Applicant's summary and conclusion

Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The overall mean score for conjunctival redness was 0.3, and for chemosis was 0.2. All eyes were normal 72 hours following instillation of the test substance.
Executive summary:

C5 Produkt (CAS 92128 -68 -2) was non irritating to the rabbit eye and does not warrant classification under DPD or GHS/CLP.
