Bacteriostatic water is a sterile water solution that contains a small amount of a preservative, usually benzyl alcohol, which inhibits the growth of bacteria. It is commonly used for diluting or dissolving medications, particularly those that are intended for injection. Its bacteriostatic properties mean it can be used multiple times, provided the sterility of the solution is maintained.
