- Water (e.g. ad libitum): drinking water (ad libitum)
- Acclimation period: >=5 days
ENVIRONMENTAL CONDITIONS
- Temperature (°C): 19-25
- Humidity (%): 30-70
- Air changes (per hr): >=15
- Photoperiod (hrs dark / hrs light): 12 hrs light/12 hrs dark
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- arachis oil
- Details on oral exposure:
- All animals were dose onced only by gavage, using a metal cannula attached to a graduated syringe. The volume administered to each animal was calculated according to the fasted bodyweight at the time of dosing. Treatment of animals was sequential. Sufficient time was allowed between each sex to confirm the survival of the previously dosed animals.
- Doses:
- 2000 mg/kg
- No. of animals per sex per dose:
- 3 animals per sex per dose (3 males at 2000 mg/kg and 3 females at 2000 mg/kg).
- Control animals:
- no
- Details on study design:
- The animals were observed for deaths or overt signs of toxicity 1/2, 1, 2 and 4 hours after dosing and subsquently once daily for fourteen days.
Individual bodyweights were recorded prior to dosing and 7 and 14 days after treatment.
At the end of the observation period the animals were killed cervical dislocation. All animals were subjected to gross pathological examination. This consisted of an external examinations and opening of the abdominal and thoracic cavities for examination of major organs. The appearance of any macroscopic abnormalties was recorded. No tissues were retained.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The acute oral median lethal dose (LD50) of the test material in the Sprague-Dawley CD (Crl: CD^(R) (SD) IGS BR) strain rat was estimated as being greater than 2500 mg/kg bodyweight.
No mortalies were noted in animals treated with 2000 mg/kg bodyweight. - Executive summary:
Introduction. The study was performed to assess the acute oral toxicity of the test material following a single oral administration in the Sprague-Dawley CD (Crl: CD® (SD) IGSBR) strain rat. The method was designed to meet the requirements of the following:
- OECD Guidelines for the Testing of Chemicals No. 423 "Acute Oral Toxicity - Acute Toxic Class Method" (adopted 22 March 1996)
- Commision Directive 96/54/EC Method B1 tris Acute Toxicity (Oral) - Acute Toxic Class Method
Method. A group of three fasted females was treated with 2000 mg/kg bodyweight. This was followed by a group of three fasted animals of the other sex at the same dose level.
The test material was administered orally as a suspension in arachis oil BP. Clinical signs and bodyweight development were monitored during the study. All animals were subjected to gross necropsy examination.
Mortality. There were no deaths.
Clinical Observations. Pink staining of the fur was noted in all animals one to four days after dosing. There were no other signs of systemic toxicity.
Bodyweight. All animals showed expected gains in bodyweight over the study period.
Necropsy. No abnormalities were noted at necropsy.
Conclusion.The acute oral median lethal dose (LD50) of the test material in the Sprague-Dawley CD (Crl: CD®(SD) IGS BR) strain rat was estimated as being greater than 2500 mg/kg bodyweight. No mortalities were noted in animals treated with 2000 mg/kg bodyweight.
