What researchers study
Sterile water with a bacteriostatic preservative, conventionally benzyl alcohol, which limits microbial growth in multi-entry vials; the exact preservative level of this listing is to be confirmed by Novatide. In the laboratory it serves as a diluent for lyophilised peptides.
Research areas
- Dissolving water-soluble lyophilised peptides
- Multi-entry vial handling in assay preparation
- Preservative-containing diluent comparisons
- Stability studies of reconstituted peptide solutions
Reported findings
Summaries of published results. Each one is tagged with the type of study behind it. They describe research outcomes and are not claims about any product. Why study type matters.
- product label
A US product label describes bacteriostatic water as sterile water with benzyl alcohol as preservative at 0.9% (9 mg/mL) or 1.1% (11 mg/mL)
- product label
The label states it is only for diluting or dissolving drugs and not for neonates, as benzyl alcohol has been linked to toxicity
Studied alongside
Compounds that appear together in research because their mechanisms complement each other, or as comparators. The reasons given are research reasoning, not recommendations for use.
