Description of key information
The objective was the evaluation of the acute toxicity of the test substance, by in vivo test models
In an acute oral toxicity study with Wistar Han rats, performed according to OECD/EC guidelines, the oral LD50 value of the test substance was established to exceed 2000 mg/kg body weight.
According to the OECD 423 test guideline, the LD50 cut-off value was considered to exceed 5000 mg/kg body weight.

- Details on study design:
- The toxicity of the test item was assessed by stepwise treatment of groups of 3 females. The absence or presence of mortality of animals dosed at one step determined the next step, based on the test procedure defined in the guidelines. The onset, duration and severity of the signs of toxicity were taken into account for determination of the time interval between the dose groups. The first group was treated at a dose level of 2000 mg/kg. Based on the results, one additional group was dosed at 2000 mg/kg

Clinical signs: At periodic intervals on the day of dosing (Day 1) and once daily thereafter, until Day 15
Necropsy of survivors performed: All moribund animals and animals surviving to the end of the observation period were sacrificed by oxygen/carbon dioxide procedure. All animals assigned to the study were subjected to necropsy and descriptions of all internal macroscopic abnormalities were recorded
Other examinations performed: none - Statistics:
- No statistical analysis was performed (The method used is not intended to allow the calculation of a precise LD50 value).

- GHS criteria not met
- Remarks:
- The test substance does not have to be classified and has no obligatory labelling requirement for acute oral toxicity according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) of the United Nations (2015) (including all amendments) and Regulation (EC) No 1272/2008 on classification, labelling and packaging of items and mixtures (including all amendments).
- Conclusions:
- In an acute oral toxicity study with Wistar rats, performed according to OECD/EC guidelines, the oral LD50 value of the test substance was established to exceed 2000 mg/kg body weight.
According to the OECD 423 test guideline, the LD50 cut-off value was considered to exceed 5000 mg/kg body weight.
Based on these results, the test substance does not have to be classified and has no obligatory labelling requirement for acute oral toxicity according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) of the United Nations (2015) (including all amendments) and Regulation (EC) No 1272/2008 on classification, labelling and packaging of items and mixtures (including all amendments). - Executive summary:
The acute oral toxicity of the test substance in rats was assessed by the Acute Toxic Class Method according to OECD guidelines and GLP principles. The test substance was administrated by oral gavage to two groups of three female Wistar rats at 2000 mg/kg body weight, stepwise. No mortality occurred. Hunched posture, uncoordinated movements and/or piloerection were noted for all the animals on Day 1. No changes in body weight gain were noted in exposed animals, and no toxicological significant abnormalities were found at macroscopic post mortem examination of the animals. The oral LD50 value was established to exceed 2000 mg/kg body weight. According to the OECD 423 guideline, the LD50 cut-off value was considered to exceed 5000 mg/kg body weight.
Based on these results, the test substance does not have to be classified and has no obligatory labelling requirement for acute oral toxicity according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) of the United Nations (2015) (including all amendments) and Regulation (EC) No 1272/2008 on classification, labelling and packaging of items and mixtures (including all amendments).

Additional information
Acute Toxicity: oral
The acute oral toxicity of the test substance in rats was assessed by the Acute Toxic Class Method according to OECD guidelines and GLP principles. The test substance was administrated by oral gavage to two groups of three female Wistar Han rats at 2000 mg/kg body weight, stepwise. No mortality occurred. Hunched posture, uncoordinated movements and/or piloerection were noted for all the animals on Day 1. No changes in body weight gain were noted in exposed animals, and no toxicological significant abnormalities were found at macroscopic post mortem examination of the animals.
The oral LD50 value was established to exceed 2000 mg/kg body weight. According to the OECD 423 guideline, the LD50 cut-off value was considered to exceed 5000 mg/kg body weight.
Acute Toxicity: dermal
In accordance with column 2 of REACH Annex VIII, an acute dermal study (required in the section 8.5.3) is not considered necessary as the substance does not meet the criteria for classification as acute toxicity or STOT SE by the oral route.
Justification for selection of acute toxicity - oral end point.
The study has been performed according to OECD and/or EC guidelines and according to GLP principles and resulted in an LD50 cut-off value suitable for classification
Justification for classification or non-classification
Based on the results from OECD guideline 423, the oral LD50 value was established to exceed 2000 mg/kg body weight. According to the OECD 423 guideline, the LD50 cut-off value was considered to exceed 5000 mg/kg body weight.
Based on these results, the test substance does not have to be classified and has no obligatory labelling requirement for acute oral toxicity according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) of the United Nations (2015) (including all amendments) and Regulation (EC) No 1272/2008 on classification, labelling and packaging of items and mixtures (including all amendments).
