- Irritant / corrosive response data:
- One and 24 hours after application the conjuntivae of the animals showed a diffuse beefly red colour and obvious swellings up to swellings with lids about half closed. The iris was sporadically reddned. One hour after application clear, colourless eye discharge was noted. 24 hours after application the cornea showed diffuse opacity areas. 48 hours after application definitely injected blood vessels were observed in two animals. 72 hours after application all signs of irritation were reversible.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Based on the testing for primary eye irritation in the rabbit, the substance is slightly irritating to eye. But the effect does not result in a classification of the test item.
- Executive summary:
The test item was subject to an Acute Eye Irritation/Corrosion Test in the rabbit according to OECD TG 405. For this purpose 100 mg of test material were instilled in the left conjunctival sac of three New Zealand white rabbits. 24 hours after application the treated eyes were washed out thoroghtly with isotonic saline at 30°C. The eyes were examined 1, 24, 48, and 72 hours after application of the test item. One and 24 hours after application the conjuntivae of the animals showed a diffuse beefly red colour and obvious swellings up to swellings with lids about half closed. The iris was sporadically reddned. One hour after application clear, colourless eye discharge was noted. 24 hours after application the cornea showed diffuse opacity areas. 48 hours after application definitely injected blood vessels were observed in two animals. 72 hours after application all signs of irritation were reversible.
Based on the testing for primary eye irritation in the rabbit, the substance is slightly irritating to eye. But the effect does not result in a classification of the test item.
