In three participating laboratories, photochemical reactivities of 42 coded chemicals and two standard controls were assessed by reactive oxygen species (ROS) assay for photosafety evaluation. Outcomes from the validation study were indicative of satisfactory transferability, intra- and inter-laboratory variability, and predictive capacity of the ROS assay. Thus, results from the present validation study provided sufficient support for the ROS assay as an alternative method for photosafety assessment.
