Benzoic Acid aids in the prevention of bacterial infection. The body sheds rough or dead skin cells with the aid of salicylic acid. It is a frequently used antimicrobial preservative in food and drinks, particularly carbonated ones. This is used to treat skin inflammation and irritation brought on by burns, insect bites, fungal infections, or eczema. Benzoic Acid has its best antibacterial action within a pH range of 2.5 to 4.0. This is very effective as well as economical to use.
