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

Description of key information

According to Table 9.3.1 Column 2 of the REACH regulation (1907/2006), an adsorption/desorption screening study does not need to be conducted if, based on the physicochemical properties of the substance, low potential for adsorption is expected (i.e. if the substance has a low octanol-water partition coefficient). Given that the weighted average log Pow value of e-Caprolactone, oligomeric reaction products with 2,2'-oxydiethanol is 1.8 (i.e. <3), low adsorption potential is expected and further studies are not considered necessary.

Key value for chemical safety assessment
