Overview
BAC Water — a bacteriostatic diluent — sits in the "Minimal evidence" tier of this catalog. There is little or no formal study of this compound. Claims rest on anecdote, theory, or very early-stage work; risk data are absent by definition.
Sterile water for injection containing 0.9% benzyl alcohol as a preservative, used as a reconstitution diluent. It is a regulated pharmaceutical component, not a therapeutic.
Mechanism of Action
Benzyl alcohol suppresses microbial growth, allowing multi-use of a vial within its labeled discard window — distinct from single-use sterile water.
Research and Evidence
Not applicable as a therapeutic; quality and sterility standards are the relevant "evidence."
Safety and Side Effects
Preserved diluent must not be used in neonates (benzyl alcohol toxicity) or intrathecally. Unregulated "bac water" of unverifiable sterility undermines any downstream use.
Frequently Asked Questions
What is the evidence tier of BAC Water?
BAC Water is graded "Minimal evidence" on this site. There is little or no formal study of this compound. Claims rest on anecdote, theory, or very early-stage work; risk data are absent by definition.
