Bacteriostatic Water vs Sterile Water
During peptide reconstitution, two commonly used solutions are sterile water and bacteriostatic water. The choice between them depends on the user’s preference, but there are notable differences.
Differences Between Bacteriostatic Water vs. Sterile Water
Bacteriostatic water differs from sterile water in that it can be used multiple times within a 28-day period. This makes it particularly popular among scientists. Bacteriostatic water is non-pyrogenic, meaning it does not induce fever when introduced into the body. It contains approximately 0.9% benzyl alcohol, an aromatic alcohol that has a hydroxyl group indirectly bonded to an aromatic compound, giving it a pleasant smell. This composition prevents bacterial growth, allowing the solution to be reused safely over time.
On the other hand, sterile water is also non-pyrogenic but can only be used once. After opening, it must be discarded. Sterile water is a good alternative when the body does not tolerate bacteriostatic water well.
