- Specific details on test material used for the study:
- For testing liquids, a dose of 0.1 ml will be used. In testing solids, pastes and particulate substances, the amount used should have a volume of 0.1 ml , or a weight of not more than 100 mg. If the test material is solid or granular
it should be ground to a fine dust .
Test animals / tissue source
- Species:
- rabbit
- Strain:
- New Zealand White
- Details on test animals or tissues and environmental conditions:
- 0.1g of test material was added to one eye of each test animal.
Test system
- Vehicle:
- not specified
- Controls:
- yes
- not specified
- Amount / concentration applied:
- 0.1g
- Duration of treatment / exposure:
- 24 hours
- Observation period (in vivo):
- 21 days
- Duration of post- treatment incubation (in vitro):
- N/A
- Number of animals or in vitro replicates:
- 6
- Details on study design:
- The eyes will be examined and graded for ocular reactions at approximately 1 hour , 24 , 48 and 72 hours, after application using the Draize method reproduced in Appendix I . Except for the 1 hour scoring and only if corneal opacity scores of 2 or less are noted , the eyes may be scored again for corneal opacity intensity and area using fluorescein. Following the 24-hour scoring all eyes may be rinsed with copious amounts ( at least 200 ml) of physiological saline only if necessary.
Results and discussion
In vitro
Results
- Irritation parameter:
- fluorescein retention score
- Value:
- >= 1 - <= 5
- Vehicle controls validity:
- not specified
- Negative controls validity:
- not specified
- Positive controls validity:
- not specified
- Other effects / acceptance of results:
The test material produced corneal opacity persisting through day 21, iritis persisting through day 10 and conjunctiva irritation persisting through day 21 when applied to the eyes of six New Zealand White rabbits. In addition,
corneal vascularization became apparent at day 7 and persisted through day 21

Applicant's summary and conclusion
- Interpretation of results:
- Category 1 (irreversible effects on the eye) based on GHS criteria
- Conclusions:
- The test material produced corneal opacity persisting through day 21, iritis persisting through day 10 and conjunctiva irritation persisting through day 21 when applied to the eyes of six New Zealand White rabbits. In addition,
corneal vascularization became apparent at day 7 and persisted through day 21.
Maximum total irritation scores in individual animals ranged from 61 to 83. - Executive summary:
SUMMARY/CONCLUSIONS
The primary ocular irritancy was evaluated in compliance with the conditions specified in the regulation for the enforcement of the Federal Insecticide, Fungicide, and Rodenticide Act (40 CFR), the Toxic Substances Control Act (40 CFR), and the OECD Guidelines.
