Description
What Bacteriostatic Water Is
Bacteriostatic water is sterile, non-pyrogenic water to which 0.9% w/v benzyl alcohol
(CAS 100-51-6) has been added as a bacteriostatic preservative. The benzyl alcohol
inhibits the growth of common bacterial contaminants, which is what distinguishes this
solution from plain sterile water and allows a sealed vial to tolerate multiple
withdrawals across a working period rather than a single entry.
It is a diluent, not a research compound. It carries no biological activity of its own
and is characterised entirely by its sterility, its preservative content, and the absence
of pyrogens.
Bacteriostatic Water vs. Adjacent Solutions
| Solution | Preservative | Entries | Distinguishing property |
|---|---|---|---|
| Bacteriostatic water | 0.9% benzyl alcohol | Multiple | Preservative suppresses bacterial growth between withdrawals |
| Sterile water for injection | None | Single | No preservative; sterility is not maintained after first entry |
| 0.9% sodium chloride (saline) | None (unless specified) | Single | Isotonic salt solution, not pure water; different osmolarity |
Specifications
| Property | Specification |
|---|---|
| Volume | 10 mL |
| Composition | Sterile water (CAS 7732-18-5) with 0.9% w/v benzyl alcohol (CAS 100-51-6) |
| pH | 4.5 – 7.0 (USP monograph range for benzyl-alcohol-preserved water) |
| Sterility | Sterile, non-pyrogenic |

Storage & Stability
Store at controlled room temperature, 20–25 °C, away from direct light. Unopened vials
are stable through the lot expiry printed on the label.
For benzyl-alcohol-preserved multi-dose solutions, USP convention limits the in-use
period to 28 days from initial entry. This is a property of the preservative system, not
a recommendation for any particular application.
Verification
Every lot ships with a Certificate of Analysis identifying the batch. Consistent with
how Artemis Labs handles every compound in the catalogue: we do not ask you to take
sterility on trust, we document it per lot.
Regulatory Status
This product is supplied strictly as a laboratory reagent. It is not a drug, is not
FDA-approved, and is not intended for human or veterinary use. Artemis Labs is not a
compounding pharmacy or an outsourcing facility, and does not supply this solution for
any clinical, diagnostic, or therapeutic purpose.

Frequently Asked Questions
Why does bacteriostatic water contain benzyl alcohol?
Benzyl alcohol is a bacteriostatic agent — it suppresses bacterial replication rather
than killing organisms outright. Its presence is what allows a sealed vial to tolerate
repeated withdrawals without the sterility failure that would follow the first entry into
an unpreserved solution.
How does it differ from sterile water?
Sterile water contains no preservative. It is sterile at the point of manufacture, but
that sterility is not maintained once the closure is pierced, which makes it a
single-entry solution. Bacteriostatic water is formulated for multiple entries.
What is the pH?
4.5 to 7.0, the USP monograph range for benzyl-alcohol-preserved water.
Is a Certificate of Analysis included?
Yes — lot-specific, with every order, as with every product in the catalogue.
How should it be stored?
Controlled room temperature, 20–25 °C, away from direct light.
