Dose (mg/kg bw) Toxicological results  Onset and duration of signs  Onset of mortality
(1st) 2000 0 / 0/ 3 --- --- 
(2nd) 2000 0 / 0/ 3 --- --- 

Toxicological results:

number of dead animals / number of animals with signs after treatment / number of animals treated

Executive summary:

The LD50 cut-off value is > 5000 mg/kg bw based on the result of a study performed according to OECD TG 423. The test dose of 2000 mg/kg was tolerated without any findings.

Dose descriptor:
LD50
Effect level:
> 2 000 mg/kg bw
Based on:
test mat.
Remarks on result:
other: no clinical signs, no effects on weight development and gross pathological findings
Mortality:
none
Clinical signs:
other: none
Gross pathology:
no noticable gross pathological findings
Executive summary:

An acute dermal toxicity study was performed according to OECD TG 402. 2000 mg/kg of the test item was applied semiocclusive on 5 male and 5 female rats for 24 hours. No mortalities, no clinical signs, no effects on weight development and no gross pathological findings were observed during the 14 -days observation period. The resulting LD50 was therefore > 2000 mg/kg bw for both sexes combined.

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed
Dose descriptor:

Additional information

Acute toxicity: oral

The LD50 cut-off value is > 5000 mg/kg bw based on the result of a study performed according to OECD TG 423. The test dose of 2000 mg/kg was tolerated without any findings. Acute toxicity: InhalationNo data available Acute toxicity: dermal

An acute dermal toxicity study was performed according to OECD TG 402. 2000 mg/kg of the test item was applied semiocclusive on 5 male and 5 female rats for 24 hours. No mortalities, no clinical signs, no effects on weight development and no gross pathological findings were observed during the 14 -days observation period. The resulting LD50 was therefore > 2000 mg/kg bw for both sexes combined.
