In the pharmaceutical industry, the safety, stability, and effectiveness of medicines depend not only on active ingredients but also on excipients—substances that support the formulation. Sodium benzoate is one such excipient that plays a critical role, particularly as a preservative in liquid medications like syrups and suspensions.
This blog explores the uses of sodium benzoate for pharmaceutical applications, its benefits, regulatory grades (IP/BP/USP), and why choosing a reliable supplier like Akshat Rasayan matters for medicine manufacturers.
What is Sodium Benzoate?
Sodium benzoate is the sodium salt of benzoic acid, a white, odorless, and crystalline powder. It is highly soluble in water and has powerful antimicrobial properties. Its primary function in pharmaceutical formulations is as a preservative, preventing the growth of bacteria, yeast, and fungi, which can degrade the product and pose risks to patients.
Sodium Benzoate for Pharmaceutical Use: Key Applications
Let’s look at the major pharmaceutical uses of sodium benzoate:
1. Preservative in Cough Syrup Formulation
Cough syrups, being aqueous and sugar-rich, are prone to microbial contamination. Sodium benzoate helps prevent this by maintaining microbial stability over time, even after the bottle is opened. That’s why sodium benzoate for cough syrup formulation is a standard ingredient in the pharmaceutical industry.
2. Used in Oral Liquids and Suspensions
Apart from syrups, sodium benzoate is commonly used in antacids, vitamin tonics, and iron supplements to extend shelf life and preserve quality.
3. Buffering Agent in Formulations
Sodium benzoate can act as a pH adjuster, keeping formulations stable under varying storage conditions.
4. Application in Pediatric and Geriatric Medicines
Since sodium benzoate is safe at regulated doses, it is used in formulations meant for children and the elderly, who often need liquid medications instead of tablets or capsules.
Grades of Sodium Benzoate for Pharma Use
In pharmaceuticals, purity and compliance with global pharmacopeia standards are essential. Sodium benzoate must meet one or more of the following standards:
- IP (Indian Pharmacopoeia) – used by Indian pharmaceutical companies.
- BP (British Pharmacopoeia) – followed by UK and Commonwealth countries.
- USP (United States Pharmacopeia) – recognized across the USA and Latin America.
At Akshat Rasayan, we supply sodium benzoate IP/BP/USP grade that matches stringent specifications required for pharmaceutical manufacturing.
Why Bulk Sodium Benzoate is Essential for Medicine Manufacturers
Pharmaceutical manufacturers working on a large scale need consistent, high-purity ingredients delivered on time. Choosing bulk sodium benzoate for medicine manufacturers ensures uninterrupted production lines and cost-effectiveness.
Some advantages of sourcing in bulk from trusted suppliers like Akshat Rasayan include:
- Consistent quality across batches
- Faster production cycles
- Cost savings in formulation
- Regulatory-compliant ingredients
Efficient supply chain management

Safety and Dosage in Pharmaceuticals
Sodium benzoate is approved by international health authorities like the FDA, WHO, and EMA for use as a preservative. However, its usage must follow the prescribed limits, typically:
- Up to 0.1% concentration in liquid pharmaceutical formulations
- Always combined with proper pH buffering (optimal below pH 4.5 for maximum effectiveness)
It is considered safe when used as directed, with low toxicity and minimal allergenic potential.
