What is BAC Water?

Bacteriostatic water (BAC Water) is a sterile aqueous solution containing 0.9% benzyl alcohol as a preservative, formulated for dissolving lyophilized reference materials in laboratory settings. It is the standard reconstitution diluent in peptide research workflows requiring repeated sampling from a single vial.

The 0.9% benzyl alcohol preservative system inhibits microbial growth, extending post-puncture vial integrity to a 28-day window — a property that makes multi-withdrawal in vitro protocols operationally feasible. Researchers select this formulation specifically because it maintains sterility across sequential sampling without requiring single-use vials for each aliquot.

The research

What the research actually found

The published findings behind this compound — the headline numbers, in plain terms, each cited to source. Preclinical results are directional (animal / in-vitro) and shown for context, not as therapeutic claims.

Published research on the reference compound class. Provided for scientific context only — not a claim about the product supplied.

Sterility windowPreclinical

28 days

Per product specification, the 0.9% benzyl alcohol preservative system maintains post-puncture vial sterility for 28 days in vitro — supporting multi-withdrawal reconstitution protocols without requiring single-use vials for each aliquot.

Post-puncture sterility window — in vitro formulation spec

Full 28-day window supported by 0.9% (9 mg/mL) benzyl alcohol preservative system per manufacturer specification.

Preservative concentrationPreclinical

0.9%

The formulation contains 9 mg/mL benzyl alcohol (0.9% w/v) in sterile water — a concentration established by specification to sustain antimicrobial activity across the 28-day post-puncture window.

Enzymatic inhibitionPreclinical

In an in vitro dental substrate model, benzalkonium chloride — a structurally related quaternary preservative — inhibited matrix metalloproteinase (MMP) activity relative to an untreated control. The direction of effect is inhibitory; no quantified magnitude was extracted for BAC Water's specific formulation.

Mechanism

How BAC Water works

Bacteriostatic water maintains reconstituted peptide solution integrity through three distinct properties studied in laboratory diluent applications.

Microbial inhibitionbenzyl alcohol preservative

The 0.9% benzyl alcohol concentration is studied to inhibit bacterial proliferation by disrupting microbial membrane integrity, thereby maintaining sterility in multi-withdrawal vials across the post-puncture stability window.

Lyophilate solubilisationaqueous reconstitution matrix

The sterile aqueous base provides a physiologically compatible ionic environment for dissolving lyophilized peptide reference materials, preserving structural integrity of reconstituted compounds for in vitro assay use.

Preservative stabilityextended vial integrity

The preservative system is formulated to remain chemically stable and effective for 28 days post-puncture, supporting repeated aliquot withdrawal without compromising the sterility or composition of the bulk solution.

For research use only. Mechanisms described reflect published preclinical and clinical literature.

The process

How every batch is verified

01
Synthesized
Produced under controlled manufacturing with documented, repeatable processes.
02
HPLC purity
An independent lab reports the exact purity of every lot — a number, never a 'passes'.
03
Mass-spec identity
Molecular weight confirms the exact sequence is what the label says.
04
COA published
The certificate is posted to the open library, by lot, before the vial ships.
