Additional information

Hydrolysis

Based on the molecular structure of the constituents of the substance, hydrolysis is not expected under environmentally relevant conditions.

Biodegradation in water

The degradation of the substance after 28 days is 16 %. Therefore, the substance is considered to be "Not Readily Biodegradable" (Weyers, 2010).

Biodegradation in water and sediment: simulation tests

In accordance with section 3 of REACH Annex XI, a study does not need to be conducted as, based on the exposure scenarios developed in the Chemical Safety Report, it is demonstrated and documented that throughout the life cycle Strictly Controlled Conditions as set out in Article 18(4)(a) to (f) of REACH do apply.

Biodegradation in soil

In accordance with section 3 of REACH Annex XI, a study does not need to be conducted as, based on the Exposure Scenarios developed in the Chemical Safety Report, it is demonstrated and documented that throughout the life cycle Strictly Controlled Conditions as set out in Article 18(4)(a) to (f) of REACH do apply.

Bioaccumulation: aquatic/sediment

In accordance with section 3 of REACH Annex XI, a study does not need to be conducted as, based on the Exposure Scenarios developed in the Chemical Safety Report, it is demonstrated and documented that throughout the life cycle Strictly Controlled Conditions as set out in Article 18(4)(a) to (f) of REACH do apply.

As the substance is an UVCB substance there is no distinct BCF but a range based on the single constituents. QSAR calculations on the bioconcentration factor of the five main constituents revealed BCF values in the range of 4-874.

Adsorption / desorption

The adsorption coefficient (log Koc) of the substance is 2.8 (Güdel, 2010).
