Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- corn oil
- Remarks:
- (Fagron Capelle a/d IJssel, The Netherlands) (specific gravity 0.92)
- Details on oral exposure:
- GAVAGE METHOD: plastic feeding tubes
Frequency: single dosage, on Day 1
VEHICLE
- Justification for choice of vehicle: The vehicle was selected based on trial preparations performed at WIL Research Europe
MAXIMUM DOSE VOLUME APPLIED: 10 mL/kg bw
DOSAGE PREPARATION
- The preparations (w/w) were kept at room temperature and were dosed within 4 hours after adding the vehicle to the test substance
- Homogeneity was assessed by visual inspection of the solutions and the formulations were stirred during dosing, which ensures homogeneity sufficient for these kinds of studies
- Adjustment was made for specific gravity of the vehicle
- The concentration of the test substance in vehicle was varied to allow constant dosage volume in terms of mL/kg body weight
CLASS METHOD (if applicable)
- Rationale for the selection of the starting dose: Based on anticipated mortality at the next higher dose - Doses:
- - 300 mg/kg bw
- 2000 mg/kg bw - No. of animals per sex per dose:
- - 300 mg/kg bw: 3
- 2000 mg/kg bw: 6 (2 groups of three females) - Control animals:
- no
- Details on study design:
- - The toxicity of the test substance was assessed by stepwise treatment of groups of 3 females. The first group was treated at a dose level of 300 mg/kg bw. The absence or presence of mortality of animals dosed at one step determined the next step, based on the test procedure defined in the guidelines. The onset, duration and severity of the signs of toxicity were taken into account for determination of the time interval between the dose groups.
- Animals were deprived of food until 3-4 hours after administration of the test substance
- Duration of observation period following administration: 14 days
- Frequency of observations and weighing:
Mortality/Viability: Twice daily
Body weights: Days 1 (pre-administration), 8 and 15
Clinical signs: At periodic intervals on the day of dosing (Day 1) and once daily thereafter, until Day 15.
- Necropsy: At the end of the observation period, all animals were sacrificed by oxygen/carbon dioxide procedure and subjected to necropsy. Descriptions of all internal macroscopic abnormalities were recorded.
- Other examinations performed: none - Statistics:
- No statistical analysis was performed (The method used is not intended to allow the calculation of a precise LD50 value).

Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- In an acute oral toxicity study with di-C16-C18 (evennumbered) alkyl tripropylenetetramine in rats, performed according to OECD/EC test guidelines, an LD50 >2000 mg/kg bw was determined.
- Executive summary:
The acute oral toxicity of di-C16-C18 (evennumbered) alkyl tripropylenetetramine was determined in accordance with OECD 423 (2001) and according to GLP principles. Initially, the substance was administered by oral gavage to a group of three female Wistar rats at 300 mg/kg bw. In a stepwise procedure two additional groups of three females were dosed at 2000 mg/kg bw. No mortality occurred. At 300 mg/kg bw, the animals showed no clinical signs. At 2000 mg/kg bw, hunched posture and/or piloerection were noted for the animals between Days 1 and 3. Body weight gain and necropsy did not show any abnormality. The acute oral toxicity (LD50) was determined to be >2000 mg/kg bw. Based on this result, di-C16-C18 (evennumbered) alkyl tripropylenetetramine does not need to be classified for acute toxicity by the oral route according to the Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures. According to the OECD 423 test guideline, the LD50 cut-off value was considered to exceed 5000 mg/kg bw.
