- DOSAGE PREPARATION: the substance was used as supplied
The administration volume was 1.77 mL/kg b.w.
- CLASS METHOD: acute-toxic-class methode
first step 3 female rats are treated with 2000 mg/kg b.w., no signs of toxicity were observed
second step (after 24 h) 3 female rats are treated with 2000 mg/kg b.w.

Dose descriptor:
LD50
Effect level:
> 2 000 mg/kg bw
Based on:
test mat.
Mortality:
No mortality occurred.
Clinical signs:
No signs of toxicity.
Body weight:
No apparent changes were found in body weight.
Gross pathology:
No abnormalities were found at macroscopic post mortem examination of the animals.
Other findings:
no other findings

no other information

Conclusions:
Under the present test conditions, the test item requires no labelling, as LD50 > 2000 mg/kg b.w., p.o.

Executive summary:

The test item is given to female rats by oral administration to obtain information on the toxicity, in particular, lethality of a test item

Under the present test conditions, a single oral administration of 2000 mg test substance to female rats did not reveal any signs of toxicity. No animal died prematurely. All animals gained the expected body weight. No pathological changes were observed at necropsy

Therefore, the test substance is n o n - t o x i c if swallowed, as LD50 > 2000 mg/kg b.w., p.o.

Endpoint conclusion

Additional information

Justification for selection of acute toxicity – oral endpoint
Only one study available.

Justification for classification or non-classification

Based on the results of the acute oral study and according to the criteria of EC Directive 67/548/EEC and EC Regulation 1272/2008 the test item has a low acute toxicity if swallowed (LD50(rat) > 2000 mg/kg bw). Therefore, the test substance must not be classified.
