Irritant / corrosive response data:
Irritant effects on conjunctiva (redness) were minimal at 1 hour in all animals and were fully reversed at 72h in all animals. There were no effects on the cornea and the iris at any time point. Chemosis was not observed at any time point in all animals.
It can be concluded that DV 98-25 would not be classified as eye irritant.
Other effects:
No data

Applicant's summary and conclusion

Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
under the test conditions, DV 98-25 is not classified as eye irritant according to the criteria of Annex VI of the Directive 67/548/EEC and the CLP Regulation 1272/2008.
Executive summary:

The eye irritant effect of DV 98-25 was investigated according to the OECD Guideline No. 405 (1987) and EEC B.5 method (1992) and in compliance with Good Laboratory Practice.

Three female albino rabbits were exposed to 0.1 mL of the test article in the left eye. The eyes were examined and the changes were graded according to a numerical scale 1, 24, 48 and 72 hours after dosing.

Minimal conjunctival irritation (redness) was observed in the three rabbits 1 hour after dosing. During the rest of the observation period no abnormalities were observed for two animals while redness (score 1) was still observed up to 48 h in the third animal.

DV 98 -25 is not considered as irritating to the eyes according to Annex VI of the Directive 67/548/EEC and CLP Regulation 1272/2008.
