Description and specifications
Description
Bacteriostatic water is sterile water with 0.9% benzyl alcohol added as a preservative, intended for reconstituting and dissolving lyophilised peptides in the laboratory. The benzyl alcohol inhibits bacterial growth, so solution can be taken from the same vial several times over a period. Supplied in 3 ml or 10 ml vials. For laboratory use only. Not for injection, consumption or therapeutic use.
Research summary
Bacteriostatic water, often called bac water, is sterile water with 0.9% benzyl alcohol added. It is used as a solvent when lyophilised (freeze-dried) peptides are reconstituted in the laboratory. The difference from ordinary sterile water is the preservative: benzyl alcohol makes the water bacteriostatic, meaning it inhibits bacterial growth, so that an opened vial can be used over time rather than having to be used up in a single operation. This page explains the product's role in batch, COA and laboratory handling, and does not give injection or usage instructions.
Level of evidence: This is an excipient, not a research peptide. This page should be assessed on product quality, sterility, COA and laboratory procedures, not on molecule-specific efficacy studies.

Read the full guideBacteriostatic water (0.9% benzyl alcohol in sterile water)
Bacteriostatic means inhibiting, not killing. Benzyl alcohol acts as a preservative and can limit microbial growth in multi-dose containers under controlled laboratory conditions, but it does not sterilise a vial that is already contaminated; sterile equipment and clean technique remain essential. The 0.9% concentration is the established standard for multi-dose containers and is the same in both 3 ml and 10 ml vials; the size only determines how many reconstitutions one vial covers.
