CLINICAL EXAMINATIONS
After application the animals were observed individually
1st day: at 30min and at 3h
2nd day: in the morning and in the afternoon
up to 14th day: once daily
Observations included: changes in the skin and fur, eyes, visible mucous membranes, behaviour of animals, somatomotor activity, reactions to stimuli, presence of lacrimation, salivation and discharge from nostrils, function of respiratory, digestive and urogenital system.
PATHOLOGICAL EXAMINATION
All the test animals that survived to the end of the study were sacrificed on the 15th day and gross necroscopy was performed. Nutritious status, body surface, body foramina, thoracic, abdominal and cranial cavity were evaluated. - Sex:
- male

- LD50
- Effect level:
- 6 857 mg/kg bw
- Based on:

dose: 5020 mg/kg bw, 1 male died at day 1
dose: 6310 mg/kg bw, 2 males died at day 1
dose: 7943 mg/kg bw, 3 males died after 3 hours, 7 males died at day 1 - Clinical signs:
- other: The test item caused diarrhoea and faintness in the period up to 3 hour after administration. After 24hours after application the diarrhoea receded. Other finding during clinical observations were normal.
- Gross pathology:
- The test item caused colouration of organs while other patho-morfological signs were not found.
- Interpretation of results:
- other: not classified under Regulation 1272/2008
- Conclusions:
- The substance was tested for acute toxicity oral following OECD 401. The LD50 was found to be equal to 6857 mg/kw bw.
- Executive summary:
The substance was tested for acute toxicity oral following OECD 401. The LD50 was found to be equal to 6857 mg/kw bw.

Additional information
Justification for classification or non-classification
According to the CLP Regulation (EC n. 1272/2008), table 3.1.1, Acute toxicity hazard categories and acute toxicity estimates (ATE) defining the respective categories:
For Acute toxicity oral route:
Category 1: ATE <= 5 mg/kg bw
Category 2: 5 < ATE <= 50 mg/kg bw
Category 3: 50 < ATE <= 300 mg/kg bw
Category 4: 300 < ATE <= 2000 mg/kg bw
The LD50 of the test substance was determined to be 6857 mg/kg bw in the chosen reference test, which is outside the above criteria. Therefore, the test substance is not classified for Acute toxicity by oral exposure.
According to the CLP Regulation (EC n. 1272/2008), table 3.1.1, Acute toxicity hazard categories and acute toxicity estimates (ATE) defining the respective categories:
For Acute toxicity dermal route:
Category 1: ATE <= 50 mg/kg bw
Category 2: 50 < ATE <= 200 mg/kg bw
Category 3: 200 < ATE <= 1000 mg/kg bw
Category 4: 1000 < ATE <= 2000 mg/kg bw
The LD50 of the test substance was determined to be more than 5000 mg/kg bw in the chosen reference test, which is outside the above criteria. Therefore, the test substance is not classified for Acute toxicity by dermal exposure.
