Results and discussion
Main ADME resultsopen allclose all
- Type:
- absorption
- Results:
- No significant amounts of whitener were absorbed from the digestive tract of the rats.
- Type:
- distribution
- Results:
- No radioactive residues were found in blood, liver, kidney, brain, muscle, or fat 96 hours after dosing with the chemical.
- Type:
- metabolism
- Results:
- Details not available.
- Type:
- excretion
- Results:
- Following oral doses of 5 mg/kg of each of theFWAs to rats, rapid and complete excretion of radioactive material was observed, with an excretion half-life ranging from 7-13 hours.
- Type:
- excretion
- Results:
- Faeces were practically the only route of excretion, indicating, in combination with the short half life times, that no significant amounts of whitener were absorbed from the digestive tract.
Toxicokinetic / pharmacokinetic studies
- Details on absorption:
- Not applicable since the chemical does not have pharma application.
