BRIEFING
〈660〉 Containers—Glass. This proposal is based on the version of the chapter official as of October 1, 2023. The previous proposal, published in PF 50(5), has been canceled. The Packaging and Distribution Expert Committee is proposing this new version to enhance the evaluation and standards for glass packaging systems used in pharmaceuticals. These changes include the addition of new glass materials; the removal and replacement of outdated tests; revisions to existing methodologies to ensure better safety, efficacy, and performance of glass packaging in pharmaceutical applications; and a new title that better reflects the chapter content. The key changes being proposed are as follows:
-
Change the chapter title to "Glass Containers and Their Composition" to better reflect the revised content.
-
Introduce two new glass materials—aluminosilicate glass and quartz glass—to provide more options with varying properties for different pharmaceutical applications.
-
Replace the Glass Grains Test with a new identification test (4.1.1 Elemental composition by wavelength dispersive X-ray fluorescence) based on WDXRF. This modern method enhances the accuracy of glass identification and characterization.
-
Delete the Surface Etching Test in order to streamline the testing process and remove redundancies.
-
Revise the Determination of Inner Surface Hydrolytic Resistance test by incorporating guidance on the application of autoclave instructions, based on new studies, to ensure precise and reliable testing.
-
Add a new extractable arsenic test (4.4 Extractable Arsenic) that uses inductively coupled plasma (ICP) technology to provide more sensitive and accurate measurement of arsenic levels.
-
Revise the Spectral Transmission for Colored Glass Containers test by incorporating data from both borosilicate and soda–lime–silica colored glass to refine the evaluation of light protection capabilities.
The supporting general information chapter Evaluation of the Inner Surface Durability of Glass Containers 〈1660〉 is also being revised and is published in this issue of PF.
Additionally, minor editorial changes have been made to update the chapter to current USP style.
