- Details on study design:
- 24 hours before the test, fur was clipped from the dorsal and ventral area of the trunk of the test animals. Care was taken to avoid abrading the skin which could alter its permability. An area of about 6x5 cm of the body dorsal surface was cleared for the application of the test article. This area corresponded to about 10% of the total body surface.
The test article was applied uniformly onto a porous gauze which was moistened with 0.9% NaCl solution. The treated area was covered with the porous gauze dressing fixed to the skin with hypoallergenic non-irritaing tape. The test site was further covered in a suitable manner in order to ensure that the animals could not ingest the test substance. At the end of the exposure period the residual test article was wiped off with water.
- Duration of observation period following administration: 14 days
- Frequency of observations : 30 min, 2, 4 and 6 hours on the first day after the administration, twice a day up to termination
- Other examinations performed: clinical signs, body weight, histopathology, gross pathology
Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No mortality occurred.
- Clinical signs:
- other: No general or local clinical abnormalities were seen in any animal.
- Gross pathology:
- No apprecible changes were evident in the treated animals of either sex at the autopsy carried out at the end of the observation period.
Any other information on results incl. tables
The day of treatment was considered day 1 of the study. The animals were weighed twice before treatment (at randomization and on day 1 just before treatment) and on day 8 and 15. They were clinically observed for 14 days after the 24 -hour exposure period. On day 16 all rats were killed (fasted overnight) by excision of the femoral arteries after i.p. overdosage anesthesia with 5% sodium pentobarbital and were submitted to a thorough autopsy.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- No animals died and no general or local clinical signs or body weight abnormalities were observed in any treated rat during the observation period. No macroscopic findings were evident at the final autopsy.
In conclusion, the test substance, when administerd by dermal route to the rat, did not cause mortality or show appreciable toxic effects at the limit dose of 2000 mg/kg.
The LD50 by dermal route is higher than 2000 mg/kg.
