Production Process
Potassium benzoate is synthesized through the neutralization of benzoic acid with potassium hydroxide. The process includes:
- Neutralization: Benzoic acid reacts with potassium hydroxide to form potassium benzoate.
- Purification: The solution is filtered and purified to remove impurities.
- Drying & Packaging: The final product is dried into a powder or granules and packaged for industrial use.
Industrial Applications
Potassium benzoate is extensively used in various industries, including:
- Food Industry: Commonly used in carbonated beverages, fruit juices, and condiments as a preservative.
- Pharmaceuticals: Used in medicinal formulations to prevent microbial contamination.
- Cosmetics: Incorporated into skincare and personal care products for extended shelf life.
