Test material
Reference
- Name:
- Unnamed
- Type:
- Constituent
- Details on test material:
- - Physical state: Pale yellow powder
- Analytical purity: 99.04%
- Lot/batch No.: 5/87; Indent 9200/9622
- Storage condition of test material: Following its arrival in Compound Control this test substance was stored in the dark at ambient temperature.
- Stability: Infra-red spectra of the test substance were taken. There were no significant differences between the spectra and so, on this basis, the test substance was judged to have been stable for the duration of this study.
Test animals / tissue source
- Species:
- rabbit
- Strain:
- New Zealand White
- Details on test animals or tissues and environmental conditions:
- TEST ANIMALS

- Acclimation period: At least, two weeks.
ENVIRONMENTAL CONDITIONS
- Temperature (°C): 16-19 ºC
- Humidity (%): Not documented.
- Air changes (per hr): Not documented.
- Photoperiod (hrs dark / hrs light): Lighting was automatically switched on for the day (06.00 to 18.00 hours GMT) and off for the night (18.00 to 06.00 hours GMT).
Test system
- Vehicle:
- unchanged (no vehicle)
- Controls:
- not required
- Amount / concentration applied:
- TEST MATERIAL
- Amount(s) applied (volume or weight with unit): 25 mg - Duration of treatment / exposure:
- The eyes were not washed.
- Observation period (in vivo):
- A visual assessment of eye irritancy was made at 1, 4, 24, 48 and 72 hours and 7 days after instillation.
- Number of animals or in vitro replicates:
- Three per sex
- Details on study design:
- SCORING SYSTEM: Irritancy was scored for the cornea, iris and conjunctivae using the standard scores included in the study report.
TOOL USED TO ASSESS SCORE: At 24 hours and in the event of any corneal damage visualization was aided by the instillation of one drop of 2% fluorescein solution.

- Irritant / corrosive response data:
- The instillation of the test substance powder into the conjunctival sac of one eye of each of six rabbits resulted in slight initial pain. The only occular effect was slight conjunctival redness in all rabbits within 1 hour of dosing which had cleared by 24 hours.

Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- In the rabbit eye irritancy test, the test material caused slight conjunctival redness within 1 hour of dosing which had cleared by 24 hours. The test material is therefore not an eye irritant in rabbits.
- Executive summary:
The test material (25 mg) was applied to the eyes of six New Zealand White rabbits (3 per sex). A visual assessment of eye irritancy was made at 1, 4, 24, 48 and 72 hours and 7 days after instillation. The test material caused slight conjunctival redness within 1 hour of dosing which had cleared by 24 hours.
