Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Remarks on result:
- other: No mortalities and no clinical signs of toxicity occurred
- Mortality:
- No mortalities occurred.
- Clinical signs:
- other: No clinical signs of toxicity occurred in any of the animals.
- Gross pathology:
- Macroscopic examination of the animals did not reveal any abnormalities.
- Other findings:
- No erythema or oedema was observed during the observation period. Therefore this study does not indicate skin irritation.
Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- In an acute dermal toxicity study with rats with the substance, performed in accordance with OECD 402 (1987) and according to GLP principles, a LD50 of >2000 mg/kg bw was determined.
- Executive summary:
The acute dermal toxicity of the substance was determined in the rat, in accordance with OECD 402 (1987) and according to GLP principles. The substance was administered to five Sprague-Dawley rats of each sex by a single dermal application of 2000 mg/kg bw for 24 hours. No mortality and no clinical signs of toxicity occurred. Body weight determinations and macroscopic examination of the animals did not reveal any abnormalities. The dermal LD50 value of the substance in Sprague-Dawley rats was established to be >2000 mg/kg bw. Based on this result, the substance does not need to be classified for acute toxicity by the dermal route. In addition, as no erythema or oedema was observed during the observation period, this study does not indicate skin irritation potential.
