Dye ingress testing evaluates container closure integrity by exposing sealed packaging to a colored dye under controlled conditions. When leaks are present, the dye penetrates into the package, visually revealing defects. This straightforward method provides immediate, clear evidence of leaks and is widely used in pharmaceutical quality assurance. While not as sensitive as deterministic technologies, dye ingress complements other CCIT methods and aids in comparative testing, design validation, and QA processes. Learn how dye ingress supports comprehensive packaging integrity evaluation in pharma environments.
