Endpoint summary

Description of key information

In an acute oral toxicity study in mouse, a LD50 of 14300 mg/kg bw was determined (reference 7.2.1 -1).

In an acute oral toxicity study in dog, a LD50 of above 7000 mg/kg bw was determined (reference 7.2.1 -2).

In an acute oral toxicity study in monkey, a LD50 of above 7000 mg/kg bw was determined (reference 7.2.1 -3).

Additional information

There are data on acute oral toxicity of the test item in three different species (mouse, dog and monkey) available (reference 7.2.1 -1 to 7.2.1 -3). The determined LD50 in three different species (mouse: 14300 mg/kg bw, dog: 7000 mg/kg bw, monkey: 7000 mg/kg bw) exceeds the limit value of 2000 mg/kg bw by far and indicates a very low acute oral toxicity of the test item. Based on these information it is very likely, that a study according to OECD guideline 423 in rat will also result in a LD50 of above 2000 mg/kg bw. Following the principle of minimising/avoiding unnecessary animal testing, the performance of a new guideline study is not indicated. According to Regulation EC No 1907/2006, Annex XI available data are regarded as suitable to cover the endpoint 7.2.1 acute oral toxicity.

Justification for classification or non-classification

Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
The available data are suitable for classification purposes under Regulation 1272/2008 (CLP). As a result the test item is not considered to be classified for acute oral toxicity under Regulation (EC) No 1272/2008, as amended for the tenth time in Regulation (EU) No 2017/776.
