Additional information

In accordance with Section 2 of Annex XI of the Regulation (EC) 1907/2006 (REACH), it is considered justified to omit both the adsorption/desorption screening as required in point 9.3.1 of Annex VIII and the further testing for this endpoint as required in point 9.3.3 of Annex IX as it is considered that testing is not technically possible.

There is a lack of a suitable analytical technique for these studies, due to the substance being a complex mixture as well as being considered insoluble. It would not be possible to assign a relevant value for the adsorption constant due to the substance containing too many variable components.
