About this product
Sodium Benzoate (CAS 532-32-1) is the sodium salt of benzoic acid — a white crystalline or granular powder, freely soluble in water, used as an antimicrobial preservative. Buyers know it as E211 or INS 211; it is a standard preservative in liquid oral pharmaceutical formulations, syrups and water-based food and beverage products. We stock IP grade material (per IP-2022, Amendment 2024) in 25 kg bags at our Redhills warehouse in Chennai, with dispatch across South India.

Frequently Asked Questions
What is sodium benzoate used for?
Sodium benzoate is an antimicrobial preservative. It is used in liquid oral pharmaceutical formulations, syrups and water-based food and beverage products, where its free solubility in water makes it easy to incorporate.
What is the CAS number of sodium benzoate?
The CAS number for sodium benzoate is 532-32-1. Its HSN code for Indian customs and GST purposes is 2916 31 20.
What is the difference between sodium benzoate and benzoic acid?
Sodium benzoate is the sodium salt of benzoic acid — benzoic acid is converted into sodium benzoate and other benzoate salts. The salt is freely soluble in water, which is why water-based formulations use sodium benzoate rather than the parent acid. We supply both.
Is sodium benzoate the same as E211 or INS 211?
Yes. E211 and INS 211 are the food-additive codes for sodium benzoate, and 'benzoate of soda' is an older trade name for the same material. All refer to the sodium salt of benzoic acid, CAS 532-32-1.
What is the specification of IP grade sodium benzoate?
Our IP grade material is supplied against the manufacturer's certificate of analysis to IP-2022 (Amendment 2024): assay 99.0–101.0% on the dried basis by HPLC, loss on drying 2.0% max, heavy metals 10 ppm max, arsenic 2 ppm max and chlorinated compounds 25 ppm max. It is manufactured in India under the Drugs & Cosmetics Act 1945 at a GMP- and GLP-certified plant. Full figures are on our published TDS and MSDS.
How should sodium benzoate be stored, and is it hygroscopic?
Sodium benzoate is hygroscopic, so store it protected from moisture in well-closed containers. It is a low-hazard food and pharma preservative — avoid dust generation and keep it away from strong oxidisers.
Can I buy sodium benzoate in bulk in Chennai?
Yes. We stock sodium benzoate in 25 kg bags at our Redhills warehouse in Chennai and dispatch across South India. Order sizes depend on packaging and current stock — call or WhatsApp +91 86087 80096 for a quote.
