Concentration accuracy is harder than it looks The 0.9% benzyl alcohol target is a narrow window with consequences on both sides: Too little benzyl alcohol (below ~0.5%) and the bacteriostatic effect weakens significantly, allowing bacterial growth in the multi-dose vial during the 28-day use window Too much benzyl alcohol (above ~2%) and tissue toxicity becomes a concern published research has documented injection site irritation, tissue damage, and in extreme concentrations, systemic toxicity from benzyl alcohol exposure For a 30 mL batch, the target benzyl alcohol volume is 0.27 mL roughly five drops from a standard dropper
