Bacteriostatic Water:
Type: Sterile, non-pyrogenic water containing a bacteriostatic preservative.
Composition:
Sterile Water, USP Benzyl Alcohol 0.9% (as preservative).
pH range: Typically 4.5–7.0
Function / Use:
Used as a diluent or solvent for reconstituting lyophilized drugs or peptides for research and laboratory purposes.
The bacteriostatic agent (benzyl alcohol) inhibits microbial growth, allowing multiple withdrawals from a single vial (unlike sterile water, which is single-use).
Synergy potential: Serves as a stable vehicle for peptide reconstitution, maintaining sterility during multiple-use conditions in controlled research settings.
