Based on the results of above mentioned study the median lethal dose (LD50) of the test substance after single oral administration to male and female rats, observed over a period of 14 days is 5000 mg/kg bw.
Executive summary:

A study was performed to determine the acute oral median lethal dose (LD50) of the test material, administered once per oral gavage as a solution in 25% sesame oil in Wistar rat. The method used followed that described in the OECD Guidelines for Testing of Chemicals (1981) No. 401 "Acute Oral Toxicity" referenced as EU Method B.1 (Acute Toxicity (Oral)).

Ten fasted animals (five per sex) were given a single oral dose of test material at the dose level of 5000 mg/kg bw. No mortality occurred. No clinical signs were observed during the observation period of 14 days. No effect on body weight development was observed. At the end of the observation period all rats were sacrificed with CO2 gas. Gross pathological examination dit not reveal any alteration.

Based on the results of above mentioned study the median lethal dose (LD50) of the test substance after single oral administration to male and female rats, observed over a period of 14 days is 5000 mg/kg bw.
