Conclusions:

Based on the results of the experiment, it is concluded that the LD50 cut off value for the test item is 5000 mg/kg body weight when administered as a single dose by oral gavage to female Sprague Dawley rat as per OECD Guidelines for Testing of Chemicals (No. 423, Section 4: Health Effects) on conduct of “Acute Oral Toxicity - Acute Toxic Class Method” and classified as “Category 5 or Unclassified (2000 < ATE ≤ 5000)” as per the Globally Harmonized System of Classification and Labelling of Chemicals (GHS).

Executive summary:

The test item, ESTERI METILICI ACIDI GRASSI DA OLIO ESSEBIOCHLOR45 was evaluated for Acute Oral Toxicity in Sprague Dawley rats.
A starting dose of 300 mg/kg body weight was selected from the four fixed dosen levels of 5, 50, 300 and 2000 mg/kg body weight, since there is no information available for the test item. A total of 12 females (3 females for each Step-I, Step-I confirmation, Step-II and Step-II confirmation) were used for the experiment. All the animals of Step-I and Step-I confirmation were administered with 300 mg/kg body weight and Step-II and Step-II confirmation were administered with 2000 mg/kg body weight of the test item by oral route. All the animals were observed for clinical signs of toxicity and mortality at 20 to 30 mins, 1 hr (±10 mins), 2 hrs (±10 mins), 3 hrs (±10 mins) and 4 hrs (±10 mins) post dosing on day 1 and once daily thereafter for clinical signs of toxicity and twice daily for mortality during the 14 days observation period. Body weights were recorded at receipt, on day 1 before test item administration, on day 8 and 15 during the observation period. At the end of observation period, all the animals were humanely sacrificed by carbon dioxide asphyxiation, subjected to necropsy and gross pathological examination.
In Step-I and Step-I confirmation, the animals dosed with 300 mg/kg body weight did not revealed any clinical signs of toxicity and no mortality was observed. Also in Step-II and Step-II confirmation, the animals dosed with 2000 mg/kg body weight did not revealed any clinical signs of toxicity and no mortality was observed. No treatment related changes were observed in body weight and percent change in body weight with respect to day 1 at 300 mg/kg body weight and 2000 mg/kg body weight. All the animals revealed physiologically normal increase in the body weight. No gross pathological changes were observed in any of the animals at 300 mg/kg body weight and 2000 mg/kg body weight.
