- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the conditions of the present study, a single oral application of the test item Tall oil, polym., oxidized to rats at a dose of 300 mg/kg body weight was associated with signs of toxicity but not mortality.
Under the conditions of the present study, a single oral application of the test item Tall oil, polym., oxidized to rats at a dose of 2000 mg/kg body weight was associated with signs of toxicity but not mortality.
The median lethal dose of Tall oil, polym., oxidized after a single oral administration to female rats, observed over a period of 14 days is:
LD50 cut-off (rat): 5000 mg/ kg bw - Executive summary:
Two groups, each of three female WISTAR Crl: WI(Han) rats, were treated with the test item by oral gavage administration at a dosage of 300 mg/kg body weight. The test item was suspended with the vehicle corn oil at a concentration of 0.03 g/mL and administered at a dose volume of 10 mL/kg.
Two groups, each of three female WISTAR Crl: WI(Han) rats, were treated with the test item by oral gavage administration at a dosage of 2000 mg/kg body weight. The test item was suspended with the vehicle corn oil at a concentration of 0.2 g/mL and administered at a dose volume of 10 mL/kg.
All animals used in the study after their entrance at BSL were allowed to acclimatise to the laboratory conditions for at least 5 days. The animals were observed on delivery, on inclusion in the study and before administration for mortality/morbidity and other clinical signs. All animals were examined for clinical signs several times on the day of dosing and once daily until the end of the observation period. Their body weights were recorded on day 1 (prior to the administration) and on days 8 and 15. All animals were necropsied and examined macroscopically.
All animals survived until the end of the study showing signs of toxicity.
The most relevant clinical findings in the animals treated with the test item at a dose of 300 mg/kg bw were reduced spontaneous activity, piloerection, half eyelid-closure and hunched posture. All animals recovered within up to 2 days post-dose.
The most relevant clinical findings in the animals treated with the test item at a dose of 2000 mg/kg bw were reduced spontaneous activity, piloerection, half eyelid-closure, hunched posture and sunken flanks. All animals recovered within up to 3 days post-dose.
Throughout the 14-day observation period, the weight gain of the animals was within the normal range of variation for this strain.
Macroscopic findings of animals:
At necropsy, no treatment-related macroscopic findings were observed in any animal of any step.
