Administrative data
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).

Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed
- Dose descriptor:
- discriminating dose
- Value:
- 7 000 mg/kg bw
- Quality of whole database:
- Data from three different species are available which all show very low acute toxicity in older studies.
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.
