Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

There is no experimental chronic invertebrate toxicity data available, but QSAR predictions show that 2 -(2 -butoxyethoxy)ethanol is of low toxicity to invertebrates at chronic levels of exposure. Acute data show that toxicity is so low that chronic toxicity information is in any case unlikely to be required and should be sufficient to predict PEC:PNEC ratios are below one even with default assessment factors typical of acute data only.
