OptiSafe Validation Study

NICEATM coordinated a multi-laboratory validation study to determine the reliability and relevance of the OptiSafe test method. In this method, a test substance is applied to a semi-permeable membrane to assess the substance’s potential to cause eye irritation.

The study was completed in 2018 and a report on the study has been published (Choksi et al. 2020). The study demonstrated that the OptiSafe method is useful for identifying non-surfactant substances that do not require classification for ocular irritancy and thus can reduce the use of animals for this type of testing.
