- Water: Community tap water from Füllinsdorf, ad libitum.
- Acclimation period: Under laboratory conditions, after health examination. Only animals without any visual signs of illness were used for the study.
ENVIRONMENTAL CONDITIONS
- Temperature (°C): 22 ± 3
- Humidity (%): 30 - 70
- Air changes (per hr): 10 - 15
- Photoperiod (hrs dark / hrs light): 12/12
Administration / exposure
- Type of coverage:
- semiocclusive
- Vehicle:
- water
- Details on dermal exposure:
- One day before treatment, the backs of the animals were clipped with an electric clipper, exposing an area of approximately 10 % of the total body surface. Only those animals without injury or irritation on the skin were used in the test. On test day 1, the test item was applied at a dose of 2000 mg/kg body weight evenly on the intact skin with a syringe and covered with a semi-occlusive dressing. The dressing was wrapped around the abdomen and fixed with an elastic adhesive bandage. Application volume/kg body weight: 6 mL. 24 hours after the application the dressing was removed and the skin was flushed with lukewarm tap water and dried with disposable paper towels. Thereafter, the reaction sites were assessed.

- Gross pathology:
- No macroscopic findings were observed at necropsy.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The LD50 of the test substance is greater than 2000 mg/kg bw.
- Executive summary:
In a GLP-compliant dermal toxicity study, performed according to OECD guideline 402, Wistar rats (5/sex) were treated with the test substance (2000 mg/kg bw) by dermal application. The test substance was diluted in vehicle (water), administered on the skin with a syringe and covered with a semi-occlusive dressing for 24 hours. After 24 hours the dressing was removed and the skin was flushed with lukewarm tap water. A 14-day observation period followed. No deaths occurred during the study and no macroscopic findings were observed. Light red discoloration of the treated skin area produced by the test item was observed in all male and female animals. Two females showed a loss of body weight (0.5 % and 0.6 %) between test day 1 and 8 and another female showed also a loss of body weight (0.3 %) between test day 8 and the end of the observation period. The body weight of the remaining female and all male animals was within the range commonly recorded for this strain and age. Based on the observations, the LD50 of the test substance was determined to be greater than 2000 mg/kg bw.
