Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Applicant's summary and conclusion

There was no evidence of maternal toxicity observed at any dose level tested. There
were no statistically significant differences in mean body weight, body weight change,
uterine weight, corrected body weight, food consumption, or uterine implantation data
Between treated and control animals. Additionally, there was no mortality or adverse
clinical/postmortem signs which were considered treatment-related. In the fetuses, there
was no evidence of growth retardation or increased fetal death in the treated groups
compared with controls. Additionally, there were no biologically significant differences
in total or individual variations or malformations (external, visceral, or skeletal) in the
treated groups when compared with controls on either a per fetus or per litter basis. Thtest material
was not considered embryotoxic nor teratogenic under the conditions of this study.
