Administrative data

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 substance has a low octanol water partition coefficient and the adsorption potential of this substance is related to this parameter
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
the study does not need to be conducted because the substance and its relevant degradation products decompose rapidly
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING
According to REACH Regulation (Annex VIII, 9.2.2.1, column 2), the study on adsorption/desorption does not need to be done if based on physico-chemical properties (e.g. low n-octanol/water partition coefficient log Pow) a low soil sorption is to be expected or based on the biodegradation the substance itself and its relevant degradation products break down quickly. Acylglycinate GCK-12H-T has a log Pow=-2.8 and proved to be readily biodegradable and fulfilling the 10-d-window criterion (93.7% biodegradation after 28 d). Experimental testing is therefore considered to be not necessary.
