- Executive summary:
In an acute oral toxicity study performed similar to OECD 401 (pre-OECD, pre-GLP) 10 rats were administered the test substance orally at a dose level of 5000 mg/kg bw. During the 14 -day observation period 2/10 rats died. Mortality was observed at day 5 and 12. The clinical sign observed was lethargy. The acute oral LD50 for the test substance in rats was determined to be >5000 mg/kg bw.

Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed
- Quality of whole database:
- The acute oral toxicity result is of sufficient quality and adequate for this dossier.
Additional information
Acute oral toxicity:
In an acute oral toxicity study performed similar to OECD 401 (pre-OECD, pre-GLP) 10 rats were administered the test substance orally at a dose level of 5000 mg/kg bw. During the 14 -day observation period 2/10 rats died. Mortality was observed at day 5 and 12. The clinical sign observed was lethargy. The acute oral LD50 for the test substance in rats was determined to be >5000 mg/kg bw.
Additional information:
In the acute oral toxicity study of Moreno, 1973 also a dermal toxicity study is included. The acute dermal toxicity study was conducted with 10 rabbits receiving a dermal application of 5000 mg/kg bw of the test material. The animals were observed for mortality and/or clinical signs for 14 days. No symptoms were observed and 0/10 animals died. The dermal LD50 exceeded 5000 mg/kg bw and this result does not have an impact on the classification.
Justification for classification or non-classification
The substance does not have to be classified for acute and dermal oral toxicity in accordance with EU CLP Regulation (EC) No. 1272/2008 and its amendments.
