Administration / exposure

- Amount of vehicle (if gavage): 10 mL/kg
- Justification for choice of vehicle: based on trial formulations performed at NOTOX and on test substance data supplied by the sponsor
MAXIMUM DOSE VOLUME APPLIED: 10 mL/kg
DOSAGE PREPARATION (if unusual):
The formulations (w/w) were prepared within 4 hours prior to dosing, and were flushed with nitrogen. Homogeneity was accomplished to a visually acceptable level. In order to obtain homogeneity, the test substance formulations were heated in a water bath with a maximum temperature of 45ºC for a maximum of 11 minutes. The test substance (formulations) were allowed to cool down to a temperature of maximally 40ºC prior to dosing. Adjustment was made for specific gravity of the vehicle and for density of the test substance. The concentration of the test substance in vehicle was varied to allow constant dosage volume in terms of mL/kg body weight.

Applicant's summary and conclusion
- Interpretation of results:
- Category 4 based on GHS criteria
- Conclusions:
- The oral LD50 value of Oleyl dipropylenetriamine in Wistar rats was established to be within the range of 300-2000 mg/kg body weight, with a cut-off value of 500 mg/kgbw.
- Executive summary:
Oleyl dipropylenetriamine (Triameen OV) was tested for acute oral toxicity by Acute Toxic Class method. Test substance was dissolved in PG and dosed by gavage at 10 mL/kg bw.
The incidence of mortality was as follows, presented in chronological order of treatment:
Dose level Mortality Date of treatment
300 mg/kg 0/3 05 June 2009
300 mg/kg 0/3 09 June 2009
2000 mg/kg 3/3 16 June 2009
The decedents were found on Day 2 or 4 post-treatment.
Animals at 300 mg/kg showed hunched posture, uncoordinated movements and/or piloerection between days 1 and 3.
Animals at 2000 mg/kg showed hunched posture, lethargy, piloerection, uncoordinated movements, laboured respiration, rales, ptosis, hypothermia, watery discharge from the eyes and/or chromodacryorrhoea prior to death.
The body weight gain shown by animals at 300 mg/kg/day over the study period was considered to be normal.
Animals at 2000 mg/kg showed weight loss of reduced weight gain prior to death.
One animal at 2000 mg/kg showed a stage of beginning autolysis. No macroscopic abnormalities were noted in the other animals at 2000 mg/kg, and in the animals at 300 mg/kg.
The oral LD50value of Oleyl dipropylenetriamine in Wistar rats was established to be within the range of 300-2000 mg/kg body weight.
According to the OECD 423 test guideline, the LD50 cut-off value was considered to be 500 mg/kg body weight.
