Test animals
- Species:
- rat
- Strain:
- not specified
- Sex:
- not specified
- Details on test animals or test system and environmental conditions:
- TEST ANIMALS
- Age at study initiation: adult
Administration / exposure
- Route of administration:
- oral: feed
- Vehicle:
- not specified
- Duration and frequency of treatment / exposure:
- 28 days
Doses / concentrations
- Remarks:
- Doses / Concentrations:
0.1% in diet = 100 mg/kg bw (calculation based on the assumption of a an average rat body weight of 200 g and an average daily uptake of 20 g feed/animal)
- No. of animals per sex per dose / concentration:
- 9
- Control animals:
- not specified
- Details on dosing and sampling:
- PHARMACOKINETIC STUDY (distribution)
- Tissues and body fluids sampled: body fat; carcasses were frozen, dehydrated, and extracted for the test substance with hot chloroform. The radioactivity of crude fat, fatty acids, glycerol, and residue was determined.
- Time and frequency of sampling: at termination of the study, when the rats were killed
Results and discussion
Main ADME results
- Type:
- distribution
- Results:
- the test substance did not accumulate in body fat stores
Toxicokinetic / pharmacokinetic studies
- Details on distribution in tissues:
- A small portion (0.35 to 0.49 %) of the radioactivity was in crude fat, 0.15 to 0.32 % was in fatty acids, 0.01 to 0.07 % was found in glycerol, and 0.04 to 0.09 was found in the residue.
Applicant's summary and conclusion
- Conclusions:
- Administration of the test substance to rats via diet for 28 days did not result in an accumulation in body fat stores.
