Understanding Bacteriostatic Water

What bacteriostatic water is, how it differs from sterile water, and how BioPure approaches quality and handling.

By BioPure Labs

A BioPure bacteriostatic water multi-dose vial

Bacteriostatic water is sterile water that contains 0.9% benzyl alcohol as a preservative. The preservative is what distinguishes it from plain sterile water and is the reason it is packaged for multi-dose access.

How it differs from sterile water

Plain sterile water contains no preservative. Bacteriostatic water adds benzyl alcohol, a common preservative used to support repeated access to a single container over its labeled period of use.

Always follow the product labeling

Storage, handling, and appropriate use are governed by the product labeling and applicable professional guidance. This article is informational and is not medical advice.

How BioPure approaches quality

  • Clear, clinical multi-dose vials with a tamper-evident flip-cap.
  • Manufactured under controlled quality processes.
  • Labeled with contents and handling information.

What is the preservative in bacteriostatic water?

0.9% benzyl alcohol, which is what allows it to be classified as bacteriostatic rather than plain sterile water.
