Description
Bacteriostatic water is specifically designed to maintain sterility when it comes into contact with medications or peptides that need to be reconstituted or diluted. The presence of benzyl alcohol helps prevent bacterial growth and contamination, which is crucial for injectable substances. It is important to note that bacteriostatic water is not sterile water and should not be used for other purposes that require completely sterile conditions, such as wound cleaning or eye care.
Typical Composition of Bacteriostatic Water in Vials:
- Water for Injection:
- The primary component of bacteriostatic water is sterile water, which is specifically designed for use in preparing injections. It ensures that the solution is free from contaminants, making it safe for injecting substances.
- Benzyl Alcohol (typically 0.9%):
- Benzyl alcohol is the antimicrobial agent commonly used in bacteriostatic water. It is usually present in a concentration of around 0.9%. This small amount of benzyl alcohol helps prevent bacterial growth, allowing the water to be used multiple times for reconstitution of medications.
- Important note: Although it is effective in preventing bacterial contamination, benzyl alcohol can cause allergic reactions in sensitive individuals, and its use is not recommended in newborns or infants due to potential toxicity.
