Endpoint summary
Administrative data
Description of key information
Oral: The LD50 value of the test material was established to be 1720 mg/kg bw.
Dermal: The acute dermal toxicity study with 5000 mg/kg bw of the test substance caused no mortality in rabbits and therefore a LD50 of > 5000 mg/kg bw was derived.
Inhalation: A study was scientifically not necessary since data for two other routes are available
Key value for chemical safety assessment

Additional information
Acute toxicity: oral
In an orale acute toxicity study (1973), 50 rats were orally exposed once with the test substance at concentrations of 1.05, 1.64, 2.05, 2.56 and 5.00 g/kg bw and were observed for a period of 14 days (similar to OECD 401). The LD50 value of the test material was established to be 1720 mg/kg bw.
Acute toxicity: inhalation
The study does not need to be conducted because data for two other routes are available.
Acute toxicity: dermal
In an acute toxicity study (1973), 10 rabbits were dermally exposed once with the test substance at a single dose of 5.00 g/kg bw and were observed for a period of 14 days (similar to OECD 402). No mortallity was observed during the test. The LD50 value of the test material was established to be > 5000 mg/kg bw.
Justification for classification or non-classification
Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
The available experimental test data is reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. Based on available data on acute toxicity via oral and dermal route, the test item is to be classified in category 4 according to Regulation (EC) No 1272/2008 (CLP), as amended for the fifteenth time in Regulation (EU) 2020/1182.
