Test animals / tissue source
- Species:
- rabbit
- Strain:
- New Zealand White
- Details on test animals or tissues and environmental conditions:
- Three New Zealand White rabbits were supplied by David Percival Ltd, Moston, Sandbach, Cheshire, UK. At the start of the study the animals weighed 2.71 to 3.09 kg and were twelve to sixteen weeks old. After an acclimatisation period of at least five days each animal was given a number unique within the study which was written with a black indelible marker-pen on the inner surface of the ear and on the cage label.
The animals were individually housed in suspended metal cages. Free access to mains drinking water and food (STANRAB SQC Rabbit Diet) was allowed throughout the study. The diet and drinking water were considered not to contain any contaminant of a level that might have affected the purpose or integrity of the study.
The temperature and relative humidity were set to achieve limits of 17 to 23°C and 30 to 70% respectively. Any occasional deviations from these targets were considered not to have affected the purpose or integrity of the study. The rate of air exchange was at least fifteen changes per hour and the lighting was controlled by a time switch to give twelve hours continuous light (06:00 to 18:00) and twelve hours darkness.
Test system
- Vehicle:
- unchanged (no vehicle)
- Controls:
- yes, concurrent negative control
- Amount / concentration applied:
- 0.1 mL of test item, which weighed approximately 20 mg.
- Duration of treatment / exposure:
- Single application.
- Observation period (in vivo):
- 72 hours
- Number of animals or in vitro replicates:
- 3 rabbits
- Details on study design:
- Immediately before the start of the test, both eyes of the provisionally selected test rabbits were examined for evidence of ocular irritation or defect with the aid of a light source from a standard ophthalmoscope. Only animals free of ocular damage were used.
Initially, a single rabbit was treated. A volume of 0.1ml of the test material, which was found to weigh approximately 20 mg (as measured by gently compacting the required volume into an adapted syringe) was placed into the conjunctival sac of the right eye, formed by gently pulling the lower lid away from the eyeball. The upper and lower eyelids were held together for about one second immediately after treatment, to prevent loss of the test material, and then released.
The left eye remained untreated and was used for control purposes.
After consideration of the ocular responses produced in the first treated animal, two additional animals were treated.
Assessment of ocular damage/irritation was made approximately 1 hour and 24, 48 and 72 hours following treatment, according to the numerical evaluation (Draize)
Any other ocular effects were also noted. Examination of the eye was facilitated by the use of the light source from a standard ophthalmoscope.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test item did not produce mean scores following grading at 24, 48 and 72 hours for corneal opacity ≥ 1, iritis ≥ 1, conjunctival redness ≥ 2 or conjunctival oedema (chemosis) ≥ 2, as such it does not meet the requirements to be classified as a irritant to the rabbit eye according to GHS.
- Executive summary:
Introduction.
The study was performed to assess the irritancy potential of the test material to the eye of the New Zealand White rabbit. The method was designed to meet the requirements of the following:
- OECD Guidelines for the Testing of Chemicals No. 405 “ Acute Eye Irritation/Corrosion" (adopted 24 February 1987)
- Commission Directive 92/69/EEC Method B5 Acute Toxicity (Eye Irritation)
Result
A single application of the test material to the non-irrigated eye of three rabbits produced minimal conjunctival irritation. No ocular effects were noted at the 48-hour observation.
Conclusion
The test item did not produce mean scores following grading at 24, 48 and 72 hours for corneal opacity ≥ 1, iritis ≥ 1, conjunctival redness ≥ 2 or conjunctival oedema (chemosis) ≥ 2, as such it does not meet the requirements to be classified as a irritant to the rabbit eye according to GHS.
