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): 23 - 34 weeks
- Weight prior to dosing (Day 1): Minimum 4.09 kg, maximum 4.82 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: 7 or 8 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
- Relative Humidity (%): 40 to 70%
- Photoperiod: 12 hrs artificial light per 24 hrs
Test system
- Vehicle:
- unchanged (no vehicle)
- Controls:
- not required
- Amount / concentration applied:
- 0.1 g of undiluted liquid test substance was administered into the conjunctival sac of one eye per rabbit (right eye). The contralateral eye (left eye) remained untreated to serve as a control. (The test substance was too viscous to be drawn into a syringe, therefore 0.1 g aliquots were weighed and administered.)
- Duration of treatment / exposure:
- There was no mentioning in the report that eyes were rinsed after treatment. Consequently the treatment/exposure period was equivalent to the entire observation period following instillation or lasted until removal of the test material by physiological mechanisms, whichever happened sooner.
- Observation period (in vivo):
- 14 days in one animal (sentinel) and 72 hours in the other two animals
- Number of animals or in vitro replicates:
- 3 adult female rabbits
- 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. In addition, eyes of the sentinel animal were checked 7 and 14 days after treatment (Days 8 and 15, respectively) for possible delayed effects.
Equipment used for eye evaluation: Ophthalmoscope or pencil beam torch

- Irritant / corrosive response data:
- Corneal and iridic lesions were not evident throughout the study. Conjunctival redness grade 1 or 2 was seen in all treated eyes at 1, 24 and 48 hours after instillation and was associated with chemosis grade 1 or 2 in two animals at all of these time points and in the third animal at 24 and 48 hours after instillation. In addition, discharge grade 1 was seen in all animals at 1 and/or 24 hours after instillation. All findings were completely reversible, discharge having disappeared by 24 or 48 hours after instillation in individual animals and conjunctival redness and chemosis having completely disappeared by 72 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 no 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 are within the category “not irritating to eyes”. They were fully reversible.
