- Species: Albino rabbits
Source: National Toxicology Centre
Weight range: 1.8 to 2.0 kg
Age: 6 to 9 weeks
Sex: male and female
Number: 3 per sex
Housing: The animals were housed singly.
Diet: Pelleted feed
Water: Community tap water ad libitum
Room temperature: 19 - 22°C
Relative humidity: 35% - 75%
Light cycle: 12 hours light, 12 hours dark.
Test system
- Type of coverage:
- semiocclusive
- Preparation of test site:
- shaved
- Vehicle:
- unchanged (no vehicle)
- Controls:
- yes
- Amount / concentration applied:
- Test substance used directly in 0.5 ml quantity.
- Duration of treatment / exposure:
- Once the test material was applied the animals were housed singly with a plastic collar around their neck to avoid ingestion of test material. After 24 hours any unabsorbed test material was removed.
- Observation period:
- Each site of application was carefully examined, observed and the reaction evaluated according to Draize's method at 24, 48 and 72 hours post application.
- Number of animals:
- Six rabbits, three per sex were used for this study.
- Details on study design:
- The hair of the back on both sides of the vertebral column was removed with the help of electric clippers, one day before the treatment. The test material in the amount of 0.50 ml was applied to the intact and abraded skin sites of each test animal. Care was taken to note that the abrasions penetrate the Stratum correum but not the dermis. A gauze patch was secured over each treated area by means of an adhesive tape.
The animals were house singly with a plastic collar around their neck for 24 hours to avoid the ingestion of the test material. The patch and the unabsorbed test material were removed after 24 hours.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test substance caused no irritation to thh skin in rabbits.
- Executive summary:
The test material was applied in the amount of 0.5 ml to the shaven back skin, both intact and abraded skin sites, of six rabbits (three per sex). Each site of application was carefully observed and the reaction evaluated according to Draize's method at 24, 48 and 72 hours post application.
The test material caused no irritation to the skin in rabbits till the end of the observation period.
The primary skin irritation index was 0.00.
