Results and discussion

Results: P0 (first parental generation)

Effect levels (P0)

Dose descriptor:
NOAEC
Effect level:
> 1 000 mg/kg bw/day
Based on:
test mat.
Sex:
male/female
Remarks on result:
other: Current available data from category members suggests no adverse effects would be seen up to the limit dose shown.
Remarks:
There is no data on the toxicity to reproduction for this substance. A testing proposal has been submitted for the substance 2 -(2 -(2-methoxyethoxy)ethoxy)ethanol and the results will be read across to this substance using a category approach with appropriate additional bridging studies that are currently in progress.
