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

In accordance with column 2 of REACH Regulation No. 1907/2006 (EC), Annex VIII, Sect. 9.3.1, col. 2 adsorption/desorption testing can be waived, if due to physical chemical properties of test item a low adsorption potential is expected.

Urea 4 is insoluble in water. Thus, leaching potential of Urea 4 into soil can be excluded. Further, the substance is exclusively synthesised in a matrix and a direct exposure to soil can be excluded.
