Résumé
In vitro absorption through human skin is a critical component in the safety assessment of chemicals, crop protection products, consumer healthcare products and cosmetics. A barrier integrity assay is used to identify skin samples which are potentially damaged. A retrospective analysis of 9978 electrical resistance (ER) measurements generated in a single laboratory (DTL) over a 15-year period was performed. Skin absorption experiments were performed using two model penetrants, testosterone and sucrose, utilising no ER acceptance criteria, and the results assessed. Using a barrier integrity test, to remove potentially damaged samples, was offset against one that can be used to remove intact skin samples with a poorer barrier function (i.e. false positives). The previously identified barrier integrity limit (10 kΩ for a 2.54 cm
