Description of key information
Additional information
Phototransformation in air
Estimated half-lives for the components of this UVCB substance range from 2.5 to 11.9 hours.
Hydrolysis
In accordance with Column 2 of REACH Annex VIII, the study does not need to be conducted as the substance is readily biodegradable. Ether bonds are stable and do not hydrolyse to a significant extent at environmental relevant condition.
Biodegradation
The % biodegradability for the substance was 84% in 26 days and therefore it can be considered as readily biodegradable.
Bioaccumulation
With a log Kow ≤3, the substance can be considered to have a low potential for bioaccumulation.
Adsorption/desorption
n accordance with Column 2 of REACH Annex IX, the study does not need to be conducted as the substance can be expected to have a low potential for sorption (log Kow ≤3). The estimated Koc value for homologous components of this UVCB substance was 10 L/kg for the full range of homologues (low -high molecular weight). The components of this UVCB substance can be regarded as having low affinity for adsorption to soils and activated sludge biosolids.
