Benzyl Alcohol 0.9% (Bacteriostatic)
Source-Reviewed Research Dossier
This catalog item is a water-based research solution described as containing 0.9% benzyl alcohol. Benzyl alcohol can limit microbial growth, but can also affect the material dissolved in it. A study of a dried protein found more clumping after reconstitution with benzyl alcohol under the tested conditions. That does not mean every peptide reacts the same way. Check the actual composition, acidity, container and batch documentation, and assess compatibility with the target material. The product name alone does not establish sterility or stability.

Reported research findings
What published studies report about Benzyl Alcohol 0.9% (Bacteriostatic)
Reported outcomes are paired with their experimental model and evidence boundary.
The preservative concentration is 9 mg/mL
The referenced Bacteriostatic Water label lists benzyl alcohol at 0.9% (9 mg/mL).
The full formulation and container must still match the catalog specification.
Read the primary studyBenzyl alcohol can promote aggregation
A recombinant-protein study found benzyl-alcohol-induced aggregation depended on the retained structure of the lyophilized formulation.
PMID 15614819 supports the need for molecule-specific compatibility testing.

Benzyl Alcohol 0.9% (Bacteriostatic) questions
Concise answers for researchers comparing identity, evidence and catalog variants.
What effects are studied for Benzyl Alcohol 0.9% (Bacteriostatic)?
It is a preserved water-based liquid used when a laboratory solution needs to resist microbial growth during repeated handling. The 0.9% figure describes benzyl alcohol concentration, not a complete formulation. Its practical interest is the trade-off: the preservative protects the liquid, but it can also change how sensitive dissolved materials behave, so each use has to be tested.
How should the Benzyl Alcohol 0.9% (Bacteriostatic) research findings be understood?
A catalog entry fixes a name and concentration, not every detail that changes behavior. The liquid it is dissolved in, pH, container material, air space, sterility statement and lot specification can all matter. Researchers should confirm those details instead of treating 0.9% as the whole definition, and should not assume a laboratory supply matches a finished medicine.
What evidence is available for Benzyl Alcohol 0.9% (Bacteriostatic)?
DailyMed establishes the common 9 mg/mL formulation, and published protein-formulation work documents aggregation risk under some conditions.
Does the cited research validate this catalog material?
No. The cited records describe their own intervention, formulation, model and controls. They do not verify the identity, purity, sterility, safety or efficacy of a catalog lot.
Which quality documents can be requested?
A lot-specific COA, product specification sheet and analytical method summary can be requested where applicable.
How should Benzyl Alcohol 0.9% (Bacteriostatic) be stored?
Store at 2-8 °C. Do not freeze. Protect from light. Confirm the applicable storage statement on the product-specific specification and lot documentation.
