Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Results and discussion
Results of examinations
- Details on results:
- Clinical observations:
All animals survided until scheduled necropsy.
Ataxia and somnolence were observed persistently in the 750
mg/kg dose treated rats. Among females, addtionally
piloerection and prostration were noted sporadically.
In the higher dose treated rats, reduced locomotor activity,
reduced food consumption, slightly reduced body weight were
observed.
Laboratory findings:
In higher dose treatd females, elevated chlosterol and
alanine aminotransferase were observed and considered to be
of adaptative changes.
Effects in organs:
Elevated liver-to-body weights in higher dose treated rats
were observed and attributed to metabolic adaptation.
In the kidneys of higher dose treated males, moderate
severity hyaline change in the cortical tubules was
observed. Brain and kidney lesions observed in the 30 and
150 mg/kg treated animals were observed.
Effect levels
- Dose descriptor:
- NOAEL
- Effect level:
- 30 mg/kg bw/day (nominal)
- Basis for effect level:
- other: original NCD unit is mg/kg/day.

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.
