Test material
Constituent 1
Test animals
- Species:
- rat
- Strain:
- Wistar
- Sex:
- female
- Details on test animals or test system and environmental conditions:
- The females were nulliparous and non pregnant. After an acclimatization period of at least 5 days the animals were selected at random and given a number unique within the study by indelible ink-marking on the tail and a number written on a cage card. At the start of the study the animals were 8 to 12 weeks of age. The body weight variation did not exceed +/-20% of the mean body weight at the start of the treatment.
Animals werehoused in groups of up to four in suspended solid-floor polypropylene cages furnished with woodflakes. With the exception of an overnight fast immediately before dosing and for approximately 3 to 4 hours after dosing, free access to mains drinking water and food was allowed throughout the study. The diet, drinking water and bedding were routinely analyzed and were considered not to contain any contaminants that would be reasonably be expected to affect the purpose or integrity of the study. The temperature and relative humidity were set to achieve limits of 19 to 25°C and 30 to 70% respectively. The rate of air exchange was at least fifteen changers per hour and the lighting was controlled by a time switch to give 12 hours continuous light and 12 hours darkness.
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- arachis oil
- Details on oral exposure:
- All animals were dosed once only by gavage, using a metal cannula attached to a graduated syringe. The volume administrated to each animal was calculated according to the fasted body weight at the time of dosing.
- Doses:
- 2000 mg/ kg
- No. of animals per sex per dose:
- 5 in total
- Control animals:
- no
- Details on study design:
- Clinical observations were made 30 minutes, 1, 2 and 4 hours after dosing and then daily for 14 days. Morbidity and mortality checks were made twice daily, early and late during normal working days, and once daily at weekends and public holidays.
- Statistics:
- Not performed
Results and discussion
- Preliminary study:
- 1 animal tests at 2000 mg/ kg.
No mortality observed

- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No mortality observed
- Clinical signs:
- other: There were no signs of systemic toxicity
- Gross pathology:
- No abnormalities were noted at necropsy
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The acute oral median lethal dose (LD50) of the test item in the female Wistar strain rat was estimated to be greater than 2000 mg/kg bw.
Results are considered scientifically valid to support a non classification. - Executive summary:
Acute oral toxicity to the test item was evaluated according to OECD Guideline 420 (Acute Oral Toxicity – Fixed Dose Method). The test item was administered by oral gavage to four fasted female rats (Wistar strain) at a dose level of 2000 mg/kg body weight. The test item did not cause any deaths nor signs of systemic toxicity. The acute oral median lethal dose (LD50) of the test item in female Wistar rats was estimated to be greater than 2000 mg/kg body weight. This results in the test item being unclassified according to GHS.
