Shelf Life of Bacteriostatic Water: Does It Really Expire?
Bacteriostatic water is sterile water mixed with 0.9% benzyl alcohol, used to inhibit bacterial growth, allowing for multiple uses if stored correctly. It typically has a long unopened shelf life, over two years, but once opened, it should be used within 28 days for safety, as benzyl alcohol may lose effectiveness. Proper storage is crucial.
