Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The Reaction mass of TFSK/TFAK is not iritating to eyes.
Executive summary:

An eye irritation study was performed according to OECD TG 405 and under GLP conditions. An instillation of 0.1 ml of the test item in one eye of 3 rabbits was performed. One eye remained untreated and served as a control. No irreversible effects were noted. Based on the results above, the test material is not classified for eye irritation.
