Description of key information

The substance was tested for ready biodegradability according to OECD 301 F (key study). Based on the results, the substance is considered readily biodegradable. The Koc value of the substance is 1195 L/kg and the corresponding log Koc value is 3.1. This means that the substance adsorbs rather strongly to soils and sediments, according to FAO mobility classification, and that hence the substance is considered slightly mobile.

The CSA conducted for this substance shows that there is no risk for the environment, since Risk Characterization Ratios for all uses of this CSR are 0.01 or lower. According to REACH Annexes VIII to X, Column 2, Specific rules for adaptation from Column 1: Further degradation testing shall be considered if the chemical safety assessment […] indicates the need to investigate further the degradation of the substance”. Based on currently available data and current assessment, every usage covered by the chemical safety assessment is safe, whatever environmental compartment is considered. As a consequence, further studies to assess the fate of the substance in environmental compartments surface water/sediment, soil and groundwater are not necessary.
