Notes

Content audit 9 Sep 2026: size all sizes → #42219 10ml. Certificate prints: prints compound "Bacteriostatic Water", lot "1670", lab id "V260130-10 004", content 0.82% (Benzyl Alcohol Content result, no
Content audit 9 Sep 2026, second pass: size 42219 → all sizes. Back to every size. The certificate tests a 10 mL vial of lot 1670 and staff filed it under the 30 mL product, whose only buyable size is 30 mL; pinning it to the hidden 10 mL size left the 30 mL size with no certificate. Whether the 30 mL bottle is filled from lot 1670 is the owner's call.

A chapter number names the method or limit a result follows; it does not describe the product. Chapters below 1000 are procedures or limits; 1000-series chapters are informational. USP <905> is the compendial test for between-unit uniformity: it assays 10 units, so a 3-unit certificate cannot yield its acceptance value — the content row is a house check with <905> named as the reference only.
