Water with 0.9 per cent benzyl alcohol has an osmolality near 80 milliosmoles per kilogram, far below the roughly 290 of body fluids and of normal saline. It is hypotonic. Bacteriostatic saline is isotonic. For a peptide in solution, osmolality is not directly relevant; for a cell exposed to the solution, it is decisive.
The preservative contributes almost all of the osmolality of bacteriostatic water.
Bacteriostatic water has essentially no ionic strength and no buffer. Saline has high ionic strength and no buffer. Phosphate-buffered saline has both. Ionic strength screens charges and affects peptide solubility and metal binding; buffering fixes pH. A peptide dissolved in each of the three is in a different chemical environment.
The pages on solubility and buffering elsewhere on this site describe those effects.
Lyophilised peptides are characterised and their solubility reported in water, and the preserved form is the one that suits a multiple-entry vial. That is a statement about which product is in the box, not a recommendation about any other.
Bacteriostatic water is supplied by REVIVE LAB UAE as a diluent for lyophilised research peptides, for laboratory research use only. It is not for human or veterinary use, and no dosing, administration or protocol guidance is provided.
