Test system
- Vehicle:
- unchanged (no vehicle)
- Controls:
- other: The untreated eye served as the control.
- Amount / concentration applied:
- 100 mg of the test substance was allowed to “fall on the averted lower lid of one eye.” The eyelids were held together for at least one second to prevent loss of the test material.
- Duration of treatment / exposure:
- The eyes were not washed following instillation. As no examination was conducted at 1 hour after instillation, it is unclear whether the test material was removed from the eye by physiological mechanisms at that time
- Observation period (in vivo):
- Animals were examined 24, 48, 72 hours and 7 days after instillation.
Initial pain reaction was not reported
Clinical signs of toxicity during the study were not reported.
Ocular reactions, read using a binocular magnifying glass, of the individual animals were recorded at each observation time
“The diagnosis of corneal damage is confirmed, if necessary, by staining the eyes of the animals with fluorescein-impregnated papers.” [As no animals exhibited signs of cornea damage, this technique, most probably, was not applied] - Number of animals or in vitro replicates:
- 6 animals
- Details on study design:
- SCORING SYSTEM: The FDA scoring scale was used

- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: other: According to the FDA standards the test material AK 43/79 is not considered an eye irritating agent.
- Conclusions:
- No eye irritation/ corrosion effects were observed. According to the FDA standards applied, aluminium oxide is not considered an eye irritant.
- Executive summary:
An eye irritation study of the test item Aluminium oxide (coded AK 43/79) was performed inWhite albino rabbits. Six animals were used in this experiment. The irritation effects of the test item were evaluated according to theFDA criteria. 100 mg of the test item was administered as a single dose. The test item was placed into the conjunctival sac of the eye. The untreated eye served as control. The eyes of the test animals were not washed after the application of the test item. The eyes were examined 24, 48, 72 hours and 7 days after the application. No examination was conducted 1 hour after the application. Initial Pain Reaction was not reported.
At 24 hours after instillation a conjunctival redness (score 1) and chemosis (score 1) was observed in all animals. No cornea or iris lesions in any animal. At 48 hours after instillation,conjunctival redness (score 1) was observed in all animals and chemosis (score 1) in 4 animals. No animals showed signs of cornea or iris lesions. At 72 hours after instillation,conjunctival redness (score 1) was observed in all animals. No animal showed signs of chemosis, cornea or iris lesions. At 7 days after instillation,conjunctival redness (score 1) was observed in one animal, and there were no signs of chemosis, cornea or iris lesions in any animal.
