Test animals
- Species:
- rabbit
- Strain:
- Himalayan
- Details on test animals or test system and environmental conditions:
- TEST ANIMALS
-Male, Himalayan strain rabbit were obtained from LPT Laboratory of Pharmacology and Toxicology KG, branch L
-The rats were in Initial body weight of: 2.3 kg (animal 1), 2.1 kg (animal 2) and 2.2 kg (animal 3)
-Rats were approximately: 4 months old
CONDITIONS
-Drinking water was offered ad libitum before and after the exposure period.
-Diet: ssniff® K-H V2333 (ssniff Spezialdiaten GmbH, D-59494 Soest, served as food. Feeding was available ad libitum before and after the exposure period.
- AnimalHousing:
Before and after the 4-hour exposure period, the animals were kept singly in cages measuring 425 mm x 600 mm x 380 mm (manufacturer Dipl. Ing W. EHRET GmbH, D-16352 Schőnwalde). at a room temperature of 20 °C ± 3 °C (maximum range) and relative humidity of 55% ± 15% (maximum range).
Deviations from the maximum ranges caused for example during cleaning procedures are dealt with in SOPs
The rooms were lit (150 lux at approx. 1.5 m room height) and darkened for periods of 12 hour light/12-hour dark cycle (light 6:00 a.m. to 6:00 p.m. to 6:00 a.m.)
Test system
- Type of coverage:
- semiocclusive
- Preparation of test site:
- shaved
- Vehicle:
- water
- Controls:
- yes, concurrent no treatment
- Amount / concentration applied:
- 500 mg/patch and animal
(3000 mg of the test substance was mixed with 3ml aqua ad iniectabilia, 1000 mg of this paste was applied per animal (500 mg test substance/animal)). - Duration of treatment / exposure:
- 4 hours
- Observation period:
- 60min; 24,48 and 72 hours
- Number of animals:
- 3 male
- Details on study design:
- As a general criteria, the body weight of all animals was measured at the beginning of the study.
The evaluation of the skin was based on grading score/scheme.
The test substance was applied to the test site and then covered with a gauze patch. The patch was held in contact with skin with non-irritating tape for the duration of the exposure period.
- Surrounding untreated skin served as a control.
- During four hours of exposure time the animals were in comfortable restrainers. No residual test substance had to be removed, as no test substance was left on the skin after removal of the patch.
During examination of the skin,the skin sites were evaluated immediately before the application of the test substance.
- After the 4-hour exposure period the patch was removed and the skin sites were evaluated.
- Scores were taken 60 minutes, 24, 48 and 72 hours after the patch removal.
- Based on most recent guidelines the skin reactions are monitored until the changes observed have completely subsided.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the present test conditions none of three rabbits exposed for 4 hours to 500 mg CDBA0578BS/patch and animal (semi-occlusive
conditionl showed any substance-related lesions.
There were no systemic intolerance reactions.
