Description of key information

Abiotic degradation:

Air: Based on estimation with the model Aopwin the substance undergoes in air rapid degradation. The DT50 values after reaction with hydroxyl radicals and ozone are 1.1 hours and 38.2 minutes respectively. The substance will not reach the stratosphere and is therefore not considered to be a long-range transported chemical in air.

Ozone depletion: The substance does not have an ozone depletion potential because it does not contain halogens and does not have the capacity to reach the stratosphere (GHS, 3rd Edition, CLP, 2008).

Water: In the aqueous phase a half life for hydrolysis of 3.4 hours at pH 7.5 and 37°C was concluded based on the read across substance.

Biotic degradation:

In a CO2 evolution test biodegradation screening study (OECD TG 301B), after 28 days exposure of domestic activated sludge to 16.0 mg/L (12.0 mg/L TOC) test material, between 22 and 55% biodegradation was observed. Based on these findings the substance is considered to be not readily biodegradable, but can be stated as inherently (primary) biodegradable.

Transport and distribution:

The adsorption potential Koc of the substance was estimated by KOCWIN Molecular Connectivity Index (MCI) as equal to 824.7 L/kg. Based on this value it is concluded that the substance may have a high potential for adsorption to solid surfaces and a low mobility in the water phase.
