Endpoint:
adsorption / desorption: screening
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the physicochemical properties of the substance indicate that it can be expected to have a low potential for adsorption

Description of key information

According to Column 2 of REACH Annexes VIII and IX of Regulation (EC) No 1907/2006 a study on adsorption/desorption does not need to be conducted if the substance can be expected to have a low potential for adsorption based on its physicochemical properties. Hexagonal boron nitride is inorganic and has no relevant functional group for adsorption. Therefore, adsorption/desorption test is not necessary. 

Key value for chemical safety assessment
