Sodium Benzoate
What Sodium Benzoate Is
Introduction: Sodium benzoate, also known as sodium benzoate, is an organic compound. It is a white granule or crystalline powder with specific physical properties and is widely used in many fields, especially in food preservation.
Synonyms: sodiumbenzoicacid; femanumber3025; sodiumbenzoate; obenate;SODIUM BENZOATE;PUROX S; ucephan; BENZOTRON(R)
Chemical Properties: Sodium benzoate is an organic acid salt that can dissociate benzoate ions and sodium ions in water, so it is acidic. It is relatively stable at room temperature, but may decompose under high temperature, light or humid environment, resulting in a reduction in its antiseptic effect.
Reactivity and Uses: Sodium benzoate enters the cell body and ionizes and acidifies the alkali storage in the cell, inhibits the activity of the respiratory enzyme system of the cell, prevents the condensation reaction of acetyl-CoA, interferes with the permeability of the cell membrane, inhibits the absorption of amino acids by the cell membrane, and thus plays a role in food preservatives. Purpose.

The Applications of Sodium Benzoate
Pharmaceutical Industry
- Medicinal Uses: In the medical field, Sodium Benzoate is used in combination with salicylic acid to treat superficial fungal infections such as tinea manuum, tinea pedis, and tinea corporis. It is also often used as a preservative in pharmaceutical preparations to ensure that the drugs remain sterile during their use period.
Production Technology of Sodium Benzoate
Raw Materials Preparation
- Benzoic Acid
- Sodium Hydroxide (NaOH) or Sodium Carbonate (Na2CO3)
- Water
Production Process Steps
Dissolution
- Dissolve benzoic acid in an adequate amount of water to form a benzoic acid solution. Heating can be applied to accelerate the dissolution.
Neutralization Reaction
- Dissolve sodium hydroxide or sodium carbonate in water to form an alkaline solution.
- Gradually add the alkaline solution to the benzoic acid solution, allowing the neutralization reaction to occur, forming sodium benzoate and water.
Filtration
- After the neutralization reaction is complete, there may be undissolved impurities or by-products in the solution. Filter the solution to remove impurities.
Evaporation and Crystallization
- Heat the filtered solution to evaporate and concentrate it.
- During the concentration process, sodium benzoate starts to crystallize out.
- Control the evaporation temperature and concentration to obtain pure sodium benzoate crystals.
Separation and Drying
- Separate the crystallized sodium benzoate from the mother liquor, usually using a centrifuge or filter.
- Dry the separated sodium benzoate crystals to remove residual moisture.
Packaging
- Screen the dried sodium benzoate crystals to obtain uniform particles.
- Finally, package the finished sodium benzoate product for storage or shipment to customers.
Process Considerations
- Temperature Control: Proper temperature control during the neutralization reaction and crystallization process is crucial, as overly high or low temperatures can affect product quality and yield.
- Purity: Use high-purity raw materials and control impurity levels to ensure product quality.
- Safety Measures: Sodium hydroxide is highly corrosive; protective measures must be taken to prevent skin and eye contact during operation.
Quality Control
- Product Purity: Analyze product purity using chemical analysis methods, such as titration and chromatography.
- Physical Properties: Measure the product’s appearance, particle size distribution, solubility, and other physical properties.
- Safety Testing: Ensure the product meets safety standards for industries such as food and pharmaceuticals, including conducting microbiological testing.

Environment and Health
Environmental Impact
Biodegradability:
- Sodium benzoate is biodegradable. It breaks down in the environment through natural processes, primarily through microbial action in soil and water.
Aquatic Toxicity:
- Sodium benzoate can be toxic to aquatic organisms at high concentrations. It is essential to manage waste disposal and avoid discharging large amounts into water bodies.
Soil Impact:
- In soil, sodium benzoate is relatively mobile and can leach into groundwater. Proper disposal practices are necessary to minimize soil contamination.
Environmental Regulations:
- Sodium benzoate usage and disposal are regulated to prevent environmental pollution. Compliance with local environmental regulations and guidelines is crucial.
Health Impact
Toxicity:
- Acute Toxicity: Sodium benzoate has low acute toxicity. Ingestion of large amounts can cause gastrointestinal irritation, nausea, vomiting, and abdominal pain.
- Chronic Toxicity: Long-term exposure to low levels of sodium benzoate is generally considered safe. However, high doses over extended periods can potentially cause liver and kidney damage.
Allergic Reactions:
- Some individuals may experience allergic reactions to sodium benzoate, including skin rashes, itching, and asthma symptoms. It is advisable to avoid products containing sodium benzoate if you have a known sensitivity.
Carcinogenicity:
- Sodium benzoate itself is not considered carcinogenic. However, it can react with ascorbic acid (vitamin C) in acidic conditions to form benzene, a known carcinogen. Regulatory agencies have set limits on the allowable concentration of sodium benzoate and ascorbic acid in products to minimize this risk.
Regulatory Guidelines:
