Interpretation of results:
not classified
Remarks:
Migrated information Criteria used for interpretation of results: other: GHS
Conclusions:
The acute oral median lethal dose (LD50) of the test material in the Sprague-Dawley strain Albino rats was found to be greater than 5000 mg/kg bodyweight. The test substance was classified as non-toxic.
Executive summary:

In an acute oral toxicity study, 2 groups fasted 7 week old Sprague-Dawley strain Albino rats (five male and five female) were given a single oral dose of undiluted test material at a dose level of   5000  mg/kg bw and observed for14 days. No mortality occurred. No signs of systemic toxicity, or behavioral changes were reported during the study, and no abnormalities were noted at necropsy, except one female rat showed mild hydrometra in uterus. All animals showed expected bodyweight gain during the study except female group during day 7 to day 14 period. The oral LD50 value of test material in rats of both sexes was stimulated to exceed 5000 mg/kg bw.

Additional information

The test material was tested for acute toxicity via oral application to rats. An LD50 of > 5000 mg/kg was identified.No mortality occurred. No signs of systemic toxicity, or behavioral changes were reported during the study, and no abnormalities were noted at necropsy, except one female rat showed mild hydrometra in uterus. All animals showed expected bodyweight gain during the study except female group during day 7 to day 14 period.

Justification for classification or non-classification

There are conclusive but not sufficient data for classification of the test item with regard to acute toxicity. The substance is not classified for acute toxicity via oral route in accordance with the CLP Regulation (EC) No 1272/2008.
