benzoin tree has a number of beneficial qualities including the ability to prevent the growth of bacteria and fungus. It is therefore widely used as a food preservative all over the world. Sodium benzoate, a salt derived from the acid is one of the most common preservatives used in jams, sauces and juices.

The acid present in these medications helps to prevent the attack of bacteria and also cures it completely.
In addition to the above mentioned uses and advantages, it is also widely used for manufacturing various chemicals. It is often combined with phosphorous and chloride to manufacture chemicals which are quite poisonous. It is also used for manufacturing pesticides and insecticides.
