Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Administrative data

Endpoint:
short-term repeated dose toxicity: other route
Type of information:
migrated information: read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
supporting study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Follows a methodology which is comparable in part with standard guidelines, does not have GLP. This result was obtained by valid read-across.

Examinations

Observations and examinations performed and frequency:
Groups of rats and mice were exposed to a single oral dose by the intraperitoneal route over a ten day period. The dose groups comprised 250 mg/kg/day, 500 mg/kg/day, 1000mg/kg/day and 2000 mg/kg/day respectively, and included a control group.

Applicant's summary and conclusion

Conclusions:
No reporting on clinical observations was provided in the original study. The results gave a NOAEL = 250 mg/kg (bw) via the intraperitoneal route for both the rat and mice.
