Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The key studies indicate that 2 -butoxyethanol is fully soluble in water at relevant environmental temperatures. Some supporting studies indicate lower solubility but this does not match with common observations. The key parameter adopted to indicate complete miscibility is therefore the same as the density. Water solubility is not expected to be sensitive to changes in pH or temperature (at least those likely to be encountered in under conceivable environmental conditions).
