Overview

Bacteriostatic Water (BAC Water) is sterile water for injection with 0.9% benzyl alcohol, conferring bacteriostatic activity to prevent microbial growth during multiple withdrawals. In peptide laboratories, BAC Water helps maintain solution integrity during in-vitro reconstitution of lyophilized compounds. This 3 mL presentation supports precise dosing in small-volume peptide studies.

How It Works (Mechanism of Preservation)

  • Benzyl Alcohol Action: Disrupts microbial cell membranes and protein conformation, exerting bacteriostatic effects against common lab contaminants.[1–3]
  • Multiple Withdrawals: The preservative supports repeated vial access under aseptic technique (unlike preservative-free sterile water, which is single-use).[4]
  • Compatibility: Demonstrated chemical compatibility with many peptides under controlled conditions; however, researchers should validate stability for each specific compound.[5–7]

Research Areas & Applications

  1. Peptide Reconstitution & Stability – BAC Water is commonly used to dissolve lyophilized peptides for in-vitro assays, allowing short-term storage after reconstitution.[8–10]
  2. Aseptic Sampling Techniques – Supports multiple withdrawals for ongoing experiments while limiting bacterial proliferation.[11–12]
  3. Formulation & Solubility Studies – Investigators assess peptide solubility profiles, pH tolerance, and benzyl alcohol interactions.[13–14]
  4. Microbial Preservation Efficacy – Benzyl alcohol’s antimicrobial effect has been benchmarked against USP standards for multi-dose containers.[2, 15]
  5. Stability Under Cold Storage – Research shows that benzyl alcohol–containing solutions maintain sterility but may impact long-term peptide integrity; proper aliquoting is advised.[6, 16]

2.1 Preservative Efficacy & Standards

Benzyl alcohol at 0.9% meets pharmacopeial criteria for antimicrobial effectiveness in multi-dose parenterals.[1–3] Studies comparing preservative systems confirm benzyl alcohol’s broad utility across pH ranges typical of peptide solutions.[15, 17]

2.2 Compatibility with Peptide Reconstitution

Investigators report that BAC Water maintains peptide solubility and sterility for short-term in-vitro work; however, some peptides exhibit reduced stability in alcohol-containing diluents, necessitating pilot testing and aliquoting strategies to avoid multiple freeze–thaw cycles.[5–7, 18]

2.3 Sterility, Pyrogen Control & Aseptic Handling

USP and FDA guidelines emphasize sterile preparation, pyrogen testing, and aseptic technique. Even with benzyl alcohol, improper handling, needle reuse, or prolonged storage beyond recommended limits increases contamination risk.[4, 11, 19]

2.4 Storage & Stability Considerations

While benzyl alcohol extends usable life, most labs follow a 28-day beyond-use guideline post-first puncture, with refrigeration to slow degradation and microbial growth. Peptide stability data suggest aliquoting into sterile vials to minimize repeated vial entries.[6, 16, 20]

2.5 Safety Notes in Research Context

Benzyl alcohol has known toxicity in neonates and is strictly contraindicated in human neonatal applications (“gasping syndrome”). In research, this underscores the importance of research-only labeling and clear delineation from clinical or veterinary use.[21–23]

  • Unopened Vial (Lyophilized-free, Liquid Form): Store at 20–25 °C (68–77 °F), protected from light.
  • After First Puncture: Refrigerate at 2–8 °C (36–46 °F); discard after 28 days or sooner if turbidity/particulates appear.
  • Aliquoting: For prolonged in-vitro studies, aseptically transfer to sterile aliquots to minimize repeated vial entries.
  • Avoid Freezing: Freezing can compromise stopper integrity and preservative distribution.
