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.

Description of key information

Additional information

The components of the reaction mass of 2,2'-oxybisbutane (DSBE), DIPE, SBA and 2-methylpropan-2-ol (TBA) are considered to have a low potential to bioaccumulate as DIPE, TBA and SBA have a log Kow < 3, and DSBE is metabolised, resulting in 2 molecules of SBA. In mammalian systems SBA is either conjugated and excreted, or fairly rapidly metabolized by alcohol dehydrogenase to methyl ethyl ketone (MEK). For further discussion on bioaccumulation see PBT / vPvB Assessment (CSR, chapter 8).
