Product Description

1. Product Overview

Sodium Benzoate, also known as sodium benzenecarboxylate, coded E211, is a widely recognized broad-spectrum food preservative. It appears as white crystalline powder with slight odor of benzoic acid, easily soluble in water. Our product strictly complies with GB 1886.184, FCC, BP international food standards, purity ≥99.0%, no heavy metal excess, safe for food processing.

Basic Parameters:

• CAS No.: 532-32-1
• EINECS No.: 208-534-8
• Molecular Formula: C7H5NaO2
• Molecular Weight: 144.11
• HS Code: 2916310090
• Appearance: White crystalline powder
• Assay: 99.0%~100.5%

2. Antiseptic Principle

Sodium Benzoate exerts bacteriostatic and antifungal effects under acidic environment. It can inhibit the reproduction of yeast, mold and bacteria effectively, block microbial metabolic activity, so as to extend the shelf life of food products without changing original flavor. It works best when pH below 4.5, ideal for acidic food systems.
