Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No deaths occurred during the study period.
- Clinical signs:
- other: There were no clinical signs of systemic toxiclty. The skin was discoloured with blue at the application site in all animals. The staining persisted on test days 2 to 15. In one male animal the blue discoloured skin was observed until test day 8.
- Gross pathology:
- No macroscopic findings were noted.
Applicant's summary and conclusion
- Interpretation of results:
- other: not classified according to the CLP criteria (EC 1272/2008)
- Conclusions:
- The LD50 (dermal, rat) of test item was found to be greater than 2000 mg/kg bw.
- Executive summary:
Acute dermal toxicity of the test item was evaluated in an experimental study that was performed according to the OECD Guideline 402 (1987) and EU method B.3 (1992). 2000 mg/kg bw of the test item was applied dorsally to 10 rats of both sexes for a duration of 24 hours.
A death rate of 0 % at 2000 mg/kg bw was observed. Local discolouration was observed between 24 hours and end of observation period. The LOGIT-Model could not be applied to these data. The acute dermal toxicity of the test item in rats of both sexes observed over a period of 15 days was estimated to be greater than 2000 mg/kg bw. Therefore, it can be extrapolated that the LD50 (dermal, rat) is greater than 2000 mg/kg bw.
