Benzoic acid is common additives to food, drinks, and other products. They are useful chemicals in manufactured products because they kill or inhibit both bacteria and fungi and can act as preservatives.
Benzoic acid is very pH dependent. While it shows some activity up to pH 6 (about 1.55%), it is most active at pH 3 (94%).
Benzoic acid is considered to be primarily an anti-fungal, but it shows some activity against bacteria. It is poor against pseudomonads. Benzoic acid is inactivated by non-ionics and by raising the pH.
