- Frequency of observations and weighing: Test animals were observed several times on the day of dosing with special attention during the first 4 hours. Thereafter test animals were observed for clinical signs once daily until the end of the observation period. Body weights were recorded on day 1 (prior to test material administration) and on days 8 and 15.

2000 mg/kg bw: A total of 3 animals died (1 dead in group 1 and 2 dead in group 2). - Clinical signs:
- other: 300 mg/kg bw group: reduced spontaneous activity, apathy, recumbency, kyphosis, half eyelid-closure, lethargy, piloerection and bradykinesia. 2000 mg/kg bw group: reduced spontaneous activity, recumbency, lethargy, ataxia, wasp waist, piloerection, abnorm
- Gross pathology:
- Necropsy of surviving animals showed no treatment-related macroscopic findings. Necropsy of animals not having survived until the end of the observation period showed the following: haemorrhagic duodenum, jejunum and illeum. Test item residue was also observed in one animal.
- Interpretation of results:
- Toxicity Category IV
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Under the conditions of this study, the acute oral median lethal dose (LD50) of the test material in the female Wistar strain rat was estimated to be between 300 and 2000 mg/kg bodyweight.
- Executive summary:
The study was performed to assess the acute oral toxicity of the test material in the Wistar strain of rat. The study was performed to GLP and the method was designed to meet the requirements of OECD 423 guideline, EU method B.1 tris, EPA OPPTS 870.1000 and 870.1100 guidelines. A stepwise approach was used to evaluate the toxicity of the test material. Absence or presence of compound-related mortality of the animals dosed at one step determined the next step. Two groups (each of 3 test animals) were used for each dose. The test material was administered orally, after overnight fasting, once only by gavage, as a suspension in cotton seed oil. The test material concentrations in the vehicle were 300 mg/mL and 2000 mg/mL and the administered volume of suspension was 10 mL/kg body weight.Clinical signs and bodyweight development were monitored during the study. All animals were subjected to gross necropsy after an observation period of 14 days. Clinical observations in the 300 mg/kg dose group included: reduced spontaneous activity, apathy, recumbency, kyphosis, half eyelid-closure, lethargy, piloerection and bradykinesia. Clinical observations in the 2000 mg/kg bw group included: reduced spontaneous activity, recumbency, lethargy, ataxia, wasp waist, piloerection, abnormal breathing and half-eyelid closure. Animals of the 300 mg/kg bw dose group recovered within 24 hours and all test animals survived to the end of the study; a total of 3 test animals in the 2000 mg/kg bw dose group were found dead after 24 hours post-exposure of the test material (1 death in group 1 and 2 deaths in group 2). All surviving animals showed expected gains in bodyweight during the study. No abnormalities were noted at necropsy. The acute oral median lethal dose (LD50) of the test material in the female Wistar strain rat was estimated to be between 300 and 2000 mg/kg bw.

Additional information
Acute oral:
The acute oral toxicity of the substance was evaluated in female Wistar rats in a GLP study designed to the requirements of OECD 423. The substance was administered by gavage as a suspension in cottonseed oil. A stepwise approach was used to evaluate the toxicity of the test material. Absence or presence of compound-related mortality of the animals dosed at one step determined the next step. Two groups (each of 3 test animals) were used for each dose. The test material was administered orally, after overnight fasting, once only by gavage, as a suspension in cotton seed oil. The test material concentrations in the vehicle were 300 mg/mL and 2000 mg/mL and the administered volume of suspension was 10 mL/kg body weight. There were no deaths in the 300 mg/kg bw dose group; but a total of 3 deaths in the 2000 mg/kg bw dose group. Signs of systemic toxicity in the 300 mg/kg dose group included: reduced spontaneous activity, apathy, recumbency, kyphosis, half eyelid-closure, lethargy, piloerection and bradykinesia. In the 2000 mg/kg bw group these included: reduced spontaneous activity, recumbency, lethargy, ataxia, wasp waist, piloerection, abnormal breathing and half-eyelid closure. The acute oral LD50 was estimated to be >300 and < 2000 mg/kg bw.
Justification for selection of acute toxicity – oral endpoint
Only one study available; study estimates the LD50 range and therefore provides information on a discriminating dose level (the highest concentration administered that has not caused significant effects to the test organisms).
Justification for classification or non-classification
The substance meets the classification criteria under EU Directive 67/548/EEC as harmful Xn; R22.
The substance meets the classification criteria under Regulation (EC) No 1272/2008 for acute toxicity category 4.
