Description
Bacteriostatic water is water that has been sterilised and then had a small amount of benzyl alcohol added to it — 0.9% by weight is the standard concentration and the one in this vial. It is not a peptide and it is not an active compound of any kind. The benzyl alcohol is the only thing distinguishing it from plain sterile water.
Benzyl alcohol is bacteriostatic rather than bactericidal, and the distinction is the whole point of the name: it inhibits bacteria from multiplying rather than killing what is already present. It does this by disrupting bacterial cell membranes at a concentration low enough to leave the water otherwise inert. The practical consequence for the container is that a sealed vial does not have to be discarded the moment its seal is broken, which is why the preservative is there at all. It has no activity of its own beyond that, and it is not sterilising anything it is added to.
