Description of key information

Phototransformation in air

After evaporation or exposure to the air, the substance will be rapidly degraded by photochemical processes.

Hydrolysis

Hydrolysis was investigated according to OECD guideline 111. In this study the test item was completely hydrolyzed after 2 h at 50°C.

Additional information

Phototransformation in air

Based on a calculation according to AOPWIN v1.92, the substance is indirectly photodegraded by reaction with hydroxyl radicals in the atmosphere with a half-life (t1/2) of about 47 min taking into account a 24-h day and a mean OH radical concentration of 0.5E06 radicals per cm³.

 

Hydrolysis

 

The substance is readily biodegradable (cf. chapter 5.2). In Annex VIII of Regulation (EC) No 1907/2006, it is laid down that the study on hydrolysis does not need to be conducted if the substance is readily biodegradable.

In a supporting study according to OECD guideline 111 the test item was completely hydrolyzed after 2 h at 50 °C.
