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.
