Sodium Benzoate can kill bacteria and inhibit bacterial growth. The change of PH value has a great influence on its effect, the effect is the best when the PH value is 2.5-4.5, and the effect is obviously reduced in the alkaline medium. It is widely used as a preservative in food, medicine, cosmetics, toothpaste, spices, tobacco and feed.
Sodium Benzoate (1.5%) is good at preventing rust and corrosion in automotive cooling systems, and can also be used to prevent metal corrosion in packaging pulp, latex coatings, lacquers, cutting oils and machines.
