Applicant's summary and conclusion

Interpretation of results:
Category 1C (corrosive) based on GHS criteria
Executive summary:

In a GLP-compliant OECD 435 Guideline study, the mean time for the test substance to penetrate the biobarrier was 32.18 minutes (+/- 0.17) and was therefore determined to be corrosive to skin and classified as Category 1C (corrosive) based on GHS criteria.
