- Details on test animals or test system and environmental conditions:
- TEST ANIMALS
- Source: Charles River Laboratories, Research Models and Services, Germany GmbH, Sandhofer Weg 7, 97633 Sulzfeld, Germany
- Age at study initiation: Approx. 8 weeks
- Weight at study initiation: 171 - 184 g
- Fasting period before study: Food was offered ad libitum. Feeding was discontinued approx. 16 hours before administration; only tap water was then available ad libitum. After administration of the test item, food had been withheld for a further 3-4 hours.
- Housing: During the 14-day observation period the animals were kept in groups of 3 animals in MAKROLON cages (type III plus).
- Diet (e.g. ad libitum): Food was offered ad libitum. Feeding was discontinued approx. 16 hours before administration; only tap water was then available ad libitum. After administration of the test item, food had been withheld for a further 3-4 hours.
- Water (e.g. ad libitum): Drinking water in bottles was offered ad libitum.
- Acclimation period:At least 5 adaptation days
ENVIRONMENTAL CONDITIONS

IN-LIFE DATES: From: First dosing June 24, 2014 To: Termination of the in-life phase July 10, 2014
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- other: 2000 mg/kg: tap water, 5000 mg/kg: the test item was used as supplied
- Doses:
- 2 dose level groups: Dose levels 2000 and 5000 mg/kg b.w.
Administration volume 4.50 mL/kg b.w. - No. of animals per sex per dose:
- Number of animals 7 female animals; 1 animal at 5000 mg/kg b.w., 6 animals at 2000 mg/kg b.w.
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 1 test day and 2 recovery weeks
- Frequency of observations and weighing: Observations were performed before and immediately, 5, 15, 30 and 60 min, as well as 3, 6 and 24 hours after administration. All surviving animals were observed for a period of 14 days.
- Necropsy of survivors performed: yes
- Other examinations performed: clinical signs, body weight
During the follow-up period of two weeks, changes of skin and fur, eyes and mucous membranes, respiratory and the circulatory, autonomic and central nervous system and somatomotor activity as well as behaviour pattern were observed at least once a day until all symptoms subsided, thereafter each working day. Attention was also paid to possible tremors, convulsions, salivation, diarrhoea, lethargy, sleep and coma.
Observations on deaths were made at least once daily to minimize loss of animals during the study. Individual body weights were recorded before administration of the test item and thereafter in weekly intervals up to the end of the study and at death. Changes in weight were calculated and recorded.
At the end of the experiments, all surviving animals were sacrificed, dissected and inspected macroscopically. All gross pathological changes were recorded. - Statistics:
- No statistical analysis was performed (the method used is not intended to allow a calculation of a precise LD50 value).
Results and discussion
Effect levels
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 - < 5 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- 2000 mg Flocryl™ MADAM/MECL 75%/kg b.w. : None of the six female animals died prematurely.
5000 mg Flocryl™ MADAM/MECL 75%/kg b.w. : This animal died within 5 minutes after administration. - Clinical signs:
- other: 2000 mg Flocryl™ MADAM/MECL 75%/kg b.w. : Slightly reduced motility, slight ataxia and pilo-erection in 6 of 6 female animals, salivation in 4 animals and reddish discoloured lacrimation in 2 animals. 5000 mg Flocryl™ MADAM/MECL 75%/kg b.w. : Slightly red
- Gross pathology:
- No signs of abnormalities were noted at necropsy at any dose level.
Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The LD50 of the test substance in the rat by the oral route was greater than 2000 mg/kg bw but less than 5000 mg/kg bw.
