Bacteriostatic Water for Injection (BAC Water) is sterile, non-pyrogenic water that contains a small amount (typically 0.9% benzyl alcohol) as a preservative. It is used as a diluent to reconstitute or mix medications—most commonly peptides, hormones, and other injectable compounds—prior to subcutaneous or intramuscular injection.
Composition
- Water for Injection (WFI): Sterile and purified
- Benzyl Alcohol (0.9%): Acts as a bacteriostatic agent, inhibiting bacterial growth and allowing multi-dose use
