How Bacteriostatic Water Works

Bacteriostatic water is sterile water for injection containing 0.9% benzyl alcohol as a bacteriostatic preservative. The benzyl alcohol inhibits bacterial growth, allowing the vial to be used for multiple reconstitutions over an extended period. It is used as a diluent for reconstituting lyophilized peptides and medications. The benzyl alcohol disrupts bacterial cell membrane integrity and interferes with microbial metabolic processes, preventing contamination of multi-use vials.
