Description of key information

Point 9.3.1, Column 2, Annex IX of Regulation 1907/2006 states that adsorption/desorption screening is not required of the substance and its relevant degradation products decompose rapidly.  The ready biodegradability of the substance has been determined to be 89% after 28 days and so it is considered that the substance undergoes rapid decomposition. On this basis, no adsorption/desorption testing is considered to be required.

However for the purpose of environmental risk assessment a KOC value of 1770 l/kg (MCI method) was estimated in KOCWIN v2.00 (EPI Suite v4.10). The MCI method Koc estimate has been used as it provides the most conservative value for PNEC sediment and soil.
