Product Description

Products Description of Sodium benzoate CAS# 532-32-1

As a widely used food preservative, sodium benzoate is air-stable, hygroscopic, and naturally found in fruits and spices. It works best against microbes and yeast in acidic media, with little effect under neutral or alkaline conditions. Safe and non-accumulative within ADI limits, it is fully metabolized and excreted by the body. It is extensively applied in beverages, jams, sauces, margarine and confectionery for antimicrobial preservation.


Product Application of Sodium benzoate CAS# 532-32-1

As an efficient acidic preservative (E211), sodium benzoate inhibits bacteria and fungi in beverages, jams, pickles, dressings, pharmaceuticals and cosmetics. It is also used in fireworks and rocket propellants for combustion and thrust generation, and needs cautious handling owing to impact sensitivity.
