Key value for chemical safety assessment

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.
