Test animals / tissue source

Species:

rabbit

Strain:

New Zealand White

Details on test animals or tissues and environmental conditions:

Male and female white New Zealand rabbits weight between 3.7 and 6.0 kg each. Animals were marked with a 5 digit number and held in steel cages. They were acclimated for 14 days prior to testing. Standard rabbit diet and water was provided ad libitum. Room temperature was held at 20 degrees C +/- 1 degree C, humidity at 60 +/- 5%, with a 12/12 hour light/dark cycle.

Test system

Vehicle:

unchanged (no vehicle)

Controls:

yes, concurrent no treatment

Amount / concentration applied:

0.1 mL

Duration of treatment / exposure:

Single treatment that was not washed out.

Observation period (in vivo):

1, 24, 48, and 72 hours and at 6 days after application.

Number of animals or in vitro replicates:

6 (3 male, 3 female)

Details on study design:

Treatment was to the right eye with lower lid removed. The left eye was untreated and served as the control. The eyes were not washed out during the test. Observations were made at 1, 24, 48, and 72 hours and at 6 days after application.

Results and discussion

In vivo

Results

Irritation parameter:

overall irritation score

Basis:

mean

Time point:

other: 1, 24, 48, and 72 hrs and 6 days

Score:

46.9

Reversibility:

not fully reversible within: 6 days

Remarks on result:

other: moderately irritating

Irritant / corrosive response data:

Results indicated a moderate irritancy, but because of the intensity of the necrosis formation, the study was stopped at day 6.

Any other information on results incl. tables

Treatment was to the right eye with lower lid removed. The left eye was untreated. The eyes were not washed out duringthe test. Observations were made at 1, 24, 48, and 72 hours and at 6 days after application. The total irritation index was 46.9.

Applicant's summary and conclusion

Interpretation of results:

other: moderately irritating

Remarks:

Criteria used for interpretation of results: EU

Conclusions:

Result: moderately irritating at 0.1 mL.

Executive summary:

The eyes of six rabbits were treated with the test substance and observed for six days. Results indicate that the substance was moderately irritating but because of the intensity of the necrosis formation the study was stopped at day 6.
