ABIOTIC DEGRADATION

DIRECT PHOTOLYSIS in Air, Water and Soil

The registration substance does not absorb light >290 nm (ozone band) and therefore a direct photolysis in air, water and soil will not occur.

INDIRECT PHOTOLYSIS in Air, Water and Soil

The registration substance may undergo OH radical induced indirect photolysis. The Half-life of the indirect photolysis can be estimated with US EPA AOPWIN Program calculating a low degradation half-life of 1.3h (12-hr day, 1.5E6 OH/cm3).

HYDROLYSIS

In prinicple the amid function of the registration substance can be cleaved abiotically but the half-life for the hydrolysis is >>100 years (US EPA Hydrowin Model). As the registration substance is readily biodegradable in an OECD 301B CO2 Evolution test (see IUCLID Chapter 5.2.1) a hydrolysis study need not to be conducted (REACH Regulation 2006/1907 Annex VIII, Column 2, 9.2.2.1).
