Purox B Benzoic Acid Food/PharmaEmerald produces Purox® B Food/Pharma benzoic acid using the highest quality standards and an unmatched purification process.


As a result, we offer the highest purity of benzoic acid available worldwide (99.98% minimum). Purox B Food/Pharma is primarily used as a nature identical preservative, safely inhibiting the growth of bacteria, yeasts, and molds. Its excellent chemistry
profile benefits food, cosmetic, personal care, and
pharmaceuticals manufacturers.


Purox B Food/Pharma is produced under an FSSC 22000 certification at our world-scale, food-grade operation and meets specifications for key global pharmacopeia (EP, USP, JCP), National Formulary (NF), and FCC. It is a green label solution, authorized for use under programs such as ECOCERT, COSMOS, EU Ecolabel, and Nordic Swan.


Because of its exceptional purity, Purox B Food/Pharma offers excellent characteristics, such as low odor, no discoloration, and low agglomeration. For water-based systems, benzoate salts can provide the preservation power of benzoic acid with improved solubility.
