The study is reliable without restriction (GLP-study according to OECD guideline 423).
Single doses of 2000 and 1000 mg/kg bw of the unchanged test material were given to four administration groups of three fasted female Wistar rats, each, by gavage in a sequential manner. After administration a 14 -day observation period followed.
Four animals of the 2000 mg/kg administration groups and one animal of the 1000 mg/kg administration groups were found dead from study day 1 until including study day 2.
Clinical observation in the 2000 mg/kg administration groups revealed impaired and poor general state, dyspnoea, lateral position, staggering, piloerection, salivation and lacrimation. Findings were observed from hour 0 until including study day 6 after administration. Clinical observation in the 1000 mg/kg administration groups revealed impaired general state, dyspnoea, staggering, piloerection, salivation and lacrimation. Findings were observed from hour 0 until including study day 5 after administration.
The mean body weights of the surviving animals of the administration groups increased throughout the study period.
During necropsy findings in the animals that died in the 2000 mg/kg and 1000 mg/kg administration groups comprised few, several or many black erosions/ulcers in the glandular stomach and red or slight red discoloration of contents of the small intestine. In addition one animal of the 1000 mg/kg administration group that died showed dark red discoloration of contents of the large intestine and beige discoloration of the liver. No macroscopic pathologic abnormalities were noted in the surviving animals of the 2000 mg/kg and 1000 mg/kg administration groups examined at the end of the observation period.
Conclusion: Under the conditions of this study the median lethal dose of the test substance after oral administration was found to be greater than 1000 mg/kg bw and less than 2000 mg/kg bw in rats.

- GENERATION OF TEST ATMOSPHERE / CHAMBER DESCRIPTION
The test substance was filled to a height of 5 cm in a glass bottle (fritted glass flask, pore-size 90 - 150 µm, diameter 30 mm), and the net weight was determined. A stream of 200 l/h compressed air was supplied to the fritted glass flask containing the product, which had been placed in a water bath maintained at 20 +/- 1°C by a thermostat. The mixture of air and test substance generated in this way was passed through a glass distributor to 6 glass tubes in which 3 male and 3 female animals had been placed. The emerging mixtures of test substance and air were exhausted. After 30 min, the fritted glass flask was replaced by a new one filled with fresh test substance as described above. This generator was then used for the whole remaining time of the test.

The acute dermal toxicity of the test substance was investigated in a group of 3 male and 3 female Vienna White rabbits. The test material was applied undiluted to the clipped epidermis (dorsal and dorsolateral parts of the trunk) of each animal at a dose level of 2000 mg/kg bw, and was covered by a semiocclusive dressing for 24 h.
There were no signs of systemic toxicity. After the removal of the dressing no skin reactions could be observed. All animals exhibited scaling of skin findings 7 days after application. This skin reaction persisted in the male animals until study termination (day 14). The expected body weight gain was observed. One male animal died one day after application (no further mortality). Necropsy of the animal that died revealed general congestion and dilation of the right ventricle of the heart. No abnormalities were observed at the end of the study in the surviving animals.
Conclusions: The acute dermal LD50 of the test material is >2000 mg/kg bw for male and female rabbits.

Additional information
Oral exposure route:
In the key study conducted by BASF AG (2005) single doses of 2000 and 1000 mg/kg bw of the unchanged test material were given to four administration groups of three fasted female Wistar rats, each, by gavage in a sequential manner. After administration a 14 -day observation period followed. The LD50 was found to be greater than 1000 mg/kg bw and less than 2000 mg/kg bw. Clinical symptoms were an impaired and poor general state, dyspnoea, lateral position, staggering, piloerection, salivation and lacrimation. At necropsy, findings in the animals that died comprised few, several or many black erosions/ulcers in the glandular stomach and red or slight red discoloration of contents of the small intestine. In addition, one animal of the 1000 mg/kg administration group that died showed dark red discoloration of contents of the large intestine and beige discoloration of the liver. No macroscopic pathologic abnormalities were noted in the surviving animals examined at the end of the observation period.
Two other acute oral LD50s in rats ranged between 1150 and 1444 mg/kg bw (BASF AG 1981, Air Products and Chemicals, Inc. 1991). These studies do not provide additional information on the acute oral toxicity of the test substance.
Inhalation exposure route:
No mortality occured in an acute vapour inhalation study comparable to the inhalation hazard test described in the Annex of OECD Guideline 403 with acceptable restrictions (non-GLP, low number of animals). In this study 3 male and 3 female Sprague-Dawley rats were exposed for 7 hours to a saturated vapour of the test substance. Clinical signs during exposure were attempts to escape and wiping of snouts. After exposure no clinical signs were observed. No mortality occurred during the 14 days of post-exposure observation period. Nothing abnormal was detected in the organs at necropsy (BASF AG 1981).
Dermal exposure route:
The dermal LD50 in a group of 3 male and 3 female Vienna White rabbits was found to be greater than 2000 mg/kg bw (BASF AG 1992). In this study according to OECD Guideline 402 no signs of systemic toxicity could be observed. One male animal died one day after application (no further mortality). Necropsy of the animals that died revealed general congestion and dilation of the right ventricle of the heart. No abnormalities were observed at the end of the study in the surviving animals.
Other exposure routes:
A LD50 of approx. 100 mg/kg was determined after intraperitoneal injection of the test substance in groups of five male and five female mice per dose (BASF AG, 1982).
Justification for classification or non-classification
GHS classification according to Annex I 1272/2008 CLP (EU GHS):
- Oral route: Acute Category 4
- Dermal route: no classification required
- Inhalation route (vapour): no classification required
