Product Specifications (Popular Food Grade)

Physical Properties & Appearance

Benzoic acid sodium salt presents as white crystalline solid with powder and granular appearances. The material is odorless or possesses a faint aromatic odor. It is highly soluble in water and slightly soluble in ethanol and other organic solvents. Aqueous solution of the compound shows weak alkalinity. This chemical has slight hygroscopicity under humid ambient conditions and remains stable under normal temperature and sealed storage environments. No obvious melting point is observed, and thermal decomposition occurs at temperatures above 300℃. Acidic environments will trigger chemical reactions that precipitate free benzoic acid.

Product Applications

Benzoic acid sodium salt serves as a multifunctional antibacterial preservative and chemical intermediate covering multiple industrial fields:

Food Industry: Standard E211 food preservative for beverages, fruit jams, pickled foods, sauces and canned products, inhibiting the reproduction of mold, yeast and bacteria to effectively extend product shelf life

Cosmetic Industry: Safe antibacterial additive for skincare creams, lotions, shampoos and oral care products to prevent microbial deterioration

Pharmaceutical Industry: Preservative for liquid pharmaceutical preparations and external ointments, also used as a synthetic auxiliary intermediate in drug manufacturing

Fine Chemical Industry: Essential raw material for organic synthesis, and mildew-proof stabilizer for water-based coatings, adhesives and printing inks

Water Treatment Industry: Bacteriostatic and corrosion-resistant auxiliary agent for industrial circulating water treatment systems

REACH Registration & Safety Document Support

Benzoic acid sodium salt has completed EU REACH registration to meet European market access standards. Complete certification files and standard MSDS download resources fully comply with international shipping specifications and overseas import inspection requirements.

FAQ

1. What chemical reaction will occur when Benzoic acid sodium salt contacts acidic substances? Contact with acidic solutions will trigger chemical reaction of Benzoic acid sodium salt, precipitating free benzoic acid solids and weakening its preservative effect, so isolation from acidic goods is required during storage and transportation.

2. What factors mainly affect the preservation performance of this sodium salt compound? Preservative activity is closely related to solution pH value. The compound delivers optimal antibacterial performance in weakly acidic environments, while neutral and alkaline conditions will reduce its bacteriostatic efficiency.

3. Is the MSDS download resource applicable for European market import declaration? Standard MSDS download files match REACH registration standards, which are fully recognized for customs declaration, safety audit and market circulation in European regions.
