Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
Based on the above results, HCFO-1233yd(Z) showed no corrosion to rabbit eye and it was judged as "Mildly irritating" and regarded as ''Not classified" according to the GHS classification under the conditions of this study.
Executive summary:

The eye irritation/corrosion potential of the HCFO-1233yd(Z) (the test substance) was examined in Japanese White rabbits (lla:JW, female). The test substance (0.1 mL) was applied to the left eye of one (initial test) and two animals ( confirmatory test), and the eye reactions were observed for the longest 96 hours after application and the eye corrosion/irritation potential was evaluated. The results are summarised as follows:

There were no corrosive changes in any animal during the observation period. Conjunctival redness, chemosis and discharge were observed in 3/3 or 2/3 animals at 1 hour after application. Eye irritation reactions were alleviated with the passage of time and all changes disappeared by 96 hours after application. The maximum mean total score (MMTS) was recorded at 1 hour after application and the value was 7.3. In the evaluation by the Kay and Calandra classification, the value of mean total score at 48 hours after application (MTS 48) was 0.7 and higher than 0, thus the test substance was classified as "Mildly irritating". In the evaluation of irritation by the GHS classification criteria, the test substance was regarded as ''Not classified" since there were no animals that showed positive response for corneal opacity (degree), iritis, conjunctival redness or chemosis. There were no abnormalities in clinical signs or body weight of any animal.

Based on the above results, HCFO-1233yd(Z) showed no corrosion to rabbit eye and it was judged as "Mildly irritating" and regarded as ''Not classified" according to the GHS classification under the conditions of this study.
