Sodium Benzoate Storage — E211 Food Preservative Tank Selection

Storing Sodium Benzoate? Start Here

Sodium benzoate is a widely used preservative found in foods, cosmetics, and pharmaceuticals. It comes as a white crystalline powder and dissolves easily in water, making it straightforward to handle and store. Whether you're in the food processing industry or managing a pharmaceutical plant, understanding how to store sodium benzoate safely will ensure its effectiveness and longevity.

Can you store it in a poly tank?

Yes, sodium benzoate can be safely stored in polyethylene tanks. It is compatible with a wide range of materials, including HDPE, XLPE, and other common polymers, making poly tanks a suitable choice for storage.

Watch Out for Cold Temperatures

While storing sodium benzoate, be aware that concentrated solutions can crystallize at temperatures below 30°F. If you're in a cold climate, consider using heat tracing to prevent this issue and maintain the solution's stability.

The safety that actually matters

  • Ensure proper labeling to avoid confusion with other substances.
  • Store in a dry, cool place to maintain its quality.
  • Use appropriate personal protective equipment when handling.

Common questions

Is sodium benzoate safe for food use?
Yes, it is generally recognized as safe (GRAS) by the FDA for use in food at specified levels.
Can sodium benzoate cause any reactions?
While rare, some individuals may have hypersensitivity reactions. It's important to label products accordingly.
What if my storage area is very cold?
Consider installing heat tracing to prevent crystallization of concentrated solutions in cold environments.
