Description of key information

Additional information

Phototransformation in air

Estimated half-lives for the components of this UVCB substance range from 3.3 to 11.1 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

readily biodegradable (OECD Guideline 301 F).

 

Bioaccumulation

With a log Kow =3, the substance can be considered to have a low potential for bioaccumulation.

 

Adsorption/desorption

In 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 values for homologous components of this UVCB substance range from 1 to 10 L/kg for the lowest (least sorptive) and highest (most sorptive) molecular weight homologues. The components of this UVCB substance can be regarded as having low affinity for adsorption to soils and activated sludge biosolids.
