- Sex:
- female
- Details on test animals or test system and environmental conditions:
- TEST ANIMALS
- Source: Charles River (UK) Ltd, Margate, Kent, UK.
- Age at study initiation: 8 - 12 weeks
- Weight at study initiation: 193 - 209 g
- Fasting period before study: overnight fast immediately before dosing and 3 to 4 hours ater dosing
- Housing: animals were housed in groups of three in suspended solid-floor polypropylene cages furnished with woodflakes
- Diet (e.g. ad libitum): free access to certified rat and mouse feed
- Water (e.g. ad libitum): free access to mains drinking water
- Acclimation period: at least five days
- Other: The animals were provided with environmental enrichment items which were considered not to contain any contaminant of a level that might have affected the purpose or integrity of the study
ENVIRONMENTAL CONDITIONS

- Humidity (%): 30 to 70 %
- Air changes (per hr): at least fifteen changes per hour
- Photoperiod (hrs dark / hrs light): twelve hours continuous light (06:00 to 18:00) and twelve hours darkness
IN-LIFE DATES: From: 30 March 2004 To: 21 April 2004
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- arachis oil
- Details on oral exposure:
- VEHICLE
- Concentration in vehicle: 200 mg/mL
- Amount of vehicle (if gavage): 10 mL/kg bw
- Justification for choice of vehicle: material does not dissolve in water
MAXIMUM DOSE VOLUME APPLIED: 10 mL/kg (the volume administered to each animal was calculated according to the fasted bodyweight at the time of dosing)
DOSAGE PREPARATION:
For the purpose of the study the test material was ground to a powder and then freshly prepared, as required, as a suspension at the appropriate concentration in arachis oil BP. Arachis oil BP was used because the test material did not dissolve/suspend in distilled water.
CLASS METHOD (if applicable)
- Rationale for the selection of the starting dose: material not expected to be toxic - Doses:
- single
- No. of animals per sex per dose:
- 6 (two groups of 3 animals)
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: The animals were observed for deaths or overt signs of toxicity ½, 1, 2 and 4 hours after dosing and subsequently once daily for fourteen days. Individual bodyweights were recorded prior to dosing and seven and fourteen days after treatment.
- Necropsy of survivors performed: yes
- Other examinations performed: clinical signs, body weight, gross pathology. - Statistics:
- none
Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Mortality:
- None of the animals died during the study.
- Clinical signs:
- other: Signs of systemic toxicity noted during the study were hunched posture, increased salivation, pilo-erection, noisy respiration and red/brown staining around the mouth. Animals appeared normal one or two days after dosing.
- Gross pathology:
- No abnormalities were noted at necropsy.
Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The acute oral median lethal dose (LD50) of the test material in the female Sprague-Dawley CD strain rat was estimated as being greater than 2000 mg/kg bodyweight.
- Executive summary:
The study was performed to assess the acute oral toxicity of the test material following a single oral administration in the Sprague-Dawley CD strain rat. The study used 6 female rats and followed the actute toxic-class method, in accordance with the OECD 423 guideline. The study was conducted to GLP standard in a certified laboratory.
All clinical signs observed had disappeared within 2 days. Bodyweight gain remained normal and no abnormalities were revealed at necrospy. The acute oral median lethal dose (LD50) of the test material in the female Sprague-Dawley CD strain rat was estimated to be greater than 2000 mg/kg bodyweight.
