Results and discussion
Effect levels
- Key result
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- act. ingr.
- Mortality:
- No mortality occurred after a 24-hour dermal exposure of AFLAMMIT PCO 962
administered at 2000 mg/kg bw to Crl:WI male and female rats followed by a 14-day
observation period. - Clinical signs:
- other: Each rat was symptom-free during the entire study. Local sign was not noted in any of the study animals.
- Gross pathology:
- No external or internal macroscopic findings were noted at a dose level of
2000 mg/kg bw at necropsy.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The median lethal dose (LD50) of AFLAMMIT PCO 962 after a single dermal
administration was found to be greater than 2000 mg/kg bw in male and female
Crl:WI rats.
Each rat was symptom-free during the entire study. There was no evidence for adverse effcet.
The study result triggers no classification/labelling:
- Regulation (EC) No 1272/2008 (CLP): none
- GHS (rev. 6) 2015: Unclassified
