- 760-67-8
- Molecular formula:
- C8H15ClO

Constituent 1
Test animals / tissue source
- Species:
- rabbit
- Strain:
- not specified
Test system
- Vehicle:
- unchanged (no vehicle)
- Controls:
- other: The untreated left eye served as a control.
- Amount / concentration applied:
- 100 µL
- Duration of treatment / exposure:
- In 3/9 animals the treated eyes were washed out after 30 sec; in all other animals, washing was not performed
- Observation period (in vivo):
- 21 d
- Number of animals or in vitro replicates:
- 9
- Details on study design:
- A test with fluorescein showed that the eyes were normal prior to testing. Test material (0.1 ml) was placed into the conjunctival sac of the right eye of each of 9 animals. The lids were held together for one second. Three of the nine treated eyes were each washed with room temperature deionized water for 1 minute, 30 seconds after treatment.
The treated eyes were examined for irritation 1, 24, 48 hours and 4, 7, 10, 14, 17 and 21 days after treatment. The corneas were re-examined after treatment with 0.2% fluorescein sodium ophthalmic solution after the 24 hour observation time. If staining was observed, staining was repeated after each subsequent evaluation time until staining no longer occurred.
