- rabbit
- Strain:
- New Zealand White
- Details on test animals or test system and environmental conditions:
- TEST ANIMALS
- Source: Harlan Laboratories UK Limited, Bicester, Oxon, UK
- Age at study initiation: 12 - 20 weeks old
- Weight at study initiation: 2.0 - 3.5 kg
- Housing: The animals were individually housed in suspended cages.

- Humidity (%): 30-70
- Air changes (per hr): 15
- Photoperiod (hrs dark / hrs light): 12/12
Test system
- Type of coverage:

- shaved
- Vehicle:
- unchanged (no vehicle)
- Controls:
- other: Not required, untreated sites of the same animal served as control.
- Amount / concentration applied:
- TEST MATERIAL
- Amount(s) applied (volume or weight with unit): 0.5 mL - Duration of treatment / exposure:
- 3 min, 1 and 4 h
- Observation period:
- 72 h
Reading time points: 1, 24, 48 and 72 h - Number of animals:
- 3
- Details on study design:
- TEST SITE
- Area of exposure: 3 suitable sites were selected on the back of the rabbit. The test substance was introduced under a 2.5cm x 2.5cm cotton gauze patch.
- Type of wrap if used: Each patch was secured in position with a strip of surgical adhesive tape. To prevent the animal interfering with the patches, the trunk of the rabbit was wrapped in an elasticated corset for the duration of the exposure period.
REMOVAL OF TEST SUBSTANCE
- Washing (if done): Any residual test material was removed by gentle swabbing with cotton wool soaked in distilled water.
- Time after start of exposure: 3 min, 1 h and 4 h
SCORING SYSTEM: Draize scoring system

Applicant's summary and conclusion
- Interpretation of results:
- other: CLP/EU GHS criteria not met, no classification required according to Regulation (EC) No 1272/2008
- Conclusions:
- Under the conditions of the Acute Dermal Irritation/Corrosion Test in rabbits the test substance does not possess any skin irritating potential.
