Test animals / tissue source
- Species:
- rabbit
- Strain:
- New Zealand White
- Details on test animals or tissues and environmental conditions:
- TEST ANIMALS
- Stock supply of healthy adult rabbits
- Number and Sex: 3 females
- Age on day of dosing (Day 1): 39 or 40 weeks
- Weight prior to dosing (Day 1): Minimum 4.04 kg, maximum 4.63 kg
- Housing: Individual housing in plastic cages with peforated floor
- Environmental enrichment: Small soft white untreated wood blocks
- Diet : Standard laboratory rabbit diet (125 g/animal/day). In addition, dietary supplement of hay
replaced by a supplement of wholemeal bread as from 2 days prior to dose instillation.
- Water: Drinking water, ad libitum
- Acclimation period: 20 to 21 weeks prior to study start under laboratory conditions.
Routine analysis of the batch of diet used for nutrients, possible contaminants and microorganisms and of the drinking water were conducted or available at the testing facility.
ENVIRONMENTAL CONDITIONS
Air conditioned animal room set at:
- Temperature (°C): 18 ± 2°C (as an exception on a single day up to 28°C) *
- Relative Humidity (%): 40 to 70% (as an exception on a single day up to 79%) *
- Photoperiod: 12 hrs artificial light per 24 hrs
* The excursion from the target limits of animal room temperature and relative humidity on a single day was transient and had no impact on the wellbeing of the animals, and thus was considered to have had no impact on the study results.
Test system
- Vehicle:
- unchanged (no vehicle)
- Controls:
- not required
- Amount / concentration applied:
- 0.1 mL (weighing ca. 98 mg) of the test material was instilled into the conjunctival sac of one eye per rabbit (right eye).
Immediately after instillation upper and lower eyelids were held together for about 1 second to prevent loss of test material.
The contralateral eye (left eye) remained untreated to serve as a control. - Duration of treatment / exposure:
- Eyes were not rinsed after treatment with the test substance. Consequently the treatment/exposure period was equivalent to the entire observation period following instillation, which was 72 hours, or lasted until removal of the test material by physiological mechanisms, whichever happened sooner.
- Observation period (in vivo):
- 72 hours post instillation
- Number of animals or in vitro replicates:
- 3
- Details on study design:
- EYE EVALUATION:
Before treatment start both eyes of each animal were investigated to ensure that there was no pre-existing corneal damage, iridial inflammation or conjunctival irritation.
One animal (the sentinel) was initially treated and in the absence of a severe effect the remaining two animals were committed to the study.
Eyes were evaluated in all animals at approximately 1, 24, 48 and 72 hours after test substance instillation adopting the numerical scoring system listed in Table 1 in the field below. Grades attained at 24, 48 and 72 hours after instillation were included in the mean gradings of ocular lesions and used for evaluation of the necessity of eye irritation/corrosion classification. Additional checks of the animals at appropriate intervals ensured that no severe injury passed unnoticed.
Equipment used for eye evaluation: Ophthalmoscope or pencil beam torch

- Irritant / corrosive response data:
- Corneal and iridic lesions, chemosis and conjunctival discharge were not evident throughout the study. Conjunctival redness, grade 1 (injection of conjunctival blood vessels), was seen in all treated eyes at 1 and/or 24 hours after instillation having completely disappeared in two animals by 24 hours after instillation and in the other animal by 48 hours after instillation. Throughout the study no other signs of ocular irritation were evident.
- Other effects:
- Observation of the animals for defined behavioural criteria led to the conclusion that instillation of the test substance induced practically no or a slight initial pain response. Any other signs, of systemic toxicity or ill health were not evident.
Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The outcome of the present study does not necessitate any labelling regarding eye irritation according to EU classification rules [DIRECTIVE 67/548/EEC and REGULATION (EC) 1272/2008]. The minor findings noted at 1 and/or 24 hours post instillation are within the category “not irritating to eyes”. They were fully reversible.
