- MAXIMUM DOSE VOLUME APPLIED: 2000 mg/kg bw
DOSAGE PREPARATION:
- The dosing formulations were stirred continuously during administration.
CLASS METHOD:
- Rationale for the selection of the starting dose: The dose levels were based on the OECD test guidelines and were selected from the series 5 (lowest dose level), 50, 300 and 2000 (highest dose level) mg/kg body weight. The starting dose level should be the one that is likely to produce mortality in at least some of the animals and was selected based on available toxicity data of the test item. - Doses:
- The study was conducted in a stepwise manner with four groups of 3 females. The first group was treated at a dose level of 2000 mg/kg. Based on the results, the second group was dosed at 2000 mg/kg two days after the first group based on the absence of severe tox signs. Based on results, two additional groups were dosed at 300 mg/kg.
- No. of animals per sex per dose:
- 12 females (3 animals/dose group)
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing:
*Mortality/Viability: twice daily;
*Body weights: on the day of dosing (fasted weight) and on days 1 (pre-administration), 8 and 15;
*Clinical signs: at periodic intervals on the day of dosing (day 1) and once daily thereafter
- Necropsy of survivors performed: yes
- Other examinations performed: no - Statistics:
- The LD50 cut-off value was established based on OECD guideline 423. No statistical analysis was performed (the method used is not intended to allow the calculation of a precise LD50 value).

- At 300 mg/kg, no mortality occurred. - Clinical signs:
- other: - At 2000 mg/kg, for the first dose group, hunched posture and piloerection were noted between days 1 and 3. In addition, lethargy, hunched posture, piloerection, chromodacryorrhoea, lean appearance and/or ptosis were noted prior to sacrifice on day 6. At
- Gross pathology:
- General emaciation, abnormalities of the stomach (irregular surface of the forestomach) and adrenal glands (both sides enlarged) and yellowish watery-cloudy contents of the jejunum,
ileum and caecum were found in three out of five animals that died or were sacrificed for humane reasons during the study, at macroscopic post mortem examination. Macroscopic
post mortem examination of the other animal that was sacrificed during the study and of the surviving animals at termination did not reveal any abnormalities.
Applicant's summary and conclusion
- Interpretation of results:
- Category 4 based on GHS criteria
- Remarks:
- Classified Category 4 according to Regulation (EC) No. 1272/2008
- Conclusions:
- In an acute oral toxicity study with rats, performed according to OECD/EC test guidelines, the LD50 of N-(Oleyl alkyl)-1,3-propanediamine mono oleate was established to be within the range of 300-2000 mg/kg body weight, with a cut-off of 500 mg/kg bw.
- Executive summary:
Acute oral toxicity of N-(Oleyl alkyl)-1,3-propanediamine mono oleate was evaluated in an OECD 423 (Acute Toxic Class Method)study, performed under GLP.
Dosing was done by oral gavage to groups of three female Wistar rats in a volume of 10 mL/kg bw propylene glycol. The first group was dose at 2000 mg/kg body weight. In a stepwise procedure three additional groups of three females were dosed at 2000, 300 and 300 mg/kg body weight.
Mortality: At 2000 mg/kg, four animals were killed in extremis on day 6 and one animal was found dead on day 7. in the first three animals, 2 were sacrificed on day 6, and one was found 1 dead day 7. From the second three animals that were already dosed in the mean-time, 2 were sacrificed day 6 and one survived until end of observation period. At 300 mg/kg, no mortality occurred. Severe effects were observed at clinical observations 2000 mg/kg bw, especially prior to sacrifice. At 300 mg/kg, hunched posture, uncoordinated movements and/or piloerection were noted for the animals between Days 1 and 6.
Macroscopic Findings involved general emaciation, abnormalities of the stomach, enlarged adrenal glands and yellowish watery-cloudy contents of the intestines were found in four out of five animals that died or were sacrificed. Macroscopic post mortem examination of the other animal that was sacrificed during the study and of the surviving animals at termination did not reveal any abnormalities.
Regarding dosing a second group at 2000 mg/kg: the second group was dosed two days after the first group based on the absence of severe tox signs. Unfortunately delayed toxicity resulting in death was noted for the animals after dosing the second group.
The LD50 is concluded to be between 300 and 2000 mg/kg bw, with a cut-off of 500 mg/kg bw.
