Constituent 1
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: Batch No. 6F11027000
- Expiration date of the lot/batch: 17.11.2016
- Purity: 96%
Test animals

- female
- Details on test animals or test system and environmental conditions:
- TEST ANIMALS
- Source: Charles River, Sandhofer Weg 7, 97633 Sulzfeld, Germany
- Females nulliparous and non-pregnant: Yes
- Age at study initiation: 7-8 wks
- Fasting period before study: 3 hrs
- Housing: In groups of 3 animals in Tecniplast Type 2000P open cages (ca. 10% larger than Eurostandard Type IV cages)
- Diet: ad libitum
- Water: ad libitum
- Acclimation period: At least 5 days
ENVIRONMENTAL CONDITIONS
- Temperature (°C): 22 ± 3°C
- Humidity (%): 30-70%
- Air changes (per hr): 10 air changes per hour
- Photoperiod (hrs dark / hrs light): 12 h light/12 h dark, artificial lighting
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- corn oil
- Details on oral exposure:
- VEHICLE
- Amount of vehicle (if gavage): 4 mL/ kg bw per gavage
- Justification for choice of vehicle: As the test item's solubility in water is poor, corn oil was used as an organic solvent. Pre tests showed that the solubility of the test item in corn oil was sufficient.
- Lot/batch no. (if required): Sigma, Catalogue # 1636
- Purity: 100%
CLASS METHOD
- Rationale for the selection of the starting dose: A starting dose of 2000 mg/kg bw was determined based on information from former studies on the test item (single dose LD50 < 5000 mg/kg bw) - Doses:
- Planed: 2000 mg/kg, 300 mg/kg, 50 mg/kg, 5 mg/kg
- No. of animals per sex per dose:
- 6
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: For fatalities: twice within 4h after each application, daily for remainder of observation period thereafter. For clinical signs/behavior: daily. For body weight: once before application, then weekly
- Necropsy of survivors performed: Yes
- Other examinations performed: clinical signs, body weight, organ weights, histopathology, other: clinical signs (behavior) and body weight
Results and discussion
Effect levels
- Key result
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- All animals survived during the planned in-life period. No animals died during the study.
- Clinical signs:
- other: All animals survived during the planned in-life period. Only one animal (E54/0) showed a slight change of behavior shortly after the application (slight lethargy, piloerection at the head, slight abnormal walk).40 minutes later this change was not detecta
- Gross pathology:
- During necropsy no alterations were found. Only animal ESS/0 of the second run showed a slightly reddened thyroidea.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Remarks:
- according to EC 1278/2008 as amended
- Conclusions:
- Following the administration of a single dose of 2000 mg/kg body weight of the test item in 6 female rats, no animals died during the study and no animals showed severe suffering or moribundity. A slight reversible change of behavior was detected in one animal as well as minor weight loss in another animal. No distinct changes could be noted during necropsy. The LD50 was therefore expected to overlie 2000 mg/kg bodyweight.
- Executive summary:
Following the administration of a single dose of 2000 mg/kg body weight of the test item in 6 female rats, no animals died during the study and no animals showed severe suffering or moribundity. A slight reversible change of behavior was detected in one animal as well as minor weight loss in another animal. No distinct changes could be noted during necropsy. The LD50 was therefore expected to overlie 2000 mg/kg bodyweight.
