Results and discussion
Toxicokinetic / pharmacokinetic studies
- Details on absorption:
- Most of the radioactivity remained at the site of application (88 ± 2.3%).
- Details on distribution in tissues:
- Only traces of radioactivity were detected at other skin sites (0.2%).
- Details on excretion:
- Only traces of administered radioactivity were detected over a 72 h-period in urine (0.15 %), faeces (0.16 %), exhaled carbon dioxide (0.27 %) and cage wash (0.3%).
Metabolite characterisation studies
- Metabolites identified:
- not measured
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
