Is benzyl alcohol at 0.9% enough to matter for peptide stability?

My setup is a refrigerator with a logger and a small work area I wipe down, nothing more.

This is one of those things that everyone repeats and nobody derives.

This matters practically, not just academically, because it changes what I would do next.

Is the standard explanation correct, and if so, what is the evidence for it?
