according to guideline
OECD Guideline 401 (Acute Oral Toxicity)
Principles of method if other than guideline:
Instead of "At least 5 rodents are used at each dose level. They should all be of the same sex", in this study 4 rats are used per dose level, 2 male and 2 female animals.

oral: gavage
propylene glycol
Details on oral exposure:

- Amount of vehicle (if gavage): 10ml/kg
- Justification for choice of vehicle: no data
- Lot/batch no. (if required): no data
- Purity: no data


On the day of dosing the test substance was suspended in propylene glycol and heated to 35ºC in order to get a homogeneous suspension and administered as a single dose using a stainless steel stomach cannula.

No. of animals per sex per dose:
Control animals:
Details on study design:
- Duration of observation period following administration: 14 days
- Frequency of observations and weighing: Cage-side observations were performed on the day of dosing (once every two hours) and daily thereafter. Individual body weights (with group means) were measured weekly. Body weights were also measured at death when found dead 24 hours or more following dosing.

Results and discussion

Preliminary study:
not performed
Effect levels
Dose descriptor:
Effect level:
> 200 - < 2 000 mg/kg bw
At 2000 mg/kg bw all animals died. One on the day of dosing and the others on day 1. At the other dose levels no deaths occurred.
Clinical signs:
other: Signs of toxicity, lethargy and a rough fur, were only observed in animals of the high dose group. At the other dose levels no signs of toxicity were observed.
Gross pathology:
Macroscopic examination o f animals at necropsy showed no abnormalities in the low and mid dose group and petechiae; a yellow liquid intestinal content and gas accumulation in the intestines in all animals of the high dose group.
Other findings:

Applicant's summary and conclusion

The oral LD50 value of Tallow tripropylene tetramine in Wistar rats is within the range of 300-2000 mg/kg body weight.
LD50 cut-off value is 500 mg/kg body weight.
Executive summary:

Three groups of Wistar rats; each comprising 2 males and 2 females, received a single oral dose at 25, 200 and 2000 mg/kg body weight; respectively. The incidence of mortalities for the sexes combined from low to high dose group was 0, 0 and 4. There was no evident sex related effect. All deaths occurred within 1 day of dosing. Signs of toxicity in animals of the high dose group were lethargy and a rough fur. No abnormal clinical behaviour was observed in animals of the 25 mg/kg and 200 mg/kg dose groups and no abnormalities at necroscopy. Group mean body weight gain for animals of the low and mid dose groups was nomal. Macroscopic examination of animals at necropsy revealed in all animals of the high dose group petechiae of the stomach, a yellow liquid intestinal content and gas accumulation in the intestines.

Based on the absence of signs of toxicity in the 200 mg/kg group as well as the absence of abnormalities in this group at necroscopy, it is considered unlikely that mortality would occur between 200 and 300 mg/kg. The anticipated LD50 would therefore be > 300 mg/kg, hence classified in Category 4.

Although not indicated in the report, for classification purposes for use in mixtures a LD50 cut-off value of 500 mg/kgbw is suggested.
