TEST ANIMALS
- Source: Harlan Winkelmann, Borchen, Germany
- Age at study initiation: 6-10 weeks
- Average weight at study initiation: males 189 g; females 178 g
- Fasting period before study: from ca. 16 h before to 3 - 4 h after treatment
- Housing: in fully air-conditioned rooms in macrolon cages (type 4) on soft wood granulate in groups of 5 animals
- Diet: ssniff (R) R/M-H (V 1534), ad libitum
- Water: tap water, ad libitum
- Acclimation period: at least 7 days

ENVIRONMENTAL CONDITIONS
- Temperature: 22 +- 3 °C
- Humidity: 50 +- 20 %
- Photoperiod: 12 hrs dark / 12 hrs light
Route of administration:
oral: gavage
Vehicle:
other: sesame oil
Details on oral exposure:
The animals received the compound as a 20 % suspension in sesame oil, the administration volume being 10 ml/kg bw.
Doses:
2000 mg/kg bw
No. of animals per sex per dose:
5 animals per sex per dose
Control animals:
no
Details on study design:
The prepared test substance was administered by gavage to fasted animals at the stated dosage. The observation period following treatment lasted for 14 days. Symptoms were recorded twice every day (in the morning and in the afternoon), on weekends and public holidays only once. During this time the animals were weighed weekly. At the end of the observation period, the animals were killed by CO2 asphyxilation, dissected and examined for macroscopically visible changes.
Sex:
male/female
Dose descriptor:
LD50
Effect level:
> 2 000 mg/kg bw
Remarks on result:
other: no mortality occurred
Mortality:
No deaths occured during the whole study.
Clinical signs:
Bluish discoloured feces were observed after the administration of the test material. From day 4 until the end of the study no findings were observed.
Body weight:
Development of body weight was not impaired, except one female, which suffered a loss of body weight between day 8 and day 15.
Gross pathology:
No macroscopically visible changes were seen.

Additional information

Justification for classification or non-classification

Classification, Labelling, and Packaging Regulation (EC) No. 1272/2008

The available experimental test data are reliable and suitable for classification purposes under Regulation 1272/2008. No mortality occurred at the limit dose of 2000 mg/kg bw. As a result the substance is not considered to be classified for acute oral and dermal toxicity under Regulation (EC) No. 1272/2008, as amended for the seventh time in Regulation (EC) No 2015/1221.
