The potential acute toxicity of TPS 44 was evaluated in rats according to the recommendations of the O.E.C.D. Guideline No. 401 (O.E.C.D., 24th February 1987) for the testing of chemicals administered by oral route and the Principles of Good Laboratory Practice (O.E.C.D., 12th May 1981). TPS 44 was administered by oral route to a group of 10 fasted Sprague-Dawley rats (5 males and 5 females). TPS 44 was administered in its original form at a dose level of 2000 mg/kg at a volume taking into consideration that the specific gravity (SG) of TPS 44 was 1.007. The mortality, general behaviour and body weight gain of the animals were observed for a period of 14 days after the single administration of TPS 44. A necropsy was performed on each animal sacrificed at the end of the study.
A slight to well-defined decrease in spontaneous activity and respiratory difficulties were observed in all animals within the hours following the treatment. From day 2 to day 15, the general behaviour returned was normal. No deaths occurred at the dose level of 2000 mg/kg. The body weight gain of the animals was not influenced by the treatment. The macroscopic examination revealed no abnormalities in the animal sacrificed at the end of the study.
Under these experimental conditions, the LD0 of TPS 44 administered by oral route in rats was 2000 mg/kg bw.

Additional information
Oral route
The potential acute oral toxicity of the registered substance was evaluated in rats according to the OECD guideline No. 401 and in compliance with GLP (Clouzeau, 1992a). The registered substance was administered by oral route to a group of 10 fasted Sprague-Dawley rats (5 males and 5 females). The registered substance was administered in its original form at a dose level of 2000 mg/kg at a volume taking into consideration that the specific gravity (SG) was 1.007. The mortality, general behaviour and body weight gain of the animals were observed for a period of 14 days after the single administration of the registered substance. A necropsy was performed on each animal killed at the end of the study. A slight to well-defined decrease in spontaneous activity and respiratory difficulties were observed in all animals within the hours following the treatment. From day 2 to day 15, the general behaviour returned to normal. No deaths occurred at the dose level of 2000 mg/kg. The body weight gain of the animals was not influenced by the treatment. The macroscopic examination revealed no abnormalities in the animal sacrificed at the end of the study. The LD0 of the registered substance administered by oral route in rats is 2000 mg/kg bw (LD50 =>2000 mg/kg).
Dermal route
The acute toxicity of the registered substance by dermal route was evaluated in rats according to the OECD guideline No. 402 and in compliance with GLP (Clouzeau, 1993). the registered substance was administered by dermal route to a group of 10 Sprague-Dawley rats (5 males and 5 females). The registered substance in its original form was applied directly to the skin at a dose of 2000 mg/kg, taking into consideration a specific gravity (SG) of 1.007. After 24 hours under a semi-occlusive dressing, no residual test substance was observed on removal of the dressing. The animals were checked for clinical signs, mortality and body weight gain for a period of 14 days following the single application of the test substance. A necropsy was performed on each animal sacrificed at the end of the study. The general behaviour and body weight gain of the animals were not affected by treatment with the test substance. No deaths occurred at 2000 mg/kg. A macroscopic examination revealed no abnormalities in the animals sacrificed at the end of the study. The LD0 of the registered substance, when administered by dermal route in rats is 2000 mg/kg (LD50 =>2000 mg/kg). No signs of toxicity were observed at this dose.
Justification for classification or non-classification
No mortality was observed in rats dosed with the registered substance at 2000 mg/kg bw by the oral and dermal routes. Therefore, according to the EC regulation No 1272/2008, no classification is warranted.
