- TEST SITE PREPARATION:
On the day before treatment, hair was removed with clippers from the dorsolumbar region of each animal. The neat test substance was administered under a 2-ply 25 mm x 25 mm porous gauze pad secured with 'blenderm' surgical tape to intact skin sites moistened with 0.5 mL reverse osmosis water. For exposures of one hour or more each treatment site was covered additionally with cotton wool and "Tubigrip" elasticated bandage dressing for the duration of the exposure period.
On each animal an additional site was similarly treated with the exception of test substance and acted as a control.
TREATMENT PERIOD AND REMOVAL OF TEST SUBSTANCE
At the end of the exposure period, the semi-occlusive dressing and gauze pad were removed and the treatment site was washed with lukewarm water (30-40°C) to remove any residual test substance. The treated area was blotted dry with absorbent paper.
SKIN EVALUATION:
The treated skin patches were evaluated immediately after patch removal (for 3 minute and 1 hour exposures) and at 1, 24, 48 and 72 h afterwards, whereby only the data for the 4 hour exposures were reported.

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. - 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.

- 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.
- 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.

Additional information
Justification for classification or non-classification
In view of the absence of any effects during the skin irritation study and the absence of relevant effects during the eye irritation study, the attained results do not necessitate any classification and labelling regarding skin or eye irritation according to EU classification rules [DIRECTIVE 67/548/EEC and REGULATION (EC) 1272/2008].
