- Source: Iffa Crédo, 69210 L'Arbresle, France
- Age at study initiation: approximately 8 weeks old
- Weight at study initiation: mean body weight of 279 ± 10 g for the males and 225 ± 2 g for the females
- Fasting period before study: no
- Housing: The animals were housed in groups of 4 to 7 animals of the same sex per cage during the acclimatization period and individually during the study. They were housed in polycarbona te cages ( 48 x 27 x 20 cm) during the acclimatization period, and (35.5 x 23.5 x 19.3 cm) throughout the study.

TEST MATERIAL
- Amount(s) applied (volume or weight with unit): 2.5ml/kg - Duration of exposure:
- Single
- Doses:
- 2000mg/kg
- No. of animals per sex per dose:
- 5

- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing:
Clinical signs: The animals were observed frequently after application of the test substance and at least once a day for 14 days in order to determine the reversibility or irreversibility of any clinical signs.
Mortality: The animals were checked frequently for mortality and signs of morbidity just after administration of the test substance and at least twice a day during the 14-day observation period.
Body weight: The animals were weighed individually just before application of the test substance and then on days 5, 8 and 15. The body weight gain of the treated animals was compared to a reference curve of C.I.T. control animals with the same initial weight.
- Necropsy of survivors performed: yes

- Conclusions:
- Under the experimental conditions, the dermal LD0 of the test substance n-HEPTYLAMINE was higher than 2000 mg/kg.
- Executive summary:
The potential acute toxicity of the test substance n-HEPTYLAMINE was evaluated in rats according to the recommendations of the O.E.C.D. Guideline No. 402 (O.E.C.D., 24th February 1987) administered by dermal route and the Principles of Good Laboratory Practice (O.E.C.D., 12th May 1981) . The test substance was applied in its original form directly to the skin of 10 Sprague-Dawley rats (5 males and 5 females) at a dose level of 2000 mg/kg, taking into consideration that the specific gravity (SG) of the test substance was 0.773. After 24 hours under a semi-occlusive dressing, no residual test substance was observed at removal of the dressing. The animals were checked for clinical signs, mortality and body weight gain for a period of 14 days after the single application of the test substance. A necropsy was performed on each animal sacrificed at the end of the study. No clinical signs were observed after application of the test substance. Between days 2 and 15, signs of necrosis of the skin without tissular lesions on the whole depth of the skin were observed on the area receiving the test substance. Between days 2 and 5, the body weight gain of the females slowed down and that of the males was reduced by 5 g. The body weight gain of all animals returned to normal thereafter. No deaths occurred at the dose level of 2000 mg/kg. Under our experimental conditions, the LD0 of the test substance n-HEPTYLAMINE when administered by dermal route in rats was higher than 2000 ng/kg.
