Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

According to column 2 of REACH annex VII the study needs only to be conducted if, based on the structure, surface activity is expected or can be predicted. If the water solubility is below 1 mg/l the test does not need to be conducted. 1,1’-DPE does not possess structural alerts for surface tension reducing properties (no distinct polar and non-polar structural elements of the molecule). Testing is therefore not required.
