Bacteriostatic water is commonly used for injection purposes, in order to dilute or dissolve substances such as reconstituting powdered substances. Bacteriostatic water is sterile water that contains 0.9% benzyl alcohol in order to stop the growth of any potential bacteria that could contaminate the sterile bacteriostatic water. Due to the antibacterial properties of the benzyl alcohol, the bottle can be drawn from multiple times through the use of a sterile needle. The water is considered “static” rather due to the addition of the benzyl alcohol which leads to stability of the solution and unchanging bacteria content. While bacteriostatic water is free of bacteria, it is considered different from normal sterile water since sterile, purified water has absolutely no additives in its composition.
